Abstract: An eyeglass device includes a frame supporting first and second lenses therein. The frame includes support hooks and latch assemblies that permit the securing of third and fourth lenses to the frame over a respective first and second lens. Alternatively, an auxiliary frame is fastened to the frame using securing members attached to the auxiliary frame, the frame, or both the auxiliary frame and the frame.

Abstract: An eyeglass frame having removable lenses comprising of lens rings which are split into an upper and lower ring portion. Interposed between the upper and lower ring portions, and forming an integral part of the frame are positive actuating means to force open or draw closed the split lens rings to facilitate insertion and removal of lens. Several species of eyeglass frame are visualized. The preferred species utilizes a turnbuckle arrangement or a coupling post. Other species visualized are torsional spring action closure, helical spring action, and double loop retention.

Abstract: An eyeglass frame having removable lenses consisting of lens rings to which are secured movable upper or lower lens hooks receiving a removable lens. The frames may be utilized for interchangeable prescription, non-prescription, safety glasses and sunglasses. Movable upper or lower hooks complete the retention means for retaining the lenses in the eyeglass frame. Nine species of movable upper or lower hooks are visualized. The preferred species is a rotatable hook. Other species visualized are spring loaded projection, frictional slide projection, a projecting tilt arm, and screwable hooks.

Abstract: An eyeglass frame having removable lenses consisting of lens rings to which are secured fixed inner, upper, and lower lens hooks receiving a removable lens. The frames may be utilized for interchangeable prescription, non-prescription, safety glasses and sunglasses. A movable temple lens latch completes the retention means for retaining the lenses in the eyeglass frame. Five species of temple lens latches are visualized. The preferred species is a tiltable catch. Other species visualized are spring loaded projection, frictional slide projection, a swing projecting arm, and detachable retention pins.

Abstract: An eyeglass frame comprising two lens rings and two temples, the frame being supported and reinforced at the point of engagement of the temples and the lens rings by a loop or series of loops extending from the side of the eyeglass frame. The loop or loops that contact the outside portion of the temples is rigid enough to support and reinforce the junction of the lens ring and temple yet is pliable enough when heated to allow adjustment of the eyeglass frame to comfortably fit a wearer.
