Ophthalmic lens laboratories face growing consumer demand for value-added features such as progressive bifocal and trifocal lenses; thin-profile, high index and aspheric lenses; and lenses with anti-reflective and anti-scratch coatings. The trend in lens materials has also moved from glass to polycarbonate, hard resins and high-index plastics. Although these materials are lighter than glass, they offer significantly better impact resistance. However, as they scratch more easily than glass, many require hard coatings.  Typical lens manufacturing processes include the following: generating/grinding; fining/polishing; edge grinding and cleaning prior to coating.
