Memory glasses can be made to have the same appearance as ordinary metal glasses or titanium glasses, but their functions have been revolutionaryly improved and can withstand repeated twisting, high pressure or drops, quickly restoring their original appearance without damage. But some people may have questions, how expensive are memory glasses? 1. The process of memory glasses is relatively complicated. Compared with ordinary metal glasses and titanium glasses, the welding of memory frames is more complicated. Since the two materials cannot be welded together directly, a layer of nickel metal needs to be plated on the surface and then welded with other metals or titanium. The adhesion of the nickel must be very strong so that it can stick together and be twisted or squeezed repeatedly without falling off. 2. Material cost is high. On one side is memory metal or memory titanium. We only use memory materials imported from Japan or Germany. After receiving the materials, we must conduct repeated tests. After more than 500 times of 90-degree twisting, more than 500 times of 90-degree bending, and -30°C ultra-low temperature testing, the function is still good. Therefore, the quality of materials directly affects the quality of memory glasses. We only use high-quality materials. On the other hand, due to the use of memory material welding, the requirements for ordinary metal or titanium materials are also higher, and the cost will be higher than ordinary metal or titanium frames. 3. The cost of electroplating and color spraying is relatively high. High-quality memory glasses must be able to withstand repeated bending, twisting and even falling back to their original shape, and the surface plating or painting must not have any cracks or damage. Therefore, the requirements for the surface are particularly high, and higher-quality color inkjet materials, more advanced technology, and stricter quality control must be used. Why are memory glasses expensive? To summarize the above points, the costs of technology, materials, and surface treatment are different. A pair of memory metal glasses is about $2 more expensive than ordinary metal glasses of the same style and color. A pair of memory titanium glasses is about $3 more expensive than ordinary titanium glasses of the same style and color.

Here are five details that make acetate glasses different:   Material Composition: Acetate glasses are made from a plant-based plastic material called cellulose acetate. This material is derived from cotton or wood pulp and is processed to create a lightweight yet durable frame material. In contrast, many other types of glasses frames are made from metal or synthetic plastics.   Lightweight: Acetate frames are much lighter than metal frames, making them comfortable to wear for extended periods of time. This is especially beneficial for those who wear glasses all day long.   Flexibility: Acetate is a flexible material, allowing the frames to withstand some bending and flexing without breaking. This flexibility also makes acetate frames more comfortable to wear as they conform to the shape of the wearer's face.   Hypoallergenic: Acetate is hypoallergenic, meaning it is unlikely to cause allergic reactions or irritation for most people. This is an important consideration for those with sensitive skin or allergies to certain metals or plastics.   Color and Design Options: Acetate frames offer a wide range of color and design options. The material can be dyed in various hues, patterns, and finishes, allowing for more customization and personalization compared to metal frames. Acetate frames are also often decorated with intricate detailing and textures, adding a unique aesthetic appeal.

How can you fall in love with a pair of glasses at first sight? As a professional glasses manufacturer, let’s talk about 4 details that make metal glasses unique. high quality raw materials The first is that high-quality raw materials must be used, which is one of the key factors in making high-end metal glasses. High-quality raw materials have higher purity, fewer impurities, and purer colors. Under the same process conditions, the manufactured products can be of higher quality. Precision mold Making a pair of high-end metal glasses sometimes requires multiple sets of molds. The quality of the mold directly determines the quality of these parts. Therefore, we must attach great importance to the production of molds, pay attention to every detail of making molds, accuracy, smoothness, etc., and consider every link carefully. Only in this way can the selected high-quality materials be pressed again and again in the mold. Produce perfect eyewear parts. For example, for the pattern on the surface of metal glasses, you must first ensure that the pattern of the mold is perfect, and the corners of each pattern are smooth and delicate. Therefore, when making the mold, it is very important to manually polish the concave part of the pattern over and over again. perfect polish A perfect pair of high-end metal glasses, in addition to having a perfect shape, must also have a smooth appearance. Cut out the different metal lens parts and then use an electric welder to weld them together perfectly. Then, tumbling again and again, hand polishing is repeated again and again until the metal surface shines. In this process, every link of the roller machine, the raw materials of the roller, the hand-polished materials and the operator's skills are very important, and every detail must be paid attention to. Customized craftsmanship Each type of metallic glass has its own characteristics. Different designs such as circular and three-dimensional reflect different styles. Even if it is the same pair of metal glasses, some parts are three-dimensional, some are round, or other different shapes. style, so during the production process, you have to customize different styles of crafts for each type of metal glasses to ensure that every detail of the glasses can present the most perfect effect. For example, a stainless steel sheet metal glass cut to form a front frame with a bevel. When making this kind of metallic glass, most manufacturers cut out the shape and bevel at one time, and then complete it by rolling and polishing. In the production of glasses, the effect of bevel is not obvious. It looks like a bevel or a curved surface. This becomes a pair of glasses without personality and soul. Therefore, you have to separate the process of making the bevel, cut the front frame, and then go through the first tumbling and hand-sanding, and the surface of the metal will become very smooth and delicate. At this time, the diamond cutting process is used to make the bevel, and then after tumbling and polishing, it can be regarded as a perfect high-end metal glasses.

