PC lenses (commonly known as: the universe sheet, space film) is derived from a material scientist to make space exploration equipment can adapt to the special environment of space and out of the study, it is commonly known: the universe or space film sheet. PC resin is an excellent thermoplastic material, particularly suitable for the production of spectacle lenses.

PC lenses impact resistant resin sheet than 10 times, 60 times stronger than glass, it is the world's most impact resistant lenses, this material is commonly known as post-thick bulletproof glass, PC made of viscous material, toughness, easy to break.

PC material itself has UV protection, so the PC lens plus either white sheet or film has a long-lasting, good isolation UV wavelength of 290nm-380nm.

Polarized lens functions:
when under daytime sunlight, Polarized lens can more effectively block harmful ultraviolet rays, anti-glare, allowing you to more clearly see the front of the view. Plus principle polarizer, (lens polarization angle and radian precision optics design principle, only allowed polarization direction consistent light through, while the other strong light source (such as from the sun, water, glass, asphalt light) because the direction of polarization after reflection and filtered , thereby eliminating external light interference, avoid presbyopia, blinding, dazzling and so on, so that vision becomes more clear and soft, you can more effectively prevent the head of the glare, allowing you to see more clearly while driving, far-sighted, non-reflective, non-glare! ! ! !
Polarized lenses outstanding features:
 between the visible wavelength 380NM-780NM, sunlight is generally what we see during the day, a mix light from Seven color : red, orange, yellow, green, cyan, blue, purple color and UV wavelength 380NM, is one kind of invisible harmful rays can cause eye conjunctivitis, corneal if long-term exposure, it could lead to cataracts, efficient filter layer polarized lenses filter out 100% of ultraviolet (UVA, UAB, UVC).
 polarized lenses eliminate glare: reflected light, glare, glare. Reflected light and light everywhere, the human eye vision disturbances such as automotive glass, water, snow and road glare, or glare from the direct sun, the people can not see clear. usually colored sunglasses completely unable to eliminate these annoying light, polarized lenses can completely eliminate glare, reflected light and glare, its thin film polarizing lens column intermediate layer, like window blinds, all kinds of chaotic light such as retroreflective reflective glare or direct glare are being small dense polarizing column barrier on the outside, so that the light becomes parallel light entering your eyes.
 to strengthen the surface of the lens: polarized lenses through high-tech surface hardening, the lens is several times stronger than the anti-wear, anti-scratch ability.
When the TAC change color lenses are exposed to UV light, trillions of photochromic molecules in the lens begin to change structure.  This reaction is what causes the lenses to darken.
All lenses that adapt to light use photochromic molecules;  Each formula is integrated into the surface of the lens.  These molecules constantly and smoothly calibrate so the optimal amount of light reaches your eyes whether you’re in bright sunlight, under cloud cover or indoors.
