Abstract
An eyewear may include a lens and first and second temples individually removably attachable to opposite ends of the lens. The eyewear may include an attachment mechanism coupled to each of the temples, which includes a tab portion, a lever portion, a magnet attached to one of the tab or lever portions, and a magnetic material, which may be another magnet or a ferromagnetic material, attached to the other one of the tab or lever portions. The magnet and magnetic material are arranged on opposing sides of the tab and lever portions to urge them in a first direction towards one another. A carrier may be attached to each of the first and second end portions and may be configured to position the tab and lever portions on opposite sides of the lens as well as to constrain movement of the tab portion along a direction opposite the first direction.
