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