As an important tool for vision correction and facial decoration, glasses have accompanied mankind for a long time. However, traditional eyewear designs are often limited by material performance and cannot take into account comfort, durability and aesthetics. With the advancement of technology, the emergence of memory metal frames has brought revolutionary changes to the glasses industry. Memory metal frames are mainly made of shape memory alloy materials such as nickel titanium alloy. This alloy has the unique property of being able to change its shape at one temperature and return to its original shape at another temperature. This allows the memory metal frame to automatically adjust according to the user's face shape, ensuring wearing comfort and stability. Memory metal frames have many advantages over traditional metal frames. First of all, its material is extremely lightweight, which significantly reduces the feeling of squeezing on the bridge of the nose and skin. This means users will not feel uncomfortable even if worn for long periods of time. Secondly, memory metal frames are extremely elastic and can resist deformation and damage. This means that even when subject to external impact or improper use, the frame can quickly return to its original shape, maintaining its original beauty and performance. In addition, memory metal frames offer excellent stability. Because it self-returns, it maintains its original shape and quality no matter how it is bent or twisted during use. This makes memory metal frames ideal for those looking for high quality and durability. Of course, there are some potential problems with memory metal frames. For example, if you bend it too much or if you wear the same pair of glasses for a long time, the frame may lose its shape memory function, causing deformation. In addition, although the memory metal material itself has excellent corrosion resistance, it may still be damaged if it is exposed to harsh environments for a long time. However, these problems are not enough to overshadow the many advantages of memory metal frames. In fact, with the continuous development of technology, more and more brands and designers are beginning to use memory metal materials to make glasses. These glasses not only provide excellent performance and comfort, but also have unique aesthetic value, making them a favorite in the fashion industry. Overall, the emergence of memory metal frames has brought revolutionary changes to the eyewear industry. With its lightweight, good elasticity and strong stability, it provides users with a more comfortable, durable and beautiful wearing experience. Although there are still some potential problems, with the continuous advancement of technology and optimization of materials, I believe that memory metal frames will continue to exert their unique advantages in the future and become the choice of more people.

In a glass jar filled with cold water, a spring is stretched. When the spring is put into hot water, the spring automatically shrinks. The spring returns to its original shape in cold water, but shrinks in hot water. The spring can be stretched and contracted, contracted and stretched again an unlimited number of times. These are made of a smart metal with memory, whose microstructure has two relatively stable states. At high temperatures the alloy can be turned into any shape you want, and at lower temperatures the alloy Can be stretched, but if it is reheated it will remember its original shape and change back. This material is called memory metal. What are the characteristics of memory metal frames? Compared with ordinary spectacle frames, the biggest feature of memory metal frames is that they have the function of memory shape. Therefore, this kind of frame will not be unable to recover due to accidental bending. It already has the function of restoring its shape, so it is not necessary but cannot be bent. At the same time, the characteristics of memory metal can prevent rusting in water for a long time, so it is widely used in many industries, such as the glasses industry, photography industry, etc. Because the frames are relatively lightweight, they are favored by many consumers. Specific advantages of memory metal eyeglass frames 1. Extremely lightweight: Memory metal materials are inherently lighter than metal materials, so there is less pressure on the bridge of the nose and skin during wearing. 2. Excellent elasticity: Memory metal frames are super elastic, so they will never deform, and can be so obvious that the temples and mirror rings on both sides are pulled into a line. 3. Stable performance: Because it can automatically return to its original shape after bending, it has strong stability. It also has the advantages of high temperature resistance, corrosion resistance, and does not cause skin allergies. 4. Easy and comfortable to wear: Memory metal is light and can fit on the side of the face, so memory metal frames are easier and more comfortable to wear.

This article takes Metal Sunglasses as an example to talk about the oil injection process of Metal Eyewear. We know that metal glasses can use electroplating process, and titanium glasses mainly use IP electroplating process, but these colors are relatively rare and generally There are gold, silver, gun, rose gold, etc. Some brighter colors must use spraying process, also called oil spraying. It can be said that the oil injection process is also one of the most commonly used coloring processes for metal glasses. This article mainly explains the color spraying principle of metal glasses and titanium eyewear frames. Spray a layer of colored paint on the surface of the glasses frame. 2. The basic process of color spraying. Rack washing - electric base (electro nickel, IP, black chrome, white chrome base, etc.) - drying (baking) - spray color oil - drying - QC shipment 3. Advantages and disadvantages of spray color. It has rich colors and good gloss, and can be mixed into various colors. The disadvantage is that the adhesion is average, it is relatively easy to discolor and scratch. 4. Applicable glasses types. Various gold frames. For mid-to-low-end eyeglass frames, and some colors that cannot be covered by water plating or IP electroplating, the oil spray process must be used. In addition, there are some two-color glasses, such as two-color glasses with gold and black colors. Generally, the gold color is first applied, and then black is sprayed (then erase the areas where gold needs to appear, or apply isolation oil in advance, and then spray black paint, Just clean it off); 5. Color surface of oil injection process. Generally, there are light color, matte color, two-color and gradient color, etc. Since the oil injection process is mainly made by mixing toner, in theory it can be adjusted to any color you want. 6. Other related matters. Some factories make injection molded frames or plate frames. In order to save costs (and spend less time polishing), after the frames are completed, a thin layer of transparent oil is sprayed on the entire glasses frame to make the surface of the glasses appear brighter. . But the texture is still not as good as the effect of direct polishing. This process is commonly used for plastic glasses and TR90 glasses, while plate glasses are generally rarely used.

