The American brand Eagle Eyes utilises a certified, polarised lens system; the result of years of research and development. The origin of Eagle Eyes began at NASA's Jet Propulsion Laboratory where scientists developed ground-breaking technology that would protect human eyesight from the harmful effects of solar radiation light. The lens created by NASA resulted in Eagle Eyes which has earned official recognition from the Space Certification Program and is the only sunglass lens to receive the Lifetime Certified Space Technology™ seal of approval and the only sunglasses inducted into the NASA / Space Foundation Technology Hall of Fame. Eagle Eyes lenses block out 99.9% of harmful UVA, UVB plus scattered blue light. Featuring superior polarising capability, contrast filtration and anti-scratch coatings to both sides of lenses. Supplied with a soft carry pouch and hard case - excellent value for money.
