In the 1990s, a scientist at Ames Research Center developed optical filters to block blue and green light, allowing other hues to stand out and making camouflaged objects more visible in forests. His work was later commercialized through a Space Act Agreement with NASTEK, which then partnered with Wheatridge, Colorado-based Optic Nerve Inc. to create a line of ski goggles that filter about 95 percent of blue light, giving professional and amateur skiers alike a clear view on the slopes.
