    Polycarbonate lenses are about 10 percent thinner than Trivex lenses because polycarbonate usually has a high index refraction than Trivex. On the contrary, trivex lenses are about 10 percent lighter than polycarbonate lenses.

    Polycarbonate lenses are available in a wider variety of lens designs than Trivex lenses. Trivex lenses have a higher Abbe value and may produce sharper peripheral vision with less chromatic aberration than polycarbonate lenses. Trivex lenses have less internal stress and may produce sharper central vision than polycarbonate lenses.
