With a new pair of stylish shades, people with colorblindness are beginning to see the world just as the rest of us do. The corrective glasses were actually created as tools to detect blood oxygenation and flow beneath the surface of the skin. But then colorblind people started trying them on, and they began to see the world in a whole new way.The glasses were created by 2AI Labs, a company co-founded by evolutionary biologist Mark Changizi when he left Rensselaer Polytechnical Institute in New York. At 2AI, Changizi continues to conduct research, investigating how the brain processes visual information and searching for the answers to questions such as why we see color and what sort of tricks occur in the brain to create optical illusions.
Last summer the Boise, Idaho-based company developed three pairs of glasses called O2Amps. Special filters in the lenses either amplify the perception of blood oxygenation beneath the skin, blood concentration, or both. In this way the glasses allow users to detect emotions more clearly. Hospitals are already conducting trials with the glasses that can help nurses spot veins – many of us know firsthand how difficult, and painful, locating veins can be. They could also serve as a kind of frontline lie detector for police officers and security guards.\
