LENS MATERIAL

Polycarbonate lenses are detrimental to the game of golf. The manufacturing process used to create the majority of plastic (polycarbonate) lenses in today's sunglasses is 50 years old and produces lenses with significant birefringent optical distortion - sunglass haze. That's why you can't read the green (or your scorecard!) with most sunglasses. With PEAKS, you're getting a read you can trust from the 1st tee to the 18th green.