The main coloring processes for metal sunglasses include electroplating, oil spraying, etc. The following mainly talks about the electroplating process of metal frames. Electrophoretic coating, commonly known as water plating, is the most commonly used electroplating method for metal eyeglass frames. It is an electroplating process that colors the surface of the frame through electrolysis. Most of the metal glasses we see, including metal optical glasses, and metal sunglasses, have their surfaces completed by water plating. 1. Principle of water plating. Water plating is a process that uses electrolysis to deposit metal or alloy on the surface of a workpiece to form a uniform, dense, and well-bonded metal layer. For example, electrogolding means placing the spectacle frame in an electroplating gold vat (the gold vat is filled with a prepared electroplating liquid, and real gold is dissolved in it through chemical means), and then the machine is started, and a thin layer of gold is attached to the surface of the frame. . 2. The basic process of water plating: cleaning the frame (pickling) - drying - hanging rack (hanging on a special rack) - discharge and plating red, first electrolyte the background color (usually silver - electrolyte and then dry ( Drying) - Put the required color into the electroplating tank - Start the electroplating machine (the darker the color, the longer the electroplating time) - Take out the rack to dry (dry) - Electrophoresis glue (or spray glue, mainly (Protective, and complementary color) -- Drying (drying) -- QC shipment 3. Advantages and disadvantages of water plating: 3.1 Rich colors and good gloss. Common ones include gold, silver, gun color, rose gold, etc. You can also add the required color to the top layer of glue to make the color of the spectacle frame richer, such as red. , black, yellow, blue, etc. In order to save costs, there are many low-end and mid-range metal frames that are electroplated with a very light gold color (or even silver) first through an electroplating cylinder, and then add color powder to the glue to achieve the final effect. Looks like gold color. But the brightness will be worse than that of real gold. If you want electric matte color, the glue on the surface is matte glue. 3.2 The cost is relatively low. Comparing common coloring processes, IP electroplating has the highest cost, water plating is medium, and general color spraying is relatively the lowest. (The price reference for water plating of an ordinary metal frame: electric silver or electric nickel is about 3 yuan, ordinary gold is about 4 yuan, and gold is about 7 yuan. Two-color electroplating will increase the cost depending on the difficulty). 3.3 Good adhesion. It is better than ordinary spray color, but worse than IP plating. The glue on the electroplating surface plays a very critical role in adhesion. The glue and glue spraying process directly determine the quality of its adhesion. For example, some glues can only guarantee the anti-sweat test for 24 hours, while some glues can last up to 65 hours, and some can even spray a second glue, and the anti-sweat test can reach more than 72 hours. 4. The water plating process is suitable for various types of glasses, mainly various metal frames, such as metal optical glasses, metal sunglasses, and various metal accessories for plate glasses, horn glasses, etc. The materials include stainless steel, white copper, manganese, etc. 5. Main color expression of electroplating. 1. Light color. After electroplating, a layer of transparent glue is added to the surface and then baked to dry. This can not only increase the gloss of the electroplated surface, but also increase its adhesion. 2. Matt color. After electroplating, a layer of matte glue is added to the surface, so that the effect is matte and dull. But there will also be a special metallic texture. 3. Sand color. Before electroplating, put the glasses frame in a sandblasting machine for sandblasting, then take it out for electroplating and then apply glue. The resulting surface is bright and sandy, and the sandblasting frame is also called a smooth sanding frame. 4. Scan color. After electroplating, apply glossy or matte glue normally, and then use a color scanner (similar to a grinder, but with different wheels) to sweep out stripes, usually along the line. The resulting effect has many thin stripes, like pavement swept with a broom. The disadvantage is that the anti-oxidation ability of the color scanning frame will be reduced because it destroys the surface adhesive layer. In addition, the joints between the various parts of the glasses are often not visible, which also affects the appearance. 5. Two-color or multi-color glasses. Refers to a pair of glasses with two colors or multiple colors. This is also a common way, usually by applying isolation oil on certain areas, and after electromagnetic or spraying the second color, wash off the areas where the isolation oil has been applied to reveal the first color. If no isolation oil is applied, it must be wiped off manually. The two-color process is usually combined with oil spraying. 6. Other knowledge. 5.1 There are generally two methods of silver plating. The most common is nickel plating, which is relatively cheap and the silver plated has a very light yellow color; the other is handle plating, which is a more environmentally friendly method. It looks whiter and brighter, with a light cyan color, more like platinum. This kind of cost is slightly more expensive; 5.2 Frame electroplating base color. The main function of the base layer is to increase adhesion and increase smoothness (just like painting a wall before painting a base layer). Common bases include 1) Nickel base 2) Copper base 3) IP base (better adhesion, extra money) 3) Black base (if it's black, it has good adhesion, extra money) 4) White chrome bottom etc. 5.3 Metal glasses can also use IP electricity. The adhesion of IP plating will be stronger and it is completely harmless to the skin. However, the cost of IP plating is much higher, so ordinary metal frames are generally rarely used.

