Abstract
A clip-on lens for selectively covering a lens of a pair of eyeglasses. The eyeglasses include first and second transparent lenses. Each lens includes at least two holes extending therethrough. Also included is a first and second extension arm, a nose bridge and a plurality of ferromagnetic studs. Each stud extends through a respective hole in the first and second lens for connecting the first lens between the first arm and the nose bridge and the second arm and the nose bridge. The clip-on lens includes at least two holes extending therethrough which are substantially aligned with the holes in a respective one of the transparent first and second lenses. Magnets are positioned within the at least two holes in the clip-on lens. Upon positioning the clip on lens against a respective one of the first and second transparent lenses, a magnetic coupling is formed between the magnets and respective ferromagnetic studs thereby selectively holding the respective one of the first and second transparent lenses. The clip-on lenses have a size and shape substantially similar to a size and shape of said first and second transparent lenses. Additionally, the clip-on lenses cone in various tints.
