Our Opticians will recommend the best choice based on individual needs.

Lens MaterialsHARD RESIN (plastic)
Conventional hard resin lenses are half the weight of glass lenses and can be tinted to almost any color and density. Hard resin lenses are more easily scratched than glass but can have an optional scratch protection applied. They are more impact resistant than glass.

Modern technology has created lenses that bend light differently so that stronger corrections are thinner than when made in conventional materials. Such lenses are called "high index" producing stronger corrections that are more attractive because they are slimmer. High index plastic uses less material so they are often lighter in weight. High index lenses absorb all harmful UV light and can be tinted to any shade or color.

There are lenses that darken as you go from indoors to outdoors. They are available in glass, hard resin and polycarbonate. Originally made to darken to a moderate shade, new versions are available that darken to a true sunglass. Ask for a demonstration of these lenses.

Polycarbonate lenses are the most impact resistant lenses available and are always the lens of choice for young people and active patients. Polycarbonate lenses are high index and usually provide the lightest, most comfortable lenses. They absorb all harmful UV light and can be made ultra-thin because of their unique strength.

Lens MaterialsGLASS
For years, glass was the only lens material available and glass still offers superior optics. Although glass is the most scratch-resistant material, the primary disadvantage of glass is its weight, generally twice that of hard resin. Glass lenses are heat or chemically tempered to increase impact resistance but can be dangerous if they break. We are very selective as to who can wear glass lenses. We do not recommend fitting children with glass lenses as they can be a safety hazard.
