Researchers measure the basis of color vision

Dr. Wolf M. Harmening from University Eye Hospital Bonn, together with American colleagues, studied color vision by probing individual sensory cells - photoreceptors - in the human eye. The results confirm that the photoreceptor ...

Scientists deploy CRISPR to preserve photoreceptors in mice

Silencing a gene called Nrl in mice prevents the loss of cells from degenerative diseases of the retina, according to a new study. The findings could lead to novel therapies for preventing vision loss from human diseases ...

Midnight Blue—A new system for color vision

The swirling skies of Vincent Van Gogh's Starry Night illustrate a mystery that has eluded biologists for more than a century—why do we perceive the color blue in the dimly lit night sky? A newly discovered mechanism of ...

How does color blindness affect color preferences?

(Medical Xpress)—Dichromacy is a color vision defect in which one of the three types of cone photoreceptors is missing. The condition is hereditary and sex-linked, mostly affecting males. Although researchers have explored ...

Color vision tends to fade with age, study finds

(HealthDay)—Here's one more ability that seems to decline with age: color sense. A new study finds that many people lose their ability to clearly distinguish certain colors as they age, with losses typically starting around ...

Color vision problems become more common with age

Abnormal color vision increases significantly with aging—affecting one-half or more of people in the oldest age groups, reports a study in Optometry and Vision Science, official journal of the American Academy of Optometry.
