Sunglasses By Lens

There are five types of sunglasses lenses: anti-reflective protective lenses, colored lenses, tinted lenses, polarized lenses, and discolored lenses.

1. Anti-reflective protective lens: This lens is coated with a thin layer of magnesium fluoride on the surface to prevent the reflection of strong light, so that you can see things more clearly and not be disturbed by strong light. To check whether your sunglasses really use anti-reflective protective lenses, point the glasses at the light source. If you see purple or green reflections, it means that the lenses are indeed coated with anti-reflection protective film.

2. Color lenses: Also known as "stained lenses", during the lens manufacturing process, some chemicals are added to make the lenses appear color to absorb light of a specific wavelength. This is the most commonly used lens type for sunglasses.

3. Painted lenses: This lens exhibits the same effect as colored lenses, but is only made in a different way. It paints the color on the surface of the lens. The most well-known is "gradually painted lenses". The color is The top is the deepest, and then it goes down. Generally, sunglasses with a degree are mostly treated by painting.

4. Polarized lenses: In order to filter the dazzling light from the sun in equal directions on the water, land or snow, special vertical coatings are added to the lenses, which are called polarized lenses. Best for outdoor sports such as marine activities, skiing or fishing.

5. Discoloration lens: Some people call it "photosensitive lens". Because the silver halide chemical is added to the lens, the original transparent and colorless lens will become colored lens for protection when exposed to strong light, so it is suitable for indoor and outdoor use at the same time.

6. Sunglasses clip: sunglasses clips are polarized sunglasses designed for the short-sighted, effective anti-glare, anti-ultraviolet. Especially suitable for driving, outdoor, fishing and other outdoor sports. Adopting polarized lens technology, the visual resolution is greatly improved. Eliminates 99% of reflected and scattered light, making your field of vision clearer and softer. The lens is specially reinforced with film, which is effective in abrasion resistance, scratch resistance and impact resistance.

7. Driving lens at night: The driving lens at night should be able to block more than 80% of the glare of the other car. At the same time, the transmittance of the main lens must be> 75%. Observe the road is not affected. Wear a good driving night vision goggle at night. Not only can you clearly see the road surface, but also effectively reduce the glare and other harmful light from the other car's headlights.
