With Puma full wraparound yellow lens bifocals, you can play golf, tennis, baseball, run, cycle, hike, drive or ride motorcycle and be able to read maps, scorecards, menus, GPS or smart phone without switching glasses! The Puma bi-focals also provide a full 180 degree wrap to block harmful UV rays, wind, dust and debris from all angles. Lenses are ANSI Z.87.1 safety rated polycarbonate lenses. Yellow glasses also known as night vision glasses are popular for night riding and night driving since yellow tint can reduce headlight halo effect at night. Yellow lens glasses are also great for cloudy days and raining days, too. Although perfect for men, the Puma is a slightly smaller frame and one of our most popular bifocals for women. Fits SMALL to MEDIUM heads - very versatile frame. Free Microfiber cleaning case included for each pair.
