ABSTRACT:
A shade attachment for eyeglasses includes a frame defining a pair of openings dimensioned for registry with lenses of a pair of conventional eyeglasses. Top and bottom resilient clips are provided on the frame and are configured for frictional engagement with top and bottom edges of eyeglass lenses. A set of transverse slats are mounted on the frame and extend across the lens openings. The salts are mounted for movement between open and closed positions by a linear drive train including a plurality of driven gears secured to axle shafts of each of the slats. A plurality of idler gears are mounted for rotation on the frame between and in mesh with each adjacent pair of driven gears. A drive gear is mounted for rotation on the frame and in mesh with one of the driven gears. A control knob is provided for manually rotating the drive gear to simultaneously open or close all of the slats extending across one of the frame openings. In a second embodiment of the present invention, the shade mechanism is provided as an integral part of a pair of eyeglasses.
