ABSTRACT Eyeglasses which enable the lenses to be replaced quickly are provided. The glasses have a frame consisting of two loops each having several spaced clips within which the lenses can be retained. The frame loops are joined together by a bridge. A spring loaded slide is received in the bridge, the slide having hooks which attach over the upper edges of the lenses. The slide can be pushed upwards against the force of the spring to free the hooks from the lenses, allowing the lenses to be removed.
