Are you, or someone you know, color blind? Then these glasses would make a great holiday gift. Invented and patented by scientists from Princeton and Caltech, O2Amp Eyewear [$304] corrects and dramatically enhances retinal color perception. — What does that mean? Wearing these lenses means gaining a competitive edge in careers and activities where vibrant color vision is crucial to correct diagnosis. The Oxy-Iso was designed to amplify perception of the oxygenation signal coming from the blood under the skin, and is also used by color normal medical personnel for vein finding and assessment of health. It aids color deficiency because color vision actually evolved to see these oxygenation signals from skin, so as to sense blushes, blanches, etc.
