Some sunglasses give the appearance of good eye protection merely because they are dark; however, don’t let dark lenses be the deciding factor if you are looking for maximum eye protection.

The Blue Stille sunlgasses go beyond most ordinary sunglasses in the marketplace. Our certified, award-winning TriLenium™ polarized lenses offer Broad Spectrum Polarization™ developed from original NASA optic technology. This space-transfer technology is specifically designed to block out 99.9% of the sun’s vision-destroying light (UVA, UVB plus blue and violet light); and allow in vision-enhancing light rays (green, yellow, orange, red) and provide approximately 22% light transmission across the visible spectrum from 400-650nm (nanometer). The result? Superb protection, contrast, clarity, and definition – Guaranteed!

Some individuals are used to wearing dark tinted sunglasses for style or because they feel that the darker the lens, the more protection they are getting. But don’t let “just color” be the deciding factor in making your choice for good eye protection. Darkly-colored lenses may offer little protection – sometimes no – eye protection, and can actually darken and blur your vision, making it hard to see.

The Blue Stille sunglasses special lens filter provides you with a whole new view of your world and its surroundings! You’ll notice an exceptionally clear distinction of clarity, contrast and definition - beyond ordinary sunglasses. Your eyes become immediately relaxed with no need to strain or squint.

The lenses are made from polycarbonate and a material known as tri-acetate cellulose.

To help maintain your eyewear, never expose lenses to extreme heat and humidity (i.e. the dashboard of your car). Always store your glasses in a cool, dry place and in your Carry Case. To clean lenses, blow lightly to remove any loose particles or dust. Lightly spray with Lens Cleaner and wipe lenses gently in a circular motion with our micro-fiber cleaning cloth. It is very important not to over-rub lenses and not rub completely dry lenses. Harsh chemicals, non-microfiber and paper cloths, hair spray, cosmetics, salt and perspiration can all degrade lenses and/or lens coatings. Do not place your sunglasses face down on any surface to avoid scratching.

The origin began with initial research conducted at NASA. When America’s space programs began, NASA had to figure out a way to protect the eyes of astronauts while they worked in space. Independent studies by NASA’s JPL scientists revealed that the eyes of eagles and other birds of prey contain special oil droplets that selectively filter out harmful light; while allowing in other light rays, which explained the reason why these remarkable birds can distinguish small prey – even from miles away. This same selective- filtering capability was later duplicated into what is now known as Eagle Eyes® TriLenium® Polarized Lens Technology with Broad Spectrum Polarization.

TriLenium® Polarized Lens Technology was based on years of scientific research. Recommended and worn by board certified ophthalmologists, pro-sports figures, celebrities and American astronauts, it was certified in 2007 by the U.S. Space Foundation as the ONLY sunglass lens certified by this prestigious organization. Look for the Space Foundation Seal – found ONLY on Eagle Eyes TriLenium® Polarized Sunglasses – your guarantee of maximum protection and vision enhancement.

In 2010, Eagle Eyes’ technology, along with NASA, received further accolades by being inducted into the Space Foundation Technology Hall of Fame Award. A prestigious panel of judges from across the world spent painstaking hours and months reviewing the studies, the modes ofaction our lens technology holds, the patents upon which they were based, and several other critical factors that gained Eagle Eyes this most honorable induction. In fact, Eagle Eyes is the 62nd inductee into the Space Foundation Technology Hall of Fame and is honored along with such well-known space-transfer technologies as Lasik, TempurPedic and the DeBakey Blood Pump.
