Regarding Ray Ban polarized glasses, there is a difference between Ray Ban polarized and non polariz

Polarizers are mainly designed for people who drive and work outdoors for a long time, so if you don't drive or don't work outdoors for a long time, there is no need to choose a polarizer. But be sure to buy **. Because the lenses of ** will not hurt the glasses.

It has nothing to do with radians. If it is, it may be a fake. If you promise to be **, then you can check your eyesight, or it may be because some people are not suitable for polarizers.

The basic Ray-Ban sunglasses polarized waist 2000 is reliable.

And glasses with curves should not be recessed to see things.

There's probably something wrong with your mirror.

I feel dizzy after staying for a long time, but sometimes my eyes are tired! You say recessed... This could be a fake! It has nothing to do with the curvature, but it's a big problem to see things recessed! You go to the seller and ask him!

My Ray-Ban is also **, but I found that China's Ray-Ban is very tricky, and more than 1000 things are not exquisite at all! There are small flaws!

I rely on it, I think it's bullying the Chinese!

Hello, the real Lei Peng is with anti-counterfeiting, Lei Peng's distributors are not the same as the regional optical stores, it is recommended that you go to a relatively large-scale optical store, where it is fidelity, if you are not used to wearing sunglasses with curvature, and your dizziness is also related, slowly adapt to it.

1. Different functions:

Unpolarized sunglasses do not have the function of blocking or converting polarized light, whereas polarized sunglasses do.

2. The degree of ultraviolet blocking is different

Non-polarized sunglasses only use the effect of light reduction, which can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block these harmful rays.

Polarized sunglasses can completely block dazzling glare caused by scattering, refraction, reflection and other reasons. At the same time, it can also completely block ultraviolet rays, which are harmful to the human eye.

3. The principle is different

The recognition of traffic lights by non-polarized sunglasses will produce a huge chromatic difference, which becomes a traffic hazard.

Polarizers are polarized light principles, and the objects seen will not change color, ensuring safety.

Dear customers and friends, hello! For commuting to work with glasses, I recommend choosing polarizers. Because polarizers can effectively reduce reflection and glare, you can see the road and surroundings more clearly when driving or walking, and improve the safety of driving and walking.

In addition, polarizers can also filter out some harmful UV rays and protect eye health. In contrast, although the photochromic lens also has a certain wide disturbance anti-ultraviolet function, its main function is to automatically adjust the light between indoor and outdoor to adapt to different environments. However, when walking in a car or under the quivering light, the photochromic mirror is not as effective as the polarizer.

In addition to this, it is recommended that you choose brand-safe products such as well-known brands such as Ray-Ban when buying glasses to ensure the quality and effectiveness of your glasses. In addition, it is also necessary to pay attention to the comfort and breathability of the glasses, so as not to have eye fatigue or other uncomfortable symptoms after wearing them for a long time. In short, for commuting to wear glasses, choosing a hollow anti-optic lens is a better choice, which can improve the safety of driving and walking, filter ultraviolet rays, and protect eye health.

The majority of Ray-Ban sunglasses are produced in Italy, and a very small amount is produced at the group's factories in China.

Product features: Super visual clarity: the lens has an average curvature, does not deform, and still feels comfortable when worn for a long time, which can prevent eye fatigue, headache and other conditions.

High color stability: The lenses will not change color or lighten no matter how long they have been exposed to sunlight.

Precision abrasive discs: The lenses are finely ground to the surface for superior optical clarity.

Scratch resistance: The natural hardness of glass can effectively prevent scratches and make glasses more durable.

Impact Resistance: To protect the eyes, each pair of lenses has undergone a 5 8 inch steel ball drop impact test to ensure impact resistance.

UV Protection: Blocks harmful UV rays to protect the eyes from eye injuries caused by sunlight and snow radiation.

Isolate other harmful rays: Isolate infrared rays to keep your eyes cool and comfortable, and isolate blue light to enhance color contrast, and your vision is doubled and clear.

8.The shape is rugged and chic, with good eye protection.

Ray-Ban uses a large number of glass polarizing technology, which has better imaging clarity and better color reproduction than ordinary plastic polarized lenses, especially suitable for driving, and is shatter-resistant.

There are two types of polarizers: resin polarizers and glass polarizers.

Advantages of resin polarizers:

1.Lightweight.

2.Less prone to breakage: In the unlikely event that the lens is broken, it will have fewer fragments and be less sharp, minimizing injuries to the eyes and face.

3.Can be dyed: Plastic lenses are easy to dye, and can be moderately matched with clothing and fashion.

4.Can block ultraviolet rays: Almost completely blocks ultraviolet rays with a wavelength of less than 350mm, and the effect is far better than glass lenses.

5.Strong anti-fogging: Because the thermal conductivity of plastic lenses is lower than that of glass, it is not easy to be blurred due to steam and hot water, and even if blurring occurs, it will disappear quickly.

6.Anti-dent: Generally, high-heat and small-volume substances are easy to cause dents and spots on the glass sheet, but if it hits the plastic lens, it will automatically pop open and will not cause any marks on the surface of the lens.

7.The surface reflection of plastic lenses is lower than that of ordinary glass lenses, and they are less dazzling.

8.Resin bifocals have no chromatic aberration, which is due to the fact that resin bifocals lenses are constructed in one piece, so there is less chromatic aberration than fused glass bifocals.

9.Plastic lenses are resistant to a wide range of chemicals and solvents, and almost all household solvents and chemicals will not affect or damage them.

Disadvantages of resin polarizers.

1.Easy to scratch: Plastic lenses have less scratch resistance than glass lenses, but they can be improved by case hardening, but the effect is limited.

2.It is easy to deform when framing: this is due to the fact that the density of plastic lenses is lower than that of glass lenses.

3.Not resistant to high temperatures: Although the resin is a thermosetting material, once the multilayer film is coated, the surface of the multilayer film may crack due to high temperatures.

Advantages of glass polarizers.

1. High hardness: the surface is not easy to be scratched, and it is more wear-resistant than resin sheets.

2. High density: the film will not be deformed, which will affect its polarizing effect because of improper film loading. The density of the resin sheet is smaller, and the willfulness is much stronger than that of the glass sheet, if the film is not properly installed, or the shape of the glasses itself is not very consistent, it will be deformed, affecting the polarization effect.

3. Strong light transmittance: The light transmittance of glass sheets is generally stronger than that of resin sheets, and the clarity is stronger.

Disadvantages of glass polarizers.

1. Heavy weight: Because its density is much higher than that of resin sheets, glass glasses are generally heavier than resin glasses.

2. Fragile: As we all know, glass is fragile. As a result, it has a poor ability to strike hard.

3. Expensive: The grinding technology of polarized glass sheet is high, and the production process is more troublesome, so the general glass polarizer is used for medium and high-end glasses.

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."At the same time, there is usually 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! "

The upstairs method can only identify polarizers, but not Ray-Ban, you go to the counter to see the real one, you know, the difference is very subtle, but the real and false are easy to identify together.

For example, the lenses of 3025 are all glass, and the RB lettering on the left spectacle lens and the lettering on the lower part of the crossbar above the nose bridge are really fine and clear, very deep and uniform.
