What kind of lens material for sunglasses is better?

Sunglasses lenses are divided into several categories：

1. PC sheet (carbonated polyester lens): strong, not easy to break, resistant to impact, specially designated lens material for sports glasses, the price is higher than that of acrylic lenses;

2. Glass: the clarity is slightly higher than that of resin, but the first is heavier, and the second is easy to break (even tempered glass);
3. Resin sheet: Resin is a chemical substance with a phenolic structure. Features: light weight, high temperature resistance, strong impact resistance, and can effectively block ultraviolet rays;
4. Nylon sheet: made of nylon, features: very high elasticity, excellent optical quality, strong impact resistance, usually used as protective items;
5. AC film (acrylic lens): It has excellent toughness, light weight, high perspective and good fog resistance.
6. Polarizer: It is a polaroid. Its function is to only accept light from one direction, and block the light from other directions. It uses the principle of blinds to filter stray light, so that we can see things more clearly

The principle of polarizer: In order to filter the dazzling light of the sun on the water, land or snow in the same direction, a special coating in the vertical direction is added to the lens, which is called polarized lens.

Pros: Eliminates glare, preferred by motorists

Protects against UV rays and various harmful rays of the sun to prevent cataracts
