What makes Sun Tiger ^® so great?

Simply put...SunTiger eyewear protects your eyes from damage caused by sunlight, while enhancing your vision!
SunTiger^® , Inc. was the original manufacturer of ultraviolet and blue light blocking sunglasses.  The technology is so unique that it holds four United States and International patents:

Sunglasses with these lenses not only protect your vision from all  the sun's harmful radiation, they actually enhance your vision enabling you to see more clearly in normal, foggy, hazy, or cloudy sunlight conditions.

SunTiger is a spin off company from NASA.  SunTiger sunglass lenses evolved from a technology developed by NASA scientists and engineers.  Almost two decades ago, NASA scientists began researching the superior vision of eagles, falcons, hawks and other birds of prey.  They discovered that these birds secrete an orange colored retinal fluid that absorbs harmful ultraviolet, and shorter blue light wavelengths, giving the bird's eyes protection from bright sunlight while enhancing contrast.

Through this research scientists developed an organic dye that has beneficial effects for human vision when incorporated into a sunglass lens.  This revolutionary technology led to the development of the SunTiger and Eagle Eyes lenses.

For many years doctors have been warned about the hazards of UV and blue light in regard to cataract formation and macular degeneration of the retina.  SunTiger Avian and Eagle Eyes lenses block 100% of harmful ultraviolet and blue light, providing extra protection for the eyes.

Three major organizations in the United States - The National Society to Prevent Blindness, The American Optometric Association, and The American Academy of Ophthalmology have formed a coalition called "Prevent Blindness" and published a paper called "Ocular Ultraviolet Radiation Hazard in Sunlight."  This coalition was formed to educate optical professionals and the public alike that UV absorption by the eye contributes to age related changes in the eye and a number of serious eye diseases.

SunTiger^® lenses NOW SURPASS the requirements of the Prevent Blindness coalition and the proposed FDA regulation.

The SunTiger Avian^® 515 lens is an orange color filter which provides high visibility by selectively removing harmful ultraviolet and blue light.
Eye fatigue is greatly reduced, distant objects will appear sharper, clearer and more definite.  The SunTiger Avian 515 is recommended for Pilots and Target Shooters who require excellent definition and contrast.

The EAGLE EYES^® PST 475 lens is a brown amber color filter with polarization to dramatically reduce glare caused by water, snow, ice, clouds, highway or other reflective surfaces.
The result is a soothing lens which reduces eye strain.  These lenses filter out all the harmful UV and blue light, yet maintain brightness to help minimize dilation of the pupils.  The result is brighter, sharper vision with maximum sun protection, while enhancing contrast and image definition.  This next generation of sunglass lens is in fact the best lens available anywhere in today's market.

Some of the many people wearing SunTiger ^® sunglasses include:  astronauts Alan Shepard, Buzz Aldrin, Pete Conrad, Wally Schirra, Jim Lovell, Russ Schweickart, Stephen Trippel, Charles Duke and Rick Hauck;   sailing champions Peter Isler and Dennis Connors; prominent Americans Ronald Regan, George and Barbara Bush; and athletes Bruce Jenner and Terry Pendleton.

  Doctors and scientists recommend SunTigers^® for eyesight protection. Sports enthusiasts, pilots, hikers, skiers and automobile drivers recommend SunTigers for increased visual acuity, improved distance vision and reduced eyestrain.
