All eyeglass lens materials are not equal. Space age materials, computer-engineered lens designs, and improvements in older lens technologies provide distinct advantages for the eyeglass wearer. Lens materials like Optima's HYPERINDEX®, HYPERVIEW® and POLARTEC® high index plastic have superior optical advantages over other lens materials. Both 1.60, 1.66 and 1.67 high index plastic lenses combine the optical precision usually associated with glass, but their lighter weight make them a far better lens choice than polycarbonate unless impact resistance is the only consideration.

Glass lenses remain the least impact resistant and heaviest. Ordinary (conventional) plastic lenses are the thickest, although lighter than glass. HYPERINDEX®, POLARTEC 1.67 (polarized) and HYPERVIEW® 1.66 (a no line bifocal) represent the state of the art, combining both thinness and lightness with optical superiority. All provide the lens wearer with the thinnest and lightest lenses for the most dramatic improvement in appearance and comfort with advanced optics for the best vision.
