Abstract: Glasses comprising a frame configured to secure a subframe such that subframe is substantially hidden behind the frame when the glasses are viewed from the front. The glasses may be part of a glasses set comprising a plurality of subframes and a plurality of pairs of lenses permanently fixed to the subframes such that another pair of lenses is chosen by exchanging one of the plurality of subframes for another one of the plurality of subframes. Alternatively, the glasses set may comprise a subframe and a plurality of lenses such that another pair of lenses is chosen by detaching the subframe from the frame, exchanging one of the plurality of pairs of lenses for another one of the plurality of pairs of lenses, and attaching the subframe back to the frame.
