Color Blindness News and Research

RSS

Color blindness, or colour blindness, a color vision deficiency, is the inability to perceive differences between some of the colors that others 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.

Study finds 24% of Spanish drivers have some vision problem

One in four Spanish drivers has a vision problem that affects their driving ability. This is the finding of a study commissioned by the association Visión y Vida in collaboration with the RACC to Aurora Torrents and Jaume Escofet, professors at EUOOT. The aim of the study is to provide objective information on the eyesight of Spanish drivers.

New gene therapy to restore retinal cone function and day vision

Veterinary ophthalmology researchers from the University of Pennsylvania have used gene therapy to restore retinal cone function and day vision in two canine models of congenital achromatopsia, also called rod monochromacy or total color blindness.

Men have more red in their faces and women have more green

Michael J. Tarr, a Brown University scientist, and graduate student Adrian Nestor have discovered this color difference in an analysis of dozens of faces.

Penn researchers identify first sex chromosome gene involved in meiosis and male infertility

A team of scientists led by University of Pennsylvania veterinary researchers have identified a gene, TEX11, located on the X chromosome, which when disrupted in mice renders the males sterile and reduces female fecundity.

Colour blindness in cricket can be managed, study shows

Cricketers batting without a sight screen or fielding in the out-field are likely to be most disadvantaged by their colour blindness, a new study has found.

Researchers use gene therapy to restore sight in mice

University of Florida researchers used gene therapy to restore sight in mice with a form of hereditary blindness, a finding that has bearing on many of the most common blinding diseases.

Structural variation in the human genome

A major new effort to uncover the medium- and large-scale genetic differences between humans may soon reveal DNA sequences that contribute to a wide range of diseases, according to a paper by Howard Hughes Medical Institute investigator Evan Eichler and 17 colleagues published in the May 10, 2007, Nature.

Women perceive color better than men

Stereotypes about the superior color sense of women may well be rooted in genetics. Brian Verrelli, a researcher at the Biodesign Institute at ASU, is co-collaborator on a study suggesting that natural genetic selection has provided women with a frequent ability to better discriminate between colors than men.

Geographic variations in colour perception

It's long been known that color blindness is caused, usually in men, by changes in the red and green opsin genes, the genes that enable humans to perceive color.