Sunglasses are one of the most common products nowadays. Sunglasses come in a wide variety of types and colors, such as the currently popular acetate sunglasses (Acetate Sunglasses), metal sunglasses (Metal Sunglasses), titanium sunglasses (Titanium Sunglasses), etc. It also There is one quality indicator that is very important, and that is the falling ball test. The falling ball test is mainly for sunglasses. Sunglasses are one of the most important accessories for sunglasses. In addition to basic functions such as UV protection, their impact resistance is also very important. They can ensure that your eyes will not be hurt by lens fragments when you accidentally fall. FDA requires sunglasses lenses imported into the United States to comply with the lens impact resistance test requirements of 21CFR801.410, also known as the drop ball test. The ball drop test is to drop a steel ball on the convex surface of the lens from a certain height to observe whether the lens is broken. FDA uses it to test the impact resistance of lenses. The FDA mainly tests lenses. During the test, the lenses will be framed with a clamp for this test. The steel ball is required to have a diameter of 0.625 inches, a weight equivalent to 1 ounce dropped from a height of 50 inches, and the lens is required not to be broken. When lenses or sunglasses are exported to the United States, they need to pass the drop ball test, also called the drop test. According to the standard 21 CFR801.410. Steel balls used for drop impact tests to prove that the batch of products exported to the United States meet the standard requirements and qualifications for impact resistance. When exporting related goods to the United States, you should note that not only all FDA manufacturer and product registration numbers must be provided during U.S. customs clearance, but also the following factory batch quality inspection documents must be provided. Certification Statement of Impact Resistance Impact-resistant lens manufacturer's statement of compliance (that is, the manufacturer declares to the FDA that it has conducted a pre-factory impact test/drop ball test in accordance with FDA regulations and passed the test, signed by the person in charge of the manufacturer) document). lmpact Resistance Test Report Impact Resistance Test Report (also called drop ball test report; the drop ball test is the basic test for the final batch testing of all the above-mentioned related lenses to prove that the batch of products exported to the United States meets the impact resistance standard requirements and is qualified. Usually, the test report will only be provided when the relevant customs specifically requires it. Generally, the above statement can be used as proof of compliance). Sunglasses are the main product of our factory, including acetate sunglasses, metal sunglasses and titanium sunglasses. Sunglasses are not manufactured by us, but when we purchase sunglasses, we pay great attention to the qualifications of the lens factory. Generally, they will pass strict various tests. After we receive the lenses, we will also conduct detailed inspections, including appearance inspection and functional inspection, including a ball drop test.

Titanium Eyewear is one of the most common types of eyewear. It is lighter and more elastic than Acetate Eyewear and Metal Evewear, so it is very suitable for use as myopia glasses. Titanium glasses are generally divided into pure titanium glasses and Beta titanium glasses. In this article, we will mainly take a look at the advantages of pure titanium glasses. First, let’s understand what titanium is. Titanium is a pure metal with a specific gravity of 4.5, high toughness, no magnetic reaction, and non-allergic to the skin. It is widely used in space technology, jewelry, surgical tools and other fields. It is one of the most high-end materials in the eyewear industry. Pure titanium generally refers to a-titanium metal materials with a titanium purity of more than 89%, which is infinitely close to 100%. This metal is characterized by high melting point, light material, strong corrosion resistance, and strong electroplating layer. So besides that, what are the advantages of pure titanium eyeglass frames? 1. The main advantage of pure titanium spectacle frames is that they are very light. Among spectacle materials, in addition to carbon fiber and aluminum materials, which have the reputation of "black gold", spectacle frames made of pure titanium are the lightest, but carbon fiber and The manufacturing process of aluminum glasses is more complicated, and the glasses produced are generally wider. Unlike titanium glasses, which can make the frame very thin, titanium glasses are actually lighter than aluminum glasses (Aluminum Eyewear) and carbon fiber glasses. 2. Glasses frames made of pure titanium are light and comfortable, more ergonomic, and have good flexibility. They will not deform, fade, or cause skin allergies after long-term use, and are relatively durable. The titanium material itself does not cause human skin allergies, and a layer of IP plating is added to the surface of the titanium glasses. IP plating not only has good adhesion, but also does not cause skin allergies. 3. Titanium is one of the indispensable materials for modern aerospace science, marine science, nuclear power generation and other cutting-edge sciences; titanium is 48% lighter than ordinary metal frames, resistant to acid and alkali, corrosion resistance, high stability, high strength, and good It has the advantages of elasticity, ergonomics, and titanium is non-toxic to the human body. No radiation. 4. Pure titanium has special current characteristics, which can guide electron fluctuations to generate ions, making the current tend to ionize. Positive and negative ions can quickly adjust the adverse effects caused by electromagnetic waves causing chaos in the body's biological currents, and have beneficial physiological effects on the human body. In addition, titanium alloy also has the effect of relaxing muscles and soothing the mind on the human body. Compared with B titanium glasses, pure titanium glasses are less elastic, but the cost is much cheaper. Therefore, when making glasses, B titanium is often used in thinner parts, such as the middle beam or spleen, so as to maintain the weight of the frame and make the glasses flexible.

