Comparative study of protective coating properties of CR-39-based spectacle lenses

Abstract This research aimed to study and compare the mechanical durability contamination resistance of organic spectacle lenses for everyday use, based on CR-39 poly(allyl diglycol carbonate) (PADC), from different manufacturers. The objects this are selected corrective three Each examined brand is represented by a reference uncoated lens other with types protective coating. sample has been characterized experimentally in our laboratory conditions according indicators surface: microhardness, roughness, wetting properties. results targeted eye specialists surface properties, essential daily usage spectacles, as well differences depending manufacturer.
