DUAL-ZONE TECHNOLOGY

The Science Behind Dual-Zone™ Light Management

As illustrated (right), the bright sky generates over 80,000 LUX units. Simultaneously, the turf reflects only 4% of the ambient light. Solid-tint lenses (amber or gray) cannot optimize vision across these lighting extremes. That's why most golfers wear standard sunglasses on their hats - they can't see effectively!

Patented Dual-Zone™ light filtration integrates two unique filters in the lens.

• 20% transmission gray Upper Zone manages overhead glare while maintaining accurate distance perception.
• 60% amber Lower Zone spectrally increases contrast. On the green, this helps you read topography & grain better.

Sports Vision Research shows that with Dual-Zone™, speed-of-perception and visual acuity are enhanced...while visual stress and eye-fatigue are dramatically reduced.

Wouldn't you like to feel this relaxed after 18 holes?

Lens Distortion

Optical distortion interferes with high-performance golf.

PEAKS™ Dual-Zone / Zero Distortion™ Lens Technology

• No bi-refringent distortion (As shown, upper right)
• Reduced Chromatic Aberration (Lens Clarity, high 45 abbe value)

Polycarbonate lenses exhibit significant optical errors

• Bi-refringence (Appears as rainbows shown at lower right)
• Chromatic Aberration (Lens Haziness, poor 28 abbe value)

Which lens would you trust your game with?

DANGER - Ultraviolet Radiation

In a 2006 study conducted at the University of Utah, 52 golf professionals were evaluated for UV-related eye disease.

In the study's population of professional golfers, the incidence of sunlight exposure related eye disease were alarming:

• 51% had some form of UV eye disease
• 48% had pterygia (shown above right)
• 400% increased prevalence of pterygia compared to the general population
• 4 to 26 times as likely to develop some form of UV-related eye disease as the general population.

With PeakVision® lens technology, golfers benefit from the advantages of improved vision as well as 100% UV400 protection.

Golf Sunglass Preference Research

In on-course testing* of 158 avid golfers, PEAKS™ were preferred hands-down:

• 73% could see better with PEAKS™ compared to the naked eye;
• 74% could see better with PEAKS™ compared to Brand "O";
• 73% could see better with PEAKS™ compared to Brand "SB".

This independent research shows that 3 out of 4 golfers prefer PEAKS™. Most impressive, not one of the 158 thought they could see better with any other sunglass or even with their natural eye compared to PeakVision®.
