Glasses help colorblind people see normally.

A new type of glasses developed by 2AI Labs can help people with red-green deficiency to see colors more correctly. The glasses were initially developed as tools to help detect blood oxygenation and flow beneath the skin, allowing a nurse to more easily detect veins for an injection, for example. But when tried on by normally colorblind people, the company realized they could also help the 8 percent of men and 0.5 percent of women who suffer red-green deficiency.

One drawback of the glasses is that they may impair the perception of yellows and greens. As the company puts it, the glasses “spread the color confusion more evenly around the color-wheel, rather than having it concentrated only on red-green”. For this reason, the glasses should not be worn while driving, and are meant only as tools to be worn in certain situations.

Other interesting uses for the glasses in normal-sighted people include being able to easily identify emotions in others just by looking at them, using the glasses to identify color and flow changes in blood beneath the skin:

The O2Amps could help caregivers and police officers do their jobs better, help the colorblind to see reds and greens, maybe even make poker players better at calling someone’s bluff.
