What kind of sunglasses are more durable?

PC lens (carbonated polyester lens): tough, not easy to break, impact resistant, specially designated lens material for sports glasses, **higher than acrylic lens;

Glass sheets: slightly higher in clarity than resin, but the first is heavier, the second is easy to break (even if it is tempered glass);

Resin sheet: resin is a chemical substance with phenolic structure, characteristics: light weight, high temperature resistance, strong impact resistance, and can effectively block ultraviolet rays;

Nylon sheet: made of nylon, characteristics: very high elasticity, excellent optical quality, strong impact resistance, usually used as a protective item;

AC lens (acrylic lens): It has excellent and strong characteristics, light weight, high see-through, and good anti-fogging.

Polarizer: It is a polaroid film, its function is to only accept the light from one direction, and the light from other directions is blocked back, it is the principle of using the blinds to filter the stray light, so that we can see things more clearly.

Polarizer principle: In order to filter the sun's glare in the same direction as the sun shining on the water, land or snow, a special paint in the vertical direction is added to the lens, which is called a polarized lens.

Advantages: Eliminates glare, preferred by car drivers.

Protection against ultraviolet rays and a variety of harmful light in the sun prevents the occurrence of cataracts.

Dear, we're a bit alike! I also hate resin films, as long as it is accidentally touched, it is easy to have scratches, generally I will choose AC films, it is the kind of acrylic lenses, anti-fog is better, suitable for summer or autumn wear, I haven't bought many foreign brands, domestic is very good, I have a few at home, it is a domestic dolphin brand, strong and very attractive, every year they have some new products, recommend to you, you can go to the dolphin store to see it first!

It seems that your requirements for glasses are still very high, you go to ** search for 'visual life glasses store', the glasses in that store are good, they are all plates, not those injection molded frames, very textured.

You can go to Lujing Xuan to have a look, there are still more styles there, I bought a few pairs there, and I feel that the quality is quite good.

Let's go to the optician! The quality is still ***, and the UV protection function is also very good. Many domestic brands are relatively good, anyway, don't buy them online, there are really too many fakes.

Now there are many materials for sunglasses, but generally high-end ones don't use glass, not to mention the danger, the refractive index of glass is not good for the eyes, Carikari's lens material is good, from the first glasses, black zircon is used.

The most commonly used is crystal spectacle lenses, which have the advantage that the material is hard and not easy to wear. Cons:

Unable to fully absorb short-wave ultraviolet rays; Cannot reduce the transmittance of infrared rays; The density of the material is uneven, and if it contains impurities, there will be streaks and bubbles, causing birefringence, which will affect vision, 2. Glass material.

The main ingredient is silica, followed by boron trioxide and phosphorus pentoxide. Advantages: Good hardness, Disadvantages:

Heavy weight, with a specific gravity that is twice that of resin material. With the increase of the refractive index, the specific gravity increases significantly, resulting in uncomfortable wearing; The impact resistance is poor, and the mechanical damage is easy to cause eye damage, so the safety is poor.

3. PC lenses.

PC is a type of plastic, and polycarbonate is a polymer containing a carbonate base in the molecular chain, which is actually a sunglasses lens made of plastic. However, there are good and bad lenses. Our professional athletes use high-end products, not plastic sheet products for a few dollars.

It is characterized by being very light, good colorability, and inexpensive. The disadvantage is poor wear resistance and unstable optical properties.

4. Resin material.

The main component is organic matter, which has the advantages: light weight, good impact resistance, and relatively safe. Imported resin materials used by French brands, almost all major foreign brands use resin materials for sunglasses lenses.

Q: What kind of material is polarized lenses made of?

Answer: When light is reflected from the surface of an object, it is partially polarized to produce glare. The opposite effect of glare is to enhance brightness, weaken color saturation, blur the outline of the object, and make the eyes tired and uncomfortable.

Polarized spectacle lenses are made according to the principle of polarization of light and have a unique function of preferentially eliminating glare, which has a special effect on the driver and improves vision.

