Abstract

Apparatus 10 for modular eyeglasses having a plurality of lens members 14 that can be selectively mounted to a frame member 12. The frame member 12 has the typical temples 16 and a crossbar 18 with an interdisposed bridge 20. The bridge 20 is formed of pad arms and nose pads 36 depending from a mounting having a magnetic element 22 fixed within the top mounting surface with a pair of apertures 28 spaced away from each side of the magnet. The frame 12 provides means whereby a number of lens members 14, such as reading lenses, distance lenses and sunblock lenses can be easily mounted to a single frame. A lens member 14 is comprised of a pair of lenses 34 with holes drilled in them for attachment at 32 to a flanged lens platform 30. The platform 30 has a mating magnetic element 24 with posts 26 located on each side of the magnet linearly conforming to the distance between the frame housing apertures 28. Once the magnets 22, 24 are aligned the posts 28 and apertures 28 prevent torsional forces from displacing the lens member 10, while maintaining the correct spacing between the user's eyes and lenses 34.
