Claim 1
Independent Claim
246 words
An eyeglass structure comprising a rear frame structure including a pair of circular portions connected by a nose bridge and a pair of temple supports and means for attaching them to the outer edges of said circular portions, each circular portion having an annular outwardly extending peripheral ridge adjoining the front edge thereof, a pair of substantively identical front portions each having an opening therein coordinated with the opening in one of said circular frame portions, at least the rear portion of the opening in each front portion being circular and having an annular recess in the wall thereof for removably receiving one of said annular ridges to rotatably secure the front portion to said frame, each of said front portions having similar outwardly extending elements on opposite sides thereof to overlie a portion of the nose bridge and temple attaching means, the configuration of said front portions and outwardly extending elements being coordinated with the configuration of said rear frame structure and completely overlying and covering said rear frame structure and said nose bridge and temple supports to produce the effect of a unitary structure when said front portions are in selected adjusted positions relative to said rear frame structure with said elements overlying said nose bridge and temple supports and light modifying lenses carried by at least one pair of said portions whereby said elements when in said selected positions, position said light modifying lenses in the desired relationship for cooperation with the eyes.
