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.
