Visiball V700 Golf Vision System (VB003)

Interchangeable lenses and an ingenious quick-change mechanism make it easy to turn this single wraparound frame into four pairs of glasses — each with a performance-enhancing function to help golfers save strokes. The patented Visiball™ lenses block out background colors so the light reflected off a white golf ball stands out — making your "lost" ball seem like it's glowing under a black light! Special green-reading lenses reduce contrasts to make it easier to see contours and to judge breaks. And there are two pairs of sunglass lenses — one for bright days; the other for low-light conditions. Everything fits neatly into a protective case that clips to your bag. 60-day warranty.
