A community portal about Color blindness with blogs, videos, and photos. According to Wikipedia.org: Color blindness, or color vision deficiency, in humans is the inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. The English chemist John Dalton in 1798 published the first scientific paper on the subject, "Extraordinary facts relating to the vision of colours", after the realization of his own color blindness; because of Dalton's work, the condition is sometimes called Daltonism, although this term is now used for a type of color blindness called deuteranopia.
Zurich based Media Atelier today is proud to introduce Retina 1.0, their new color blindness helper for iPhone devices. Designed specifically to take advantage of the iPhone's unique capabilities and peerless interface, Retina helps color-blind users recognize colors by using the device's camera preview. By simply pointing the camera preview on any object, Retina provides a simple method to differentiate colors in a fast, efficient way.
Researchers from the University of Washington and the University of Florida cured color blindness in two squirrel monkeys with an injection of cells, they reported in the journal Nature. The results encourage scientists not only because color blindness affects 3.5...
LiveScience.com - Monkeys once color-blind can now see the world in full color thanks to gene therapy. The results demonstrate the potential for such methods to eventually cure human vision disorders, from color blindness to possibly other conditions leading to full blindness.
Scientists cast a rosy light on the potential for gene therapy to treat adult vision disorders involving cone cells -- the most important cells for vision in people. Scientists used gene therapy to cure two squirrel monkeys of color blindness -- the most common genetic disorder in people.
Color-blindness Cured by Gene Injection in Monkeys: "A simple injection of cells has cured monkeys of color-blindness—giving a green light to future research into improving human vision with gene therapy, a new study says."
While screening tests can only find out a color vision problem, detailed quantitative tests can determine its severity. During a comprehensive eye exam, you will always receive the Ishihara Color Vision Test for color blindness test, which is the most widely applied screening test invented by the Japanese ophthalmologist Shinobu Ishihara. The booklet of the test consists of typically 38 plates of many dots of various colors, brightness and sizes. Normal people can see clear numbers through these dots, which is beyond individuals with color blindness. Other abbreviated versions of this test comprise only 14 or 24 plates. For further color blindness test, a ...

Researchers from the University of Washington and the University of Florida used gene therapy to cure two squirrel monkeys of color blindness — the most common genetic disorder in people. Writing online September 15 in the journal Nature, scientists cast a rosy light on the potential for gene therapy to treat adult vision disorders involving cone cells — the most important cells for vision in people. "We've added red sensitivity to cone cells in animals that are born with a condition that is exactly like human color blindness," said William W. Hauswirth, Ph.D., a professor of ophthalmic molecular genetics at the UF College of ...