We know that wearing glasses not only corrects vision, but also blocks and protects us from the sun. If you choose glasses that suit you, they can also help modify your face shape and enhance your personal image. If you choose incorrect glasses, it can be counterproductive. Men and women with big faces should pay special attention to the type and color of frames. If you are not careful, your face will look even bigger. Today I will talk to you about how to choose glasses for big faces. Of course, there are many types of big faces. Although they are all big faces, there are still tips for matching glasses with different face shapes. 1. If you have a round face, it is recommended to wear flat and wide glasses, such as rectangular or olive-shaped frames, which can effectively modify the round face shape and make the round face look more slender. As for the frame, it is recommended to choose a slightly thicker type, such as acetate glasses. Choosing dark, cool lens colors can also have the effect of visually tightening the face. However, if you choose red, yellow and other brightly colored lenses or glasses with too thin frame lines, your round face will often appear larger and unaffordable. to modify the face shape. 2. If you have a long face. It is recommended to wear slightly larger round and square frames to reduce the elongation of the face. Secondly, the upper part of the glasses should be flat and aligned with the eyebrows, while the lower part should be round. It can cover part of the face, making the face look smaller and highlighting the temperament of the face. But the frame should not be too wide. If it is wider than the face, it will make the face look longer. 3. If you have a big face, it is recommended to choose light-colored lenses and metal frames, and glasses with the curvature of the frames extending under the eyebrows. You can also choose glasses without frames, which can help reduce the width of the upper part of the face and at the same time The effect of showing a small face. 4. If you have a square face. It is recommended to wear glasses with arc frames, such as round retro glasses or preppy glasses with thick top and thin bottom. In short, people with square faces should not wear square-framed glasses, otherwise the facial lines will be more obvious. As for the color of glasses, if your complexion is not very white, for example, it should be close to wheat color. It is recommended that you do not choose brightly colored frames, such as bright red or purple, as this will make the whole look very uncoordinated. But if your skin is white and tender and you are a cute girl, then bright red frames are also an option. The combination of fair skin and bright red frames makes the whole person energetic and full of motivation. Currently, there are several types of frames on the market: full frame, half frame, frameless, etc. For people with large faces, glasses with large frames are a good choice. Try not to choose rimless or half-rim glasses, which may make your face look wider. When we buy glasses, we must not only choose the appearance and color that suits us, but also pay attention to their quality. Also try to choose glasses materials that are harmless to the skin. There are many types of glasses currently, including Acetate Eyewear, Metal Eyewear, Titanium Eyewear, Horn glasses and Wooden glasses made of natural materials. Needless to say, acetate glasses, Titanium glasses and horn glasses are environmentally friendly and harmless to human skin. High-end metal glasses are also harmless to humans after undergoing a surface plating process. The key is to find regular stores to buy glasses and choose brand glasses with viable quality. Especially when you are purchasing glasses for myopia, you should not only pay attention to the quality of the frames, but also pay more attention to the quality of the lenses and professional glasses.

Do you like oversize glasses? When choosing frames, most people will prefer oversize glasses, which have diverse and novel shapes and can also modify their face shape. In fact, not everyone is suitable for wearing oversize glasses. An important parameter for optometry and glasses-pupillary distance: When wearing glasses, the optometrist will use a pupillary distance meter to measure it. The pupillary distance is the distance between the pupils. It is the distance between the centers of the pupils of the two eyes when the eyes are facing straight or parallel. distance. Interpupillary distance is an important indicator of the quality of glasses. When fitting glasses, the distance between the centers of the two lenses must be consistent with the patient's interpupillary distance. Otherwise, even if the prescription is correct, the patient will feel uncomfortable after wearing the glasses and affect vision.  Compared with normal-sized frames, the offset position between the optical center point and the pupil of oversize glasses will be larger. For example, a oversize frame may be suitable for an interpupillary distance of 75 mm, but the eyeglass wearer's own interpupillary distance is only 60mm, with an offset of a dozen millimeters. In order to match your interpupillary distance, the optical center point of the lens can only be moved inward. This will cause a phenomenon: the middle of the lens is thin, the inner side is thick, and the outer side is thickest. It is equivalent to putting a pair of prisms in front of the eyes. , after the light is refracted, the wearer is prone to double images when looking at things. Over time, symptoms such as dizziness and visual fatigue will occur. This is the "prism effect". Under normal circumstances, it is not recommended for people with high myopia to wear frames that are too large. Even if they choose lenses with a high refractive index, if the frames are too large, the lenses will appear particularly thick, unsightly, and heavy. Wearing them for a long time can cause the bridge of the nose to break. It doesn't feel good. In addition, if the wearer lowers his head or shakes his head slightly, it is easy for the glasses to slip. Therefore, if you want to wear a pair of large-frame glasses that suits you, you must go to a professional optometry institution for medical optometry and choose glasses that suit you based on your actual situation. Do not blindly pursue good looks and let your eyes suffer. harm.

