♦ Polycarbonate lenses are more durable than regular plastic, very lightweight.shatter-proof.
♦ Polycarbonate lenses are also shatter-proof, have the best impact resistance of any lens material. Many eye doctors choose to use only polycarbonate lenses for children's glasses. Since the lenses are shatter-proof, a child's eyes won't be damaged by shards of flying glass or plastic if the glasses are hit hard by a ball or a bat.
♦ They also have built-in ultraviolet (UV) protection to protect the eyes from the sun's harmful rays.
♦ Safety sports frames are made to hold up to high impact from fast-moving balls or heavy racquets. Polycarbonate will reduce injury from the frames themselves.
Progressive lenses address separate visual needs in one lens – usually with a "distance viewing" field build into the upper portion of the lens and a "near vision" field built into the lower portion. Rather than a line separating these areas, they are "blended" together, often with the middle portion of the lens serving as intermediate vision correction when necessary.
