• Standard Plastic - Plastic is lightweight and more impact resistant than glass but it scratches easily.

  • Polycarbonate - Polycarbonate, a plastic, is the most impact resistant material available for glasses. Polycarbonate is UV resistant and about 50 times stronger than other lens materials.

  • Glass - Glass is scratch resistant and provides the clearest possible vision. It is heavier than plastic, but is the most durable lens on the market.

  • High Index Plastic - Lenses correct vision by bending light as it passes through the lens. High index plastic lenses are able to bend light more than the conventional plastic used for lenses. This means that high index plastic lenses are thinner and lighter than conventional plastic lenses.

  • Trivex - Trivex is a high impact lens with optical qualities closer to glass lenses. It has an index of refraction of 1.53, the same as glass or standard plastic so high prescriptions will be thicker. Trivex Material has UV protection built into the lens.
