Abstract
The disclosure is of an eyeglass frame having two lens receiving portions each having an annular channel in which a circular lens may be mounted. The annular channel includes a rear wall which faces the wearer and a frant wall which faces someone who looks at the wearer of the frame. The frame includes an auxiliary wall which extends from the front wall of the channel and changes, for someone looking at the wearer of the frame, the circular appearance of a lens in the channel to another shape determined by the auxiliary wall.
