Look at the Internet is said to TAC polarized lens.I don't know much about TAC material. Want to know what his character is PC can not be replaced?Hope professionals answer
PC material can also be made of PC polarized lenses used to make 3D glasses, but the cost is high, and its visual clarity is not high TAC.
TAC lens is a kind of composite material which is made up of multi layer material, which is often made into polarized lens. The utility model is composed of seven layers, namely, a polarizing layer in the middle, an ultraviolet filtering layer on both sides, a broken layer and a wear resistant layer.PC material can also be made of PC polarized lenses used to make 3D glasses, but the cost is high, and its visual clarity is not high TAC.
Polarized lenses say is a type of lens, his design type like shutters can filter, and is the same direction, 3D glasses are two pieces of mutually vertical Polaroid image, let eye to see different, resulting in three-dimensional feeling at the same distance. PC is the name of the material, has a strong impact resistance and toughness, security is very good, the disadvantage is not wear.
