A prescription lens attachable to a safety glass frame. The safety glass frame is provided with a single lens, a center cross pin and indentation on an inner surface of the safety glass frame juxtaposed the temple pivot pin. A prescription frame includes separate prescription lenses and a central clip that clips onto the cross pin of the safety glass frame. The outer ends of the prescription frame are provided with angular locking ends that are pressed into the indentation on the safety glass frame. Thus, the prescription lens frame is held securely onto the safety glass frame between the safety glass frame and the persons eyes. Damage to the safety glass lens or frame necessitate replacement of only the non-prescription safety glasses because the prescription frame can be removed from the damaged frame and secured to a new safety glass frame.
