The Hemo-Iso O2Amps that amplify the natural ability to see changes in blood concentration...

Along with facial expressions, tell-tale variations in facial blood flow that causes reddening and whitening of the skin can also give an indication of people's emotions. To take advantage of this, 2AI Labs developed a special pair of glasses designed to enhance a person's color vision to better enable them to perceive the oxygenation and hemoglobin variations in another person's face, and thus their emotional state. The glasses are now finding a variety of applications, from medical to security.  Read More

EnChroma's Cx sunglasses are claimed to allow people with red-green color blindness to see...

While many people may think that being color blind means seeing everything in black-and-white, such a condition is in fact quite rare. Instead, the majority of people who are classified as color blind are capable of color vision, but they have difficulty distinguishing red and green as distinct colors. EnChroma’s Cx sunglasses are designed to help in these cases, by selectively reducing the transmission of given wavelengths of light, thus allowing red and green to stand out.  Read More

Best known for discovering security flaws in online systems, Dan Kaminsky has recently announced the development and release of a smartphone app to help with color blindness. DanKam takes the colors that cause viewing problems and applies filters to make them visible. The system is currently optimized for the most common form of color vision deficiency, although users are encouraged to customize and tweak the augmented reality app to try and find settings that work best for them.  Read More

When English chemist John Dalton first wrote about color blindness in 1798, he must have wondered how science would improve the quality of life for people living with the condition. Today, spectacles, contact lenses and revolutionary corrective eye surgery combat the effects of a myriad of vision disorders, yet people with color blindness still live in quiet acceptance of this common genetic disorder. Now researchers have delivered promising results by successfully treating two squirrel moneys with defective color perception using a gene therapy that could also safely eradicate color blindness in humans.  Read More
