I have heard that eyeglasses designed to help people with colorblindness. You just use a tinted lens in one of your eyes, usually in your non dominant eye, and that%u2019s it. In this case both eyes actually see different colors and because of that the brain can extract some other information out of certain colors. You can also use two different tints in each of your eyes. This depends very much on ones personal impression. But I am not sure where you can buy it. Maybe you can search them on Ebay. source: http://www.colblindor.com/2008/03/29/improving-color-vision-with-lenses-for-the-colorblind/
