Scratch resistant sunglasses produced by NASA spin off tecnology. The DiamondHard® technology involves coating the lenses with a film of diamond-like carbon (DLC) that not only provides scratch-protection but additionally reduces surface friction, so that the lenses shed water more easily to reduce spotting. The film coatings are supplied by Diamonex Optical Products Group, Allentown, Pennsylvania, which employs a modified version of a dual ion beam bonding process originally developed by Lewis Research Centre.