Landlord,I don't know much about glasses.,My friend recommended me to buy Karicari.,I don't know what kind of lenses it is.,Anyway, it's very comfortable to use.,The shopping guide said what kind of black zircon.,It should be a good material.。

The polarization is good, and the frames are aluminum-magnesium and classic pure titanium, light and non-corrosive. But some people like soft-framed PCs to see their personal hobbies, whether they like cool or soft. The shop is:**, Avenue shopping rabbit obediently. Check it out.

1. PC lens (carbonated polyester lens): tough, not easy to break, impact resistant, specially designated lens material for sports glasses, **higher than acrylic lens; 2. Glass sheet: the clarity is slightly higher than that of resin, but the first is heavy, and the second is easy to break (even if it is tempered glass); 3. Resin sheet:

Resin is a phenolic structure of chemicals, characteristics: light weight, high temperature resistance, strong impact resistance, can effectively block the ultraviolet rays; 4. Nylon sheet: made of nylon, characteristics:

Very high elasticity, excellent optical quality, strong impact resistance, usually used as protective items; 5. AC film (acrylic lens): It has excellent and strong characteristics, light weight, high transparency and good anti-fogging. 6. Polarizer:

It is the principle of blinds, filtering stray light, so that we can see things more clearly, polarizer Harahashi: in order to filter the glare of the sun shining on the water, land or snow in the equal direction of the dazzling ray, add a vertical special paint on the lens, which is called a polarized lens. Pros:

To eliminate glare, car drivers prefer sensitive stools to prevent ultraviolet rays and a variety of harmful light in the sun to prevent the occurrence of cataracts.

1. Plastic lenses.

UV400 resin lenses.

This is a lot of sunglasses brands like to use the material, light and unbrittle is its most obvious feature, the UV protection function of plastic lenses without any treatment is significantly better than that of glass lenses, and plastic lenses in the color treatment is also simpler. The disadvantage of plastic lenses is that they are abrasion resistant, they are easy to scratch, and the lenses are also easy to deform when they are impacted, so they should be more careful about their maintenance.

At present, there are three main plastic lens materials, namely plastic lenses, PC lenses, acrylic lenses, and 2. glass lenses.

Glass lenses. The most prominent advantage of glass lenses is that their optical properties are very stable, which is the consistent advantage of glass lenses, and it is the same when used in eyeglasses, and glass lenses are not easy to deform and will not be affected by the pressure of the frame. The disadvantage of glass lenses is that they are easy to break, and broken ones can easily cause damage to the eyes.

At present, the newly developed tempered glass lens has much more outstanding performance than ordinary glass lens, and is also regarded as a safety lens.

3. Polarized lenses.

Polarized lenses. This is a lens used in polarized sunglasses, which uses the principle of polarization of light to block glare from all sides out of the lens, so that the vision is clearer and safer when driving.

4. Tinted lenses.

Tinted lenses. It is also more photosensitive lenses, because of the change of light, the color of the lens will change accordingly, so that the eyes can adapt to different environments, in strong light, the color of the photochromic lens will be deepened, and under the light, the lens color will automatically become lighter. These silver lenses have been used in myopia sunglasses, and this type of self-tinting lens form is also considered to be the most convenient and aesthetically pleasing type of sunglasses, and is more popular than the clip-on type.

Sunglasses are divided into: sheets. 2.

Pieces of glass. 3.Resin sheets.

4.Nylon sheets. Slice.

6.Polarizers. 7.

Eccentric tablets. PC lenses (carbonate polyester lenses): strong and tough, not easy to crack, impact resistant, special lens material for sports glasses, **higher than acrylic lenses; Pieces of glass.

The transparency is slightly higher than that of resin, but the first is heavy and the second is brittle (even if the tempered glass); Resin Sheet: Resin is a chemical substance with a phenolic structure. Features:

Light weight, high temperature resistance, strong impact resistance, can effectively block ultraviolet rays; Nylon sheets: Made of nylon. Features:

Very high elasticity, excellent optical quality and high impact resistance. Usually used as protective equipment; AC Lens (Acrylic Lens): It has excellent strength and toughness, light weight, high see-through, and good anti-fogging.

