Flip Up Skinny Rectangle With Polarized Lenses

Skinny curved rectangular shape flip-up with UV400 polarized lenses that clips onto prescription glasses. Polarized lenses are lighter weight and reduce the most glare. Flip-ups work best for glasses that closely resemble the shape of the flip-up. It also fits best if the frame is straight across the top so that when the flip-up clamps onto your glasses it is sitting straight across the top of your glasses. Measure your glasses width x height. It is best to add about 2mm's to the height of the flip up height to accommodate for how the flip up clamps onto your glasses. It is usually okay for the flip up lens to be a little wider or higher than your glasses, it will just overlap a little.
