ABSTRACT:
A sun shade is provided for a pair of glasses including right and left hand panel structures for disposition immediately forward of the right and left hand lenses of the glasses and the panel structures are guidingly supported relative to each other for movement toward and away from each other. Biasing means is connected between the panel sections for biasing the latter toward each other and remote portions of the panel structure include upstanding, tensioned elastic members which may have their vertical mid-portions deflected apart by the temples of the associated glasses rearward of the pivot axes thereof and the upper margins of the panel sections include rearwardly projecting support flange sections for overlying the right and left hand portions of the associated glasses. The support flange sections support the weight of the sun shade from the glasses and the elastic members enjoy a non-slip frictional engagement with the glasses temples to not only prevent forward displacement of the sun shade relative to the glasses but to also exert inward biasing forces on the glasses temples rearward of the pivot axes thereof such that the grip of the temples on the head of the wearer of the glasses is increased to compensate for the additional weight of the sun shade supported from the glasses.
