I claim all modifications coming within the spirit and scope of the following claims:
1. An eyeshield system for shielding the eyes of a wearer, comprising:
- a plurality of interchangeable, frameless continuous lenses each of a color selected to be worn for a specific weather condition, each lens having a pair of apertures therein;
- a pair of bows for supporting the selected lens, each bow comprising a temple portion and an ear portion adjustably connected together to vary the length of the bow; and
- a clasp pivotally hinged to each bow for removably engaging each bow to the selected lens and sized to engage the corresponding aperture in the selected lens to enable the lens to be supported without a frame, the clasp having a base portin and a pair of resilient projections extending outwardly from the base, each projection having a barb formed therein, and each base portion having at least one elongate lens engaging member extending outwardly therefrom further than the width of the barb, said lens engaging member being laterally spaced from each barb a distance equal to the thickness of said lens so as to permit said lens to be securely engaged therebetween;
- said projections being squeezed together for insertion through the aperture, after which said projections move apart for affixing the clasp securely to the lens, the lens being engaged between each barb and lens engaging member so as to prevent the movement of said lens during use.
