IMPROVING PERFORMANCE ON THE TENNIS COURT
An aqua lens tint has long been the standard for enhancing yellow targets such as a tennis ball. Doc tweaked the conventional aqua tint to maintain the yellow ball enhancement but to also highlight the out of bound lines. This new Leverage Performance Tennis tint enhances the two most important targets for the tennis player. This fact alone would make this new tint a giant improvement over existing tennis tints, but Doc knew there was another problem to be solved. The sun can be blinding when looking into the sky with any selective filtration tint to enhance a yellow ball, after all the sun is yellow too, so Doc added a 12% light transmission gray gradient to the top 25% of the Leverage Performance lens. In straight forward gaze the eye is viewing through the wavelength enhancing portion of the lens and the ball and lines are enhanced. When the wearer looks up, as when serving or returning a lob, the view is through the dark gray tint. When the human eye is exposed to bright light photo receptors are bleached out and the recovery takes a short period of time. Testing of this revolutionary tint on tennis players, at all skill levels, proved that visual adaptation time is improve by 1 to 1.5 second resulting in vastly improved performance considering the speed at which a tennis ball travels.
SOLAR BAT® SELECTIVE WAVELENGTH FILTRATION TECHNOLOGY
Dr Gary Nesty called on his knowledge of optics and the human eye to design tints to enhance vision and thus performance in your chosen sport and outdoor activities.
PNVX OPTICS (PRESCRIBED NATURAL VISION EXTRA)
Doc knows how the human eye works and optically what is required of a sunglass lens to provide the wearer with unaffected depth perception and unrestricted peripheral vision. Maximum eye protection and visual performance is best achieved with a sunglass lens that wraps around the face. The trade off is that this lens design can adversely affect depth perception and constrict peripheral vision. Doc designed PNVX optics to maintain the advantages of a wrap lens while avoiding the disadvantages. Victory Series Leverage Series sunglasses have PNVX optics.
PNVXD OPTICS (PRESCRIBED NATURAL VISION EXTRA DEFINITION)
Doc is always searching for ways to improve the optics in Solar Bat® lenses. As soon as the PNVX optics were designed, Doc started the research and development of a second generation lens. He utilized lens curve and thickness variations to achieve even better visual performance. This second generation lens design was named PNVXD. Elite and Pro Series Leverage Tennis sunglasses have PNVXD optics with a hydrophobic coating on the lenses.
PNVX and PNVXD vs GLASS LENSES
PNVX and PNVXD lenses are 95% as scratch resistant as glass and are 20% the weight and 10 times more impact resistant. In 2012 less than 1% of the glasses prescribed by eye care professionals in the USA were glass lenses. Glass lenses are old technology. If you are still wearing glass lenses you need to jump into the 21st century with Solar Bat®.
Ultraviolet wavelengths are invisible to the human eye but nonetheless harmful. UV light causes sunburn, skin cancers, cataract, and macular degeneration to name the most recognized complications of prolonged exposure. The Solar Bat® lens material is a 100% UV screen. Your eyes and the skin around your eyes are protected from all harmful UV wavelengths.
A scratch resistant coating is applied to the entire lens and then reapplied to double the thickness of the coating. With normal care your Solar Bat® will give you years of service.
If the Leverage™ Performance tint does not improve your visual reaction time you can return the sunglasses within the first 21 days, in like new condition, for a full refund.
