Sunglasses are a kind of vision care products to prevent the damage to human eyes caused by strong sunlight. With the improvement of people's material and cultural level, sunglasses can be used as special accessories for beauty or personal style. Our eyeball (lens) is very easy to absorb ultraviolet rays, and the damage of ultraviolet rays to the eyes is invisible. In order to protect the eyes, we must always wear sunglasses. Ophthalmologists recommend that you must always wear sunglasses to protect your eyes; this is because our eyeball (lens) is very easy to absorb ultraviolet rays, and the damage of ultraviolet rays has two prominent characteristics: 1. The damage of ultraviolet rays will accumulate. Since ultraviolet light is invisible light, it is difficult for people to perceive it intuitively. 2. The damage of ultraviolet rays to the eyes is irreversible, that is, irreparable. Such as: cataract surgery can only be replaced by intraocular lenses. Long-term damage to the eye can easily lead to damage to the cornea and retina, clouding of the lens until cataract occurs, resulting in permanent visual damage.

Sunglasses block unpleasant glare while protecting your eyes from UV rays. All thanks to metal powder filters that "select" light as it hits it. Colored glasses can selectively absorb some of the wavelengths that make up the sun's rays because they use very fine metal powders (iron, copper, nickel, etc.). In fact, when light hits the lens, it is eliminated based on a process called "destructive interference". That is, when certain wavelengths of light (in this case ultraviolet a, ultraviolet b, and sometimes infrared) pass through the lens, they cancel each other out on the inside of the lens, toward the eye. It is no accident that the overlapping waves that make up light waves: the crests of one wave combine with the troughs of adjacent waves, causing them to cancel each other out. The phenomenon of destructive interference depends on the index of refraction of the lens (that is, the degree to which light rays deviate from the air as they pass through different substances), and also on the thickness of the lens. In general, the thickness of the lens does not vary much, and the refractive index of the lens varies according to the difference in chemical composition. And sunglasses can't be in direct contact with the sun.

1. Anti-reflective protective lens: This lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, allowing you to see things more clearly and not disturbed by strong light. To test if your sunglasses really have anti-reflective protective lenses, point the glasses at the light source. If you see purple or green reflections, it means that the lenses are actually coated with anti-reflective protective film. 2. Colored lenses: also known as "tinted lenses", that is, in the process of lens production, some chemicals are added to make the lenses appear colored to absorb light of specific wavelengths. This is the type of lens most commonly used in sunglasses. 3. Colored lens: The effect of this lens is the same as that of the colored lens, only the way of making it is different. It is to paint the color on the surface of the lens. The most well-known one is the "gradual colored lens". Darkest at the top, then lighter at the bottom. Generally, sunglasses with degrees are mostly treated with colored lenses. 4. Polarized lens: In order to filter the dazzling light of the sun on the water, land or snow in the same direction, a special vertical coating is added to the lens, which is called polarized lens. Best for outdoor sports such as sea activities, skiing or fishing. 5. Color-changing lenses: also known as "photosensitive lenses". Because the chemical substance of silver halide is added to the lens, the original transparent and colorless lens will become a colored lens when exposed to strong light for protection, so it is suitable for indoor and outdoor use at the same time. 6. Sunglass clips: Sunglass clips are polarized sunglasses specially designed for myopic people, which can effectively prevent glare and UV rays. Especially suitable for driving, outdoor, fishing and other outdoor sports. Using polarized lens technology, the visual resolution is greatly improved. Eliminates 99% of reflected and scattered light, making your vision clearer and softer. The lens is specially enhanced with a film, which is effectively resistant to wear, scratches and impacts. 7. Night driving lens: The night driving lens should be able to block more than 80% of the strong light of the opponent's car, and the light transmittance of the main lens must be > 75%, and the observation road will not be affected. Wear a good pair of driving night vision goggles at night. Not only can you see the driving road clearly, but also can effectively reduce the dazzling glare and other harmful light from the headlights of the other party's car, and you can see the road normally while blocking the strong light, thus ensuring your driving safety.
