The eyeglasses frame is provided with spaced engaging parts. The lens sections of the sunglasses are provided with an enclosed spring bridge mechanism that permits the lens sections to be moved toward each other, compressing the spring, to insert the sunglasses between the engaging parts. The spring urges the lens sections away from each other, to cooperate with the engaging parts, to mount the sunglasses on the eyeglasses frame.
