Product Description
HELLO , I AM A LENS. WHAT CAN I DO FOR YOU?
1.74 lens material provides the world's highest level of ultra-thin lenses.
The first plastic eyeglass lenses were developed in the 1940s. These lightweight alternatives to glass lenses were call CR-39 plastic lenses. Plastic eyeglass lenses are about half the weight of glass lenses. They are relatively inexpensive and have excellent optical qualities. They also are more impact-resistant than glass lenses.
