Polar Optics Black Unisex Clip Ons with Case

These sunglasses clip on to your own prescription glasses or readers. It’s so much easier and less expensive than buying that second pair of prescriptions! The clip ons are adjustable; see photo. They clip along the sides of your frames. Size ranges from 5 to 5.5 inches across. Each lens measures 1-1/4 by 2-5/16 inches. The shape is kind of a rounded rectangle. The case is in good used condition. See photo. It is very clean inside and out.
