Polycarbonate and Trivex lenses are special high index lenses that offer superior impact resistance. These lenses are up to 10 times more impact resistant than regular plastic lenses, making them an ideal choice for children’s eyewear, safety glasses, and for anyone with an active lifestyle who wants a thinner, lighter, safer lens.
Trivex lenses may be slightly thicker than polycarbonate lenses, but they provide comparable impact resistance and, like polycarbonate lenses, they block 100% of the sun’s harmful UV rays.
Progressive Lenses allow multiple vision fields to be incorporated into a single lens without any clear distinction between the fields themselves.
