PC 1.59 Anti-reflective Coating Polycarbonate Photochromic Lenses For Sporting Activities

Polycarbonate Lenses

PC lenses, also known as "space lenses", "universe lenses", chemical name is polycarbonate, is a thermoplastic material. That is, the raw material is in a solid state and is shaped into a lens after being heated. Therefore, the overheated lens of the lens will be distorted after being heated, which is not suitable for hot and humid occasions. PC lenses with toughness, not broken (2cm can be used for bullet-proof glass), it is also known as safety lenses. The proportion of only 2 grams per cubic centimeter, is currently used for ultra-light lens materials.

The benefits of PC lenses PC lenses are made of polycarbonate lenses, and ordinary resin (CR-39) lenses are essentially different!   1. PC lenses adhering to the excellent properties of raw materials impact resistance, and because of the high refractive index and light weight, greatly reducing the weight of the lens. Generally speaking, the weight of pc lenses is 57% lighter than common glass lenses, and 43% lighter than common resin lenses.   2. UV protection, can block more than 99.9% UV rays.   3. Not easy Yellow, can save 3~5 years.

Photochromic Lenses