I believe many myopic people have experienced discomfort caused by long-term wearing of glasses that presses against the backs of their ears and the bridge of their noses. A company in the United States has designed a glasses frame that is not only made of lightweight materials, but also has a stylish design, bringing a more comfortable experience to people who wear glasses for a long time. The glasses frame is made of biodegradable materials, which is environmentally friendly. The material has its own color and does not require additional coating. Users do not have to worry about the coating peeling off and affecting the beauty of the glasses frame. The ends of the temples are designed with grooves to prevent the glasses from slipping, so users don’t have to hold them up often. The hinge screws are very strong and the temples will not come loose easily. In addition, the glasses frame material is very durable and will not be damaged even if it is accidentally stepped on or dropped to the ground.

There are many styles of Evewear nowadays, and it is very important to choose the one that suits you. Sometimes choosing a glasses frame that suits you can also add a lot of points to your appearance. The right glasses can add vitality to your face and create a better look. However, in the face of a wide variety of eyewear styles, such as Acetate Eyewear, Metal Eyewear, Titanium Eyewear, and Buffalohorn eyewear and Wood Eyewear made of natural materials, etc. , with various colors and shapes, each with its own advantages and disadvantages, how to choose? How to match the shape of the face and the shape of the glasses? This article mainly talks about how to match the face shape and the shape of glasses. I hope it will be helpful to you. 1. Rimless glasses Rimless glasses are perfect for round faces. If you have a round face, no other shape of glasses will suit you better than rimless frames, which will blend perfectly with your face. 2. Full frame glasses Round faces want to visually become oval. It can be changed through changes in color and pattern: a color gradient from dark to light from top to bottom can make the face look less rounded. The upper dark edge of the glasses can be fitted to deepen the eyebrow line. 3. Semi-rimless glasses. This retro classic eyewear style has become popular again recently. Since half-rim frames only emphasize the upper part of the eyebrow line, they only shorten the face once compared to full-rim glasses. But girls usually prefer this. What else does the shape of half-rim glasses do? It’s very personal, very stylish. Our tip: Business women can choose a unique upper edge that can highlight the sophistication of an elegant lady. The choice of glasses frames is still relatively important. Choosing a pair of glasses that suits you can beautify yourself well. When choosing glasses, you can choose different glasses to match according to your face shape. If you really don’t know how to choose, you can also refer to the suggestions of your friends or opticians. If you want to know more information about our company and products, please visit our website at https://www.belieyeglasses.com.

The laser welding machine uses the pulse laser with the wavelength of 1064 run generated by the laser to radiate the surface of the workpiece after beam expansion, reflection and focusing. The surface heat is diffused internally through the heat conduction. The width, energy, peak power, repetition frequency and other parameters of the laser pulse are precisely controlled digitally to melt the workpiece and form a specific molten pool, so as to realize laser welding of the workpiece, Complete precision welding that traditional processes cannot achieve. (1) Scope of application: At present, high-grade spectacle frames have gradually adopted the laser welding process, and the main Applied Materials is stainless steel. Materials with high melting points such as titanium. Through the interaction between laser and the welded object, a highly concentrated heat source area is formed at the welded area in a very short period of time. The heat energy melts and cools the welded object area, forming a solid solder joint and weld seam. (2) Advantages of laser welding ① Laser welding can realize spot welding, butt welding, overlap welding, seal welding, etc. for thin-walled materials and precision parts. ② High laser power, high aspect ratio of weld seam, small heat affected area, small deformation, and fast welding speed. ③ The welding seam is of high quality, flat and beautiful, without pores, and the toughness of the welded material is at least equivalent to that of the parent material. ④ Humanized design, LCD display, and centralized button operation are simpler. ⑤ The four-dimensional ball screw workbench adopts an imported control system, with an optional rotating workbench. It can achieve automatic welding such as spot welding, linear welding, and circumferential welding, with a wide range of applications, high accuracy, and fast speed. (3) Precautions for laser welding machine: laser, like ordinary light, has biological effects (such as thermal effect, optical effect, pressure effect and electromagnetic field effect). While this biological effect brings benefits to human beings, it will also cause direct or indirect damage to human tissues such as eyes, skin and nervous system if there is no protection or poor protection. In order to ensure the safety and protection during laser welding, laser hazards must be strictly controlled, and engineering control, personal protection and safety management must be done well. ① Engineering control: refers to the safety measures taken on the structure of a laser or laser processing system, mainly including: protective covers - used to prevent workers from receiving more than the maximum allowable exposure; Safety interlock - refers to an automatic device connected to a protective cover that can prevent radiation when the protective cover is removed; Safe optical path - sealing off optical paths that may cause combustion or secondary radiation due to radiation; Key switch - refers to the laser turning when the key is removed; Beam termination - In order to ensure that the laser beam does not exceed the controlled processing area, a beam terminator or attenuator can be used. ② Personal protection: mainly refers to wearing fire-resistant and heat-resistant laser protective clothing, laser protective glasses that can selectively attenuate specific laser wavelengths, laser protective masks that can protect ultraviolet laser sources, and laser protective gloves that can avoid damage caused by direct or scattered laser. ③ Safety management: mainly includes setting up specialized agencies or personnel, clarifying responsibilities and rights (including safety training and medical supervision, etc.).

