Patent abstract
Eyewear having a curved frame includes a protruding cover lens unit. The cover lens unit can be removably attached to the curved frame to position a less curved non-prescription lens in a protruding position with respect to the curved frame, thereby creating a space within the protruding lens unit. A prescription lens is removably attached to the curved frame and disposed behind the non-prescription lens. The prescription lens extends into the space without interference with the non-prescription lens.
