ABSTRACT:
A universal eyeglass attachment includes a docking head which is removably attachable to a frame of primary eyeglasses. A clip or coupling is attached to auxiliary eyewear and configured for connection to the docking head so as to removably attach the auxiliary eyewear to the primary eyeglasses. The clip or coupling is preferably pivotally attached to the auxiliary eyewear to enable a user to selectively move the eyewear away from lenses of the primary eyeglasses. Swing-arm locks can be incorporated to strengthen the frictional engagement fit between the auxiliary eyeware and eyeglass frame.
