<p>An eye glass assembly having a frame (12) with a rim portion (14) with an inner peripheral edge extending between the frame front side and the frame back side. Opposing surfaces of the rim portion define a groove (26) in the peripheral edge with the groove including a first annular rear retaining surface (26a) and an opposing annular forward retaining surface (26b) both generally parallel to a dimension extending between opposing surfaces of the inner peripheral edge. An eye glass lens (20) is sized to be received within the rim portion and has an outer peripheral edge sized to be received against the inner peripheral edge of the rim. A retaning ridge (32) is disposed on the outer peripheral edge of the lens and protrudes therefrom into the groove. The retaining ridge is provided with a first annular retaining surface (32a) and a parallel spaced apart second annular retaining surface (32b) which oppose the rear retaining surface and the forward retaining surface, respectively. The first and second retaining surfaces are both generally parallel to the dimension extending between opposing surfaces of the inner peripheral edge.</p> |
