In general, a plurality of claw portions are projected on the frame of the sunglasses for apron in a hook shape, and the hook-shaped claw portions are used to grip the front frame of the corrective glasses. For this reason, the apron sunglasses cannot be swung up and used freely, and there is a possibility that the front frame of the corrective glasses may be deformed or the corrective lens surface may be damaged when the apron sunglasses are worn.

Some of these bifocal glasses have a flip-up mechanism. However, in the flip-up bifocals, the flip-up mechanism with a light control lens is directly provided on the front frame of the corrective glasses. Many. Therefore, even if the light control lens is retracted by flipping it up when the function as sunglasses is not needed for a long period of time, the state that the light control lens protrudes in the shape of an outline on the upper edge of the corrective glasses continues to be smart. In addition to lacking, there was a drawback that the center of gravity leaned forward and it was not comfortable to wear.
