An improved ophthalmic mounting arrangement for a pair of removable eyeglass lenses is described. The outer periphery of a lens-receiving annular liner exhibits a U-shaped channel which interlockingly engages a flat peripheral edge of an associated lens mounting rim in a rigid, unitary bifurcated frame. The two mounting rims of the frame are unobstructedly connected through an open bridge area whose lower peripheral edge is resiliently deformable out of the plane of the frame to facilitate insertion and removal of the lenses.
