High Index Lenses

High Index 1.74 Lenses Offered at RX-Safety

Stronger prescriptions have an obvious drawback: they require lenses that are fairly thick and heavy. The effect of these lenses is just as obvious. Distortion of the face and enlargement of the eyes are a common byproduct, resulting in a “Coke Bottle” look. This problem was even worse when glass was the only material from which lenses could be made; the advent of plastic helped somewhat but could not completely eliminate the problem. Even in plastic, the amount of material required to cut a strong prescription makes the lens relatively thick and heavy, and can impart a “bug eye” appearance.