In the glasses industry, high-frequency machine welding technology has rapidly emerged in recent years, bringing a revolutionary breakthrough to the production of eyeglass frames. This advanced welding process not only improves production efficiency, but also enhances the quality and reliability of the eyeglass frame. High frequency machine welding is a non-contact welding method that uses welding wire (usually 40% -70% silver content) and auxiliary flux to melt in the weld seam of the workpiece to complete the joint of two welded workpieces, with a welding temperature of 560-900 ℃. It is not limited by the geometric shape of the welded parts, and has the advantages of not damaging or crushing the welded parts. At the same time, its welds are beautiful, firm, and reliable. Scope of application: Metal eyewear frames made of various copper alloys and stainless steel materials. Maintenance methods for high-frequency machines: ① Every six months, engineers and welding supervisors open the top and front covers of the equipment, discharge residual charges on the high-voltage components to the ground, and remove internal dust and water to prevent the high-voltage transformer from getting damp. ② Check whether the ground wire and fan operate normally during use. ③ Change the cooling water frequently and check its water volume during use. If the water volume is low, it indicates that there is scale in the water pipe, and the water pipe needs to be pickled. ④ Every 1-2 months, the engineer and welding supervisor inspect the machine head. If there are any water droplets, accumulated water, or moisture, they should be removed in a timely manner to avoid causing high-voltage arc to burn the capacitor. ⑤ If there is copper rust on the connection between the sensing head and the machine head, it should be polished with sandpaper to ensure good contact. ⑥ When the sensing head is wound, its sensing coil has a diameter of 5-8 mm and a length of 130-155 mm. It should not be too long, otherwise it will affect its power. Precautions: ① When winding the sensing head, the turns should be separated from each other to avoid short circuits and burning other components. ② When winding the sensing head, there should be no flattening or dead corners to prevent the cooling water from flowing and burning the sensing ring. ③ It is strictly prohibited to place the workpiece tightly against the two poles of the induction ring during operation to avoid causing sparks, burning through the induction ring and other parts. ④ If the temperature is found to be too high during operation, rest should be paused and work can continue when the temperature is appropriate. Alternatively, two machines can be used alternately to extend the service life of the equipment. ⑤ If a fire or abnormal noise is found inside the machine head, it should be promptly reported to the welding supervisor or engineer for handling. The high-frequency machine welding technology has brought revolutionary breakthroughs to the production of eyeglass frames. Its efficient and precise welding method not only improves production efficiency, but also improves the quality and reliability of the eyeglass frame. With the continuous development and application of this technology, we believe that the glasses industry will usher in a brighter future.

A metal eyeglass frame is a general term for devices that are made of metal materials and can hold and fix various types of lenses, except for parts such as nose rests and leg covers that directly come into contact with the human skin. There are three types of metal spectacle frames: full frame, half frame, and frameless. The functions of the metal glasses frame include: being able to fix various types of lenses according to the prescription; The material is stable, reliable, safe, and harmless to the skin; Lightweight, sturdy, and not deformed; Easy to use and comfortable to wear; Strong, beautiful, and lightweight. The main frame of the metal glasses frame is welded from metal parts, and the processing of metal parts mainly involves stamping, oil pressure, cutting, etching, casting, and machining metal plates and wires of different specifications and sizes of materials. The processing techniques used for different types of spare parts vary. Welding processing is a method of combining the metal parts used in each pair of glasses frame with different welding equipment. There are three common welding methods for metal spectacle frames: high-frequency machine welding, laser welding and titanium welding. These three welding processes are applicable to different materials. Due to different welding processes and materials, the welding points are different.

