Anti-Reflective Coating is a coating that can be applied directly to your prescription lenses. It has many benefits including reduction of eye strain during prolonged computer use, reduction of glare for night-time drivers, and reduction of white-light reflection on your lenses if photographed.
Polarized lenses are effective cutting strong light, reflection and scattering light. it makes messy rays become parallel. TAC polarized lenses makes the scenery more clear and soft. and polarizing angle radians are gone though professionally design and producing, The wearers have no distortion of scenery and the feeling of Vertigo.so it is great for golfing, driving, boating, cycling, and running.
Linearly polarized glasses
To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through orthogonal polarizing filters (Usually at 45 and 135 degrees). The viewer wears linearly polarized eyeglasses which also contain a pair of orthogonal polarizing filters oriented the same as the projector. As each filter only passes light which is similarly polarized and blocks the orthogonally polarized light, each eye only sees one of the projected images, and the 3D effect is achieved. Linearly polarized glasses require the viewer to keep his or her head level, as tilting of the viewing filters will cause the images of the left and right channels to bleed over to the opposite channel. This can make prolonged viewing uncomfortable as head movement is limited to maintain the 3D effect.
Circularly polarized glasses
To present a stereoscopic motion picture, two images are projected superimposed onto the same screen through circular polarizing filters of opposite handedness. The viewer wears eyeglasses which contain a pair of analyzing filters (circular polarizers mounted in reverse) of opposite handedness. Light that is left-circularly polarized is blocked by the right-handed analyzer, while right-circularly polarized light is extinguished by the left-handed analyzer. The result is similar to that of steroscopic viewing using linearly polarized glasses, except the viewer can tilt his or her head and still maintain left/right separation (although stereoscopic image fusion will be lost due to the mismatch between the eye plane and the original camera plane).
It is worth mentioning that Polaroid has 7 layers composite, which comply with the international sunglasses lenses standard, UV400 UV sunglasses lenses standard, the polarized lenses can fully protect eyes, the first layer is a polarizing layer, is the core of the lens, it provides more than 99% of the polarizing effect, which can effective absorption of glare. Second and third layer for bonding, can effectively resist the cutting, baking, baking bend, cut pieces, tests of withstand harsh environments. The forth and fifth layer for UV-absorbing layer, over 99% of UV-ultraviolet rays are absorbed. The sixth and seventh layer for shock-proof layer, it increase toughness, impact resistance, preventing lens scratches and extend the life of polarized lenses.
