Abstract
Eyeglasses comprise a primary frame and an auxiliary frame detachably secured to the primary frame by interaction of magnetic members on the frames. The frames and magnetic members are configured to maintain the frames in a first orientation in which the auxiliary frame overlies the primary frame and a second orientation in which the auxiliary frame is disposed above and away from the optical axis of lenses carried in the primary frame.
