Glass

Glass lenses are heavy, expensive, and the least safe of all lenses. Glass lenses are rarely prescribed now because more durable, lighter-weight lens materials are available.

Plastic

Plastic lenses are much lighter than glass and are much more impact resistant. Plastic lenses are more easily scratched than glass, but they can have an optional scratch protection applied. They can also be tinted to almost any color and density.

Hi-Index lenses (thinner and lighter)

Modern technology has created lenses that bend light differently so that stronger corrections are thinner than when made in conventional materials. These "high index" lenses are more attractive because they are slimmer. Also, high index plastic lenses use less material so they are often lighter in weight.

Aspheric Lenses

Aspheric lenses are excellent for the farsighted patient. The thickness of the center of the lens is reduced, making the magnification or "coke bottle" effect much less. Aspheric lenses provide less distortion and enhanced optics.

Polycarbonate/Trivex Lenses

Polycarbonate and Trivex lenses are the most impact resistant lenses available. These lenses are always the lens of choice for young people and active patients. They are light and comfortable at the same time while providing the utmost security for the active patient.

Bifocal, Trifocal and Progressive Lenses

Bifocals and trifocals offer near, intermediate and distance vision through 2 or 3 segments of the lens separated by lines. Progressives offer near, intermediate and distance vision correction with no abrupt changes or unsightly lines. The change in vision correction is much less noticeable and more gradual than with old style bifocals, hence the name "progressives".

Scratch Protection

Scratch protection is an extremely tough quartz coating applied to plastic and polycarbonate lenses to protect them.

Anti-Reflection Coatings

Anti-Reflection coatings are particularly effective for reducing eye fatigue for computer operators and anyone driving at night. Because the coating removes many distracting reflections, the glasses will not only look good through your eyes, but will also look good to the eyes of others.

Ultraviolet Coatings

Lenses like polycarbonate and high index types include built-in UV protection that blocks out harmful ultraviolet rays. For those lenses that do not include the built-in UV protection, an extra UV protective coating is applied.
