Abstract: A combined prescription lens and nose assembly is designed for securing to sport or safety glasses having an integral downwardly facing flange of inverted v-shape, or a separate flange secured to the glasses frame, for extending over a wearer's nose. The assembly includes a flexible nose bridge releasably secured to the flange to engage over a wearer's nose. Separate left and right prescription lenses are separately secured directly to left and right legs of the nose bridge so as to extend closely behind the left and right lens portions of the sunglasses. The lenses are each one piece, frameless members of transparent lens material and the lens material is secured directly to the nose bridge.

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.
