ABSTRACT:
A spectacle strap-on apparatus includes a pair of spectacles devised with a pair of lenses joined by a nose stand having two nose pads; and a pair of strap-on sunglasses. Wherein, the nose stand has auxiliary stands for connecting the two nose pads to the nose stand; and each auxiliary stand is provided with a fastening ring having a magnet inlaid at a center portion thereof. The strap-on sunglasses have a pair of lenses, and a nose stand connecting the two lenses. Wherein, the nose stand is fixed with a pair of fastening rings each having a magnet inlaid at a center portion thereof. Using the fastening rings of the strap-on sunglasses to adhere to the nose stand of the spectacles, the two magnets precisely come into contact with the two magnets at a rear portion of the nose stand of the spectacles, thereby firmly locating the strap-on sunglasses.
