INTERCHANGEABLE TINTED LENS GLASSES

Abstract

An interchangeable eyeglass lens system allows for the placement and easy removal of lenses to a pair of glasses to create various shades and colors of sunglasses. The glasses may include a set of prescription lenses permanently fixed to the frame and a second set of lenses that slide into a groove in the frame. The present invention is further a method of interchanging the tinted lenses within the glasses.

DETAILED DESCRIPTION OF THE DRAWINGS

[0036] FIGS. 1-5 depicts an embodiment of the present invention 100. The interchangeable eyeglass lens system 100 includes a front frame 102, temple sidearms 103, and a pair of hinges 104 that connect the temple sidearms 103 to front frame 102. The interchangeable eyeglass lens system 100 further includes replaceable lenses 105. A pair of prescription lenses 106 may be installed in the front frame 102.

[0037] FIG. 1 is a perspective view of the interchangeable eyeglass lens system 100 with a pair of prescription lenses 106 in place.

[0038] FIG. 2 is top planar view of the interchangeable eyeglass lens system 100. Front frame 102 further comprises a nose piece 107 disposed centrally in the front frame 102. An interior eyeglass frame 108 is disposed closest to the users face and would in an embodiment include a prescription lens 106. An outer eyeglass frame 109 further extends from temple 110 to opposing temple 110. The outer eyeglass frame 109 defines a slot 111 for inserting the interchangeable lenses 112. Slot 111 extends from approximate the noise piece 107 to the temple 110 on the top frame face 113 and is discontinuous along the bottom frame face 114.

[0039] FIG. 3 depicts a front planar view of the interchangeable eyeglass lens system 100 with the prescription lenses 106 in place.
