Photoreceptors cells responsible for colour vision. By sequencing one cell at a time, the researchers identified a gene (Rbp4) present in a small number of cells (in green). In purple, photoreceptors in which the Rbp4 gene is not activated.

Scientists unveiled the first steps in the construction of vision

By decoding the genetic mechanisms that control the neurons of the visual system, researchers at UNIGE are unveiling the first steps in the construction of vision, paving the way for regenerative eye medicine.
The findings indicated significant changes in the smokers’ red-green and blue-yellow color vision and that heavy smokers had a reduced ability to discriminate contrasts and colors.

Heavy smoking can damage your vision, study

Everyone is aware that smoking is indeed bad for the health. Still, some people do it anyway. Smoking has been proven a cause of numerous...
An artist’s rendering incorporates the images of the Müller glia-derived rod photoreceptors. These photoreceptors were structurally no different from real photoreceptors and they became integrated within the circuitry of the visual pathway, from the retina to the brain. Courtesy of Bo Chen, Ph.D.

New method that allows a blind to see again

Scientists financed by the National Eye Institute (NEI) have switched congenital visual blindness in mice by changing supportive cells in the retina called Müller...
Dr. Ajith Karunarathne examined toxic oxygen generation by retinal during blue light exposure.

How blue light speeds blindness

We are being exposed to blue light continuously, and the eye’s cornea and lens cannot block or reflect it. It's a dependable fact that blue...

Scientists Have Created an Artificial Retinal Implant That Could Restore Vision to Millions

The retina a light-sensitive layer located backside of the eye covers about 65 percent of its interior surface. It consists of millions of light-sensitive...
