ABSTRACT:
The invention relates to a pair of glasses comprising an inner or lower pair of glasses for correcting vision deficiencies and an outer or upper pair of glasses that provides protection from the sun's rays. The outer pair is removably attached to the inner pair by means of inter-locking hooks having magnets, the inner pair having magnets located at the right and left intersections between the frame and the ear pieces. The outer pair of glasses comprises a corresponding pair of magnets located on the ends of inter-locking hooks at the right and left ends of the outer pair frame. When the outer pair and inner pair are assembled, the magnets hold the pair together by means of magnetic force while the inter-locking hooks provide additional strength and stability in the vicinity of the magnets, to allow the user more freedom to engage in activities and sports.
