In 1992, Optima Inc. introduced the first 1.66 high index plastic lens representing the "Next Generation" of high index lenses. The HYPERINDEX® and HYPERVIEW® 1.66 combine the benefits of ultra thin and ultra light lenses with superior optics. Computer-engineered aspheric lens designs eliminate peripheral distortion. An incredible 50,000 points on a lens are computer calculated and connected for smooth transitions throughout the entire lens surface. The optical qualities of 1.60, and the new thinner and lighter 1.66 high index plastic lenses, far exceed the optical qualities of earlier plastic lens materials. Now eyeglass wearers can experience the benefits of the thinnest and lightest lenses, with superior optical qualities that were previously only attainable with glass.

Optima offers 1.66 high index single vision lenses as well as a 1.66 progressive (no line bifocal) lens. Optima's HYPERINDEX® and HYPERVIEW® 1.66 (progressive or no line bifocal) lenses are up to 27% thinner and lighter than the previous standard, 1.60 lenses. And up to 50% thinner and lighter than conventional or ordinary plastic lenses.
