Abstract
The clip includes a lens carrying member and a spectacle clamping member which are situated on opposite sides of a bifurcated support member. A single simple 'c' shaped spring retains the members together, urges the clamping member toward its spectacle clamping position and urges the lens carrying member toward either an operative position, where the sunglass lenses intersect the line of sight, or an inoperative position, where the sunglass lens are remote from the line of sight.
