Abstract
A construction for eyeglasses provides a frame with a first rim for securing a first fixed lens, a second rim for securing a second fixed lens, a first temple hinge for pivotally joining a first temple arm to the first rim, a second temple hinge for pivotally joining a second temple arm to the second rim, and a pair of double-knuckle hinges for joining pivotally joining a first selectable lens and a second selectable lens to the frame. The double knuckle hinges allow the first selectable lens and the second selectable lens to rotate 270 degrees, switching between a storage configuration and an active configuration. In the active configuration the selectable lenses overlap the fixed lenses in order to provide additional desirable properties. Thus the selectable lenses can be used in combination with the fixed lenses to act as bifocal glasses.
