| Abstract: |
The novel structure provides a prescription lens assembly that can be detachably mounted on a pair of sunglasses having a one-piece lens. The prescription lens assembly has an elongated flexible plastic support member having a groove formed in its bottom wall that mates with the top edge of the one-piece lens of a pair of sunglasses. The rear wall of the elongated support member has a recess formed therein that receives the top edges of the respective left and right prescription lenses and they are secured in position by a contact adhesive. An elongated cushion strip extends across the rear surfaces of the respective prescription lenses and functions as a cushion to absorb shock from impact and as a third contact point with the head to divide weight of the glasses so no single point puts undue pressure on the wearer.
