Scratch Resistant Coating (SRC)

Through all the advancements in eyeglass lens coatings, eyeglass lenses are still not scratch proof not even glass lenses. However, eyeglass lenses that are treated front and back with a clear, hard coating do become much more scratch resistant. Today, most types of plastic eyeglass lenses, which include high-index, polycarbonate Trivex and some traditional CR-39 plastic materials have a built in scratch-resistant coating. Scratch resistant coating on CR-39 regular plastic lenses is optional so make sure we know that you want scratch-resistant lenses in your prescription eyeglasses.
