PeakVision Sports is introducing a line of high performance sunglasses designed specifically for golfers, featuring what the company says are 100 percent distortion-free lenses. PeakVision said its Dual-Zone lenses feature neutral-density gray tinting in the upper zone that reduces glare and allows for accurate distance perception.

The amber-tuned color in the lower zone, according to the company, highlights the contours of the green for better reads of putts than with the naked eye. Incorporating these two filters into one lens, PeakVision said, creates optimal visual acuity.
