SCRATCH-RESISTANT LENSES

While plastic eyeglass lenses offer a weight advantage over glass lenses, they are susceptible to scratches during everyday use. Scratches cause poor visual quality and annoying reflections. Fortunately, most eyeglass lenses sold today (including high-index lenses and lenses made of polycarbonate and Trivex) have a built-in scratch-resistant coating. For other lenses or those without scratch-resistant capability, anti-scratch coatings can be specified at the time of purchase. While an anti-scratch coating does not guarantee that lenses will not become scratched, it does decrease the likelihood substantially. Scratches are usually due to fine grains of grit that are ground into the surface of the lens while the dirty lenses are being wiped. Eyeglasses should be rinsed in water before wiping the lenses. Scratch-resistant coatings, ultraviolet light blockers, anti-reflectives, tints and edge treatments can be combined to meet your individual needs. To avoid scratched lenses, wipe your eyeglasses with a microfiber cloth after rinsing, and store them in a cushioned case.
