Abstract

An interchangeable eyeshield system comprises a plurality of interchangeable, frameless lenses and a pair of bows releasably engaged to a selected lens. Each lens is of a different color matched to a corresponding weather condition. The bows are each engaged to the lens selected for wear by a clasp hingedly attached to the temple portion of each bow and an aperture within the lens to receive the clasp. The length of the bow is adjustable to accommodate the head size of the wearer.

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.

2. The eyeshield of claim 1 including a nosepiece removably attached to the interchangeable lens selected for wear.

3. The eyeshield of claim 1 in which the ear portion is longitudinal in part with a plurality of protuberances thereon and the temple portion is hollow for slidably receiving the ear portion, the temple portion having a plurality of holes for engaging the protuberances of the ear portion to frictionally connect the temple and bow portions together.

4. The eyeshield of claim 1 in which each lens is continuously curved beyond the range of peripheral vision when supported by the bows.

5. The eyeshield system of claim 1 including a portable pouch for carrying the interchangeable lenses.
