♦ 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.
A progressive lens is an amazing piece of engineering, allowing multiple vision fields to be incorporated into a single lens without any clear distinction between the fields themselves. The power in the lenses “progressively” changes from far-to intermediate to your full reading power.Progressive lenses are ideal for patients who have presbyopia.As we age naturally, our ability to see nearby objects and objects in the distance can decrease.
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.
