TAC polarized lenses are thinner than ordinary PC or AC lenses, only about 0.74mm in thickness but more durable and flexible than ordinary PC or AC lenses. Normal sunglasses lenses can only reduce sunlight, but polarized lenses can reduce the glare from sunlight, especially the glare from the surface of roads, lakes, and windows. These rimless clip-on sunglasses are designed to fit over the Vuzix Blade and flip up when you don't need them.
UV-400 Lenses provide 100% UV protection and anti-glare from sunlight.
