TAC sunglasses are specialized eyewear that have been styled after military glasses. These sunglasses are predominantly used by people who are attempting to enhance visual clarity. Tactical sunglasses are made from lenses crafted to augment color perception and make it easier to identify specific objects. The lenses are also polarized to reduce glare and other light noise that can obscure your field of vision. This polarization also keeps the eyes safe from the impact of UV-A and UV-B rays, which have been shown to cause conditions like cataracts.
