Polarized glasses filter the specific light waves that cause glare. While reflective surfaces give off horizontal light waves, polarized lenses allow only vertically polarized light to reach the eye. This reduces glare while enhancing detail. Polarized filters are comprised of a chemical film that is applied to the surface of the lens. The filter contains molecules that are horizontally aligned, thus absorbing horizontal light waves while letting vertical ones pass through.

Polarized sunglasses also offer the important benefit of protecting eyes from ultraviolet (UV) rays. These rays come in three kinds: UVC, UVB and UVA. The ozone layer blocks most UVC rays, but UVB and UVA reach Earth's surface. UVB rays may cause pinguecula, a yellowish growth on the whites of the eyes and pterygium, a growth that can cover the cornea. Another complication is photokeratitis, a painful inflammation of the cornea. UVA rays are linked to cataracts and macular degeneration. Since UV rays pose a serious threat to eye health, using polarized sunglasses that offer 100% UV protection is imperative.

i-gogs Polarized sunglasses are made with TAC Polarized Lens technology. Triacetate Cellulose or TAC Polarized Lens is a new lens technology formulated for superior visual and polarization clarity. They are hard coated to resist scratching and block out 99% of all harmful UV rays up to 400 nanometers. These lens are very lightweight and highly impact resistant.

The benefits of wearing polarized glasses are the elimination of annoying glare, reduced strain to the eyes, improved depth perception, and accurate color recognition. Polarized lenses serve a purpose in every outdoor activity from the extreme athlete to recreational outdoorsman to weekend warriors. i-gogs Polarized glasses bring the best of protection and performance with outstanding value and quality.
