Abstract
The clip-on lens assembly has a pair of lenses connected together by a uniquely shaped, spring-biased nose bridge wire that has a profile that substantially matches the profile of the nose bridge portion of a pair of eyewear. The bridge wire is connected to either the rear or front surfaces of the lenses and doubles-back on itself before forming a bridge portion, which may include curling over from the front surface to the rear surfaces of the lens. The lenses may be tinted for use as sunshades or could be also optically enhanced for use as an auxiliary corrective lens. At the outer edges of each lens is a pair of hooks used to retain the clip-on lens assembly against a pair of eyewear.

Clip-on glasses for a pair of eyewear, comprising:
- a right lens and a left lens, each lens having first surface, a second surface, an inside edge and an outside edge, respectively;
- a bridge wire connecting the right lens to the left lens;
- said bridge wire having a left mounting point and a right mounting point connected to the first surfaces of the left lens and right lens respectively;
- said bridge wire depending from the left mounting point and right mounting point and doubling-back on itself prior to forming a bridge between the right lens and the left lens;
- said bridge wire spring-biasing the right lens and left lens inwardly towards each other;
- and
- means for retaining the clip-on glasses to the pair of eyewear.