Polarizer: It's a polaroid film. Its function is to receive light in only one direction and block light in the other directions.

It uses the principle of the shutter to filter out stray light so that we can see things more clearly.

Eccentric piece: It is to make its convex surface into a cross surface with non-parallel curvature, so that the refractive index of light is within the acceptable range of our eyes, so that our vision is clear and not dizzy, so as to achieve the pursuit of fashion while protecting our eyes.

Sunglass lenses are available in a color depth of % and 70%. 15% of them can be worn both indoors and outdoors. The lenses require the most suitable prescription, 34% for ordinary outdoor environments, 50% for the scorching sun and the seaside, and 70% for special purposes such as electric welding.

The color depth of the lens only affects the absorbance of visible light and has nothing to do with UV resistance. UV resistance is only related to the lens material, and space lenses are the best. The above is my answer, I hope it helps you.

Cellulose propionate, polycarbonate, epoxy, manganese-nickel alloy, aluminum-magnesium alloy material, titanium material, etc. These are the materials of sunglasses frames, most of the common sunglasses are made of these materials, choose sunglasses according to your face shape, and then choose lightweight and compact sunglasses.

There are many kinds of materials, such as stainless steel, acrylic, propionate, CP, PC, resin. You can choose according to your preferences.

There are nickel alloys, high nickel, stainless steel, aluminum alloys, and plastic materials. You can choose according to your face shape, or according to your usual life experience.

There are more than a dozen materials in total, so when choosing, you should choose the most suitable one according to your face shape and your own preferences.

What kind of sunglasses are better? If you don't choose sunglasses well, you won't be protected from radiation when you wear them! Life Tips, Life Tips, Life Tips, Life Tips.

Polarized nylon sheets are still OK, mainly depending on what price you need, the quality of each price is different, the main thing is to have anti-ultraviolet and polarizing functions.

Whether it is a glass sheet or a resin sheet, its material is brittle material. Therefore, it is easy to break in perforated and brushed glasses. The PC material is a viscous material, which has strong toughness and is not easy to break. Therefore, PC lenses developed with this material are very suitable for the use of perforated and brushed frames.

It is resistant to high temperatures, ultra-light, and ultra-impact-resistant.

Sunglasses are generally the most common optical plastic lenses. If you're going to bring sunglasses yourself, it's best to choose polarizers. It's more comfortable to wear. Follow-up:

It is a kind of sunglasses, but the lenses are bonded together in multiple layers, and there is a polarizing layer in the middle, which can eliminate the refraction and reflection of light, and can eliminate strong light, so you can see things more clearly. This is the difference from ordinary sunglasses, the others are the same as sunglasses, they can protect against ultraviolet rays, and the better the hardness of good quality, the better the clarity.

The answer is supplemented. 1.There are many ways to identify polarizers, but one of the simpler ones is to stack two polarizing lenses vertically, and the lenses will be opaque.

The reason for this is that polarizer lenses are specially designed to allow only parallel light to pass through the lens, and when the two lenses are stacked vertically, the light is mostly blocked. When you buy, as long as you have such a simple operation, you can immediately know the authenticity and quality of the product.

2.Generally, there is a discriminating board for polarizers, which does not look black with the naked eye, but with the polarizer it looks like you can see the black stripes that you do not see with the naked eye! Sunglasses are not available!

3.Grey or dark green lenses are a good choice for viewing objects in the most natural original color.

TR-90 material, with super tough memory resin material imported from Switzerland as the best frame material, has super flexibility, excellent anti-deformation performance, and light weight, which greatly reduces the weight of glasses. Strong impact resistance, effective impact resistance, good safety performance, is the material used in many sports glasses.

Aluminum-magnesium alloy material, widely used in mobile phones, laptops and other high-tech products, aluminum-magnesium alloy frames are also used in sunglasses, the frame is not easy to break, good impact, good durability, gloss and texture are good.

Titanium material, titanium alloy is also widely used in mirror frames. The density structure of titanium is better than that of titanium, and it has good elasticity, light weight and high hardness.
