Traditional sunglasses marketed in the performance eyewear category are faced with a choice of which lighting condition to sub-optimize. No single lens color can simultaneously address the range of light conditions encountered in a typical day outside. Protection from glare caused by a bright sky, sunny or overcast, requires a darker lens filter. However, a dark filter dramatically reduces the visual cues from the surface environment. A typical green grass surface reflects only 2% of the ambient light. Other sunglass manufacturers address this problem with interchangeable lenses based on weather and lighting conditions. Unfortunately, this is not an effective solution as most athletes are not willing to change lenses in the middle of an activity.

Golfers are particularly impacted by the lens filter selected. While a gray neutral-density lens reduces the glare from overhead sun (or an overcast day as well), it filters out much of the visual information needed to see the contours of a green putting surface. An amber lens enhances a golfer's ability to visualize the variations on the green, however amber lenses tend to flatten distance perception and do little to protect a golfer's eyes from bright light.

"Have been wearing the glasses 100% of the time when outside. Wonderful!"
Jon J. - PGA Professional

"This is the best sunglass for golf I've ever seen. I wear them all the time and recommend them to everybody I know."
John S. - Dallas, TX

"It's like you're not wearing them, I forget I have them on. You can read your line so much better, but you have to believe what you're seeing. They are so comfortable and clear, I've never had a sunglass like this before."
Roger P. - Leawood, KS

"I have enjoyed my PeakVision for golf so much, it's amazing. My wife complains though, because I never take them off. Well, almost never!"
Eric C. - New York, NY

"Yeah, PeakVision is great for golf, but for long trips in the automobile they are just as good."
Lyle P. - Dallas, TX

"I have been wearing my Callaway Ray Bans for 4 years. After playing with PeakVision, I threw my Ray Bans away. I am so relaxed when wearing PeakVision. Best sunglass for golf I've ever worn."
Kevin A. - San Carlos, CA

"PeakVision is the first sunglass that doesn't interfere with my game, and still protects my eyes from UV. As a golf professional, this is extremely important to me."
David M. - PGA Professional

"It was very cloudy for the front nine, so I didn't wear them. I shot a 54. The sun came out very bright on the back nine, so I put my PeakVisions on. I was so comfortable and relaxed even though the sun was shining bright. Since my first outing, I have dropped an average of at least 6 strokes off my previous scores."
Kent M. - Overland Park, KS

"I love how clear they are. I've tried just about every sport sunglass there is and they all seem to blur my vision. PeakVision are just the best for sharpness and clarity."
Betsy V. - Tulsa, OK

"PeakVision is by far the best golf sunglass ever. I see everything I need to see for the golf game so much better than ever before."
Gordon R. - Blue Springs, MO.

"This is the first sunglass that I've worn which I didn't have to take off when I putt. They really help me maintain my ability to read the green."
Nick U.- Wichita, KS

"I just can't believe how relaxed my face becomes when I put PeakVisions on. And they are so lightweight that I forget I'm wearing them, even after 2-3 hours in the sun. For my game, it's the best I've ever seen."
Steve M. - PGA Professional
