Lenses are made of hard plastic, instead of the glass used before.[citation needed] Plastics have good properties such as avoiding danger from debris, more accurate determinations (for refractive error), with a standard better than most glass. Lighter than glass lenses, can make lenses thinner depending on technique. There are different types of plastic. There are glasses with additional features such as scratch-resistant and UV-resistant. UV-resistant glasses are coated with a special substance that has a blue luster, which is better than glass or plastic-only glasses. The lenses are attached to the frame by a white wire, and the frame is secured in place by two screws.
