Glasses for Color-blindness
Red-green color blindness is common, especially in males. A company called O2Amp developed glasses that improve the ability to see blood, and the amount of oxygen in blood, through the skin, which improves the perception of health and emotion. An accidental "side effect" of this technology was improved ability of people who have red-green color deficiency to differentiate those colors. There are 3 versions of the glasses, one of them, called Oxy-Iso, is especially helpful for color blindness. They are certainly not a cure but they do work and reviews are positive. They are available online for about $300.
