ABSTRACT:
The disclosure is of a lens having a bevelled rim and a frame having a channel for receiving the lens and carrying a bevel which is complementary to the bevel of the lens. The lens also carries on its rim a plurality of wedge-like positioning members which grip the channel of the frame and essentially lock the lens in place so that it cannot rotate.
