Polarized Lens Technology

Space Cert Slideshow Photos : 

NASA Jet Propulsion Laboratory scientists were investigating ways to protect human vision against various ranges of harmful radiation from the invisible and visual spectrum. They looked to nature for a solution. How do eagles and other birds of prey protect their eyes from high- energy sunlight they are exposed to on a daily basis? It turned out that eagles have droplets of oil in their eyes that filter out all harmful radiation. This filtering process dramatically reduces scattering of light and permits only those wavelengths of light to enter their eyes, which allow the eagle to have high visual clarity. NASA scientists and engineers decided this technology could be used to make sunglass lenses. They simulated natural droplets of oil and incorporated it into a sunglass lens that is now called Eagle Eyes.
