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.
