Place of Origin
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
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.
In general, photochromic film lenses are both for indoor and outdoor activities lens. In the room or at night, the lenses color are basically transparent, the same as the ordinary lenses, like high light transmission performance, relieve visual fatigue,make you see the world more clear. Lens under the action of ultraviolet light in the sun color, ultraviolet dark color change, deep, shallow light-colored ultraviolet light, isolated from UV damage, anytime, anywhere to protect your eyes.

|Super Hydrophobic Coating|
|To protect the uncoated lenses from scratch resistance||To protect the lens effectively from refle ction, enhance functional and charity of your vision||To make the lens waterproof, antistatic, anti slip and oil resistance.|
|Depending on the layers of coating, lenses differ in functionality. Coating consists of much technicality as much as lenses do, here is how lens coating works' for your reference.|
