Abstract
A clip-on mountable on the frame of eyeglasses having a pair of optical visual-correction lenses. The clip-on is provided with a pair of filter lenses held together by a bridge, the filter lenses registering with the optical lenses to convert the eyeglasses into radiation-protection glasses, such as sunglasses. Anchored on the margin of each filter lens is at least one clip having a ledge at one end which supports the margin of the lens, and an arm at the other end that curves over the frame at the corresponding optical lens to retain the clip-on. Intermediate the ends of the clip is a transverse hook which engages the margin of the filter lens to resist dislodgment of the clip.
