These are the polarized bifocal sunglasses that eliminate the need to wear sunglasses over reading glasses or bifocals. The scratch-resistant polycarbonate lenses reduce glare and block 100% of harmful UVA, UVB, and UVC waves and their brown tint improves contrast in full sun, overcast, or hazy conditions. The bifocal reading panel is on the back side of the lens, so the glasses are indistinguishable from normal sunglasses. The wraparound frame is made from strong, flexible, lightweight TR90 grilamid nylon. Includes crush-resistant case. Black. Lenses meet ANSI standards for impact resistance. Specify reading strength: +1.5, +2.0, or +2.5. Not available for shipment in New York.