1. Focimeter, also known as a film reader, is an essential device that can read the degree on the glasses, whether it is spherical or astigmatic, as well as the optometry data on the finished lens. The main function is to allow us to mark the optical center on the glasses before processing, and if there is astigmatism, we can also mark the axis position. 2. The production of center glasses requires the use of a center instrument, which is used to adsorb suction cups onto the glasses, especially those with astigmatism. The center gauge can accurately align the axis position with the upper diameter slot of the suction cup, avoiding the deviation of the astigmatism axis position. 3. Hole punch Hole punch is used to punch holes when making formwork. If the configuration specifications of the glasses store are relatively high, such as using a fully automatic edge grinder to directly scan the eyeglass frame without making a template, then this small machine does not need to be configured. 4. Grinding machine is an essential equipment for the production and processing of glasses. The selection of grinding machines should not only be based on individual economic strength, but also vary according to the type of glasses processed. For example, the common type of glasses is mainly resin glasses. Nowadays, there are many materials for glasses, including mainstream resin glasses, glass glasses, and PC glasses. At this point, choosing a grinding machine is targeted. Some grinding machines can not only grind glass glasses, but also resin glasses and PC lenses, which will be much more expensive than this machine. 5. After grinding out the glasses of the edge guide machine, the edge guide operation is usually required, and at this time, the edge guide machine is needed. Whether it is full frame glasses, half frame glasses, or full frame glasses, edge guiding operation is required. Sometimes the edge guide machine can also be used for manual repair of glasses. Although the edge guiding operation can be carried out on a grinding machine, the operating space is limited, so the edge guiding machine is necessary. 6. The slotting machine is only used for making half frame glasses, but it is also a necessary equipment for glasses production because we need to process glasses according to customer preferences. Some people like the whole frame, some like half frames, some like frameless glasses, and each person has their own preferences. We can only enrich ourselves and be prepared. 7. Slotting Hole punch Slotting Hole punch is a special machine with slotting and punching functions, but it is not the combination of the above slotting machine and Hole punch. It is a device specifically designed for making frameless glasses. 8. The selection and configuration of baking lamps is mainly to soften the glasses frame when the deformation of the plate glasses needs to be repaired. Making it into a lamp shape is actually like a hair dryer. Belongs to the selection of instruments. 9. Ultrasonic cleaning The function of Ultrasonic cleaning is to use ultrasonic waves to clean the stains on glasses, which can be used to clean the frame or mirror. The cleaned glasses look completely new. 10. During the production process of glasses, the polishing machine is mainly used to polish the edges of glasses, such as half frame, frameless glasses, or full frame glasses. It can polish the edges to make the processed glasses more beautiful. If you want to know more information about our company and products, please visit our website at https://www.belieyeglasses.com.

Glasses, I believe everyone is familiar with them. Nowadays, eight out of ten people wear glasses, and every day they talk and hold glasses in their hands. When it comes to the parameters of glasses, many people can easily obtain them, such as refractive index, ratio, film layer, multiple, and so on. But do you really understand the production process of glasses? Do you know how many processes a small glasses in front of you need to go through? According to the mold assembly table, cleaned and qualified molds are combined in different ways with sealing rings or adhesive tapes, and a dust-free production workshop is used. The cleanliness must meet the quality requirements of water, oil, and dust free. 1. Filling Inject raw materials that have reached a certain viscosity through the sealing ring manually or mechanically into the assembly mold, check the sealing performance of the sealing equipment, and ensure that the quality meets the requirements. 2. One-time curing Send the filled mold to the curing furnace for heating, and heat different specifications of glasses according to different curing curves and control programs, resulting in different curing times. 3. Detachment The semi-finished products after solidification in the production of glasses are made of glass molds on both sides and transparent resin glasses in the middle. Separate the produced glasses from the substrate, resulting in the birth of rough glasses. 4. Trimming and cleaning After separating the rough glasses from the mold, they are polished. Due to the diameter of the rough glasses being about 4mm larger than the required glasses, the edges of the trimmed glasses are smooth, making it easy for later processing. After trimming the glasses, there are unreacted raw material monomers and powder under the grinding edge on the surface, and they are cleaned using an ultrasonic cleaning tank. 5. Secondary curing The function of secondary curing in glasses production is to eliminate stress inside the glasses and repair the surface of the glasses, making the dents on the surface of the glasses smoother. Finally, the glasses after secondary curing are inspected and stored in the warehouse. 6. Hardening Soaking, alkali treatment, surface soaking, alkali treatment, rinsing, water cutting, drying, cooling, soaking hardening, preparation for drying and other sequential hardening treatments are carried out. The hardening solution mainly forms a transparent film, increases the surface hardness of the glasses, and enhances the adhesion between the coating film and the substrate surface. Hardening inspection, curing. After passing the inspection, send the glasses into the oven for hardening and solidification. 7. Coating Place the chuck filled with glasses into the coating machine for coating. The purpose of painting is to reduce the reflection of light, but it is impossible to avoid the reflection of light. There will always be residual colors on the surface of the glasses, which means that the coated glasses are radiation resistant, anti-static, scratch resistant, and pollution resistant, making it easier to clean.
