Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection for ...

This is a confocal microscope image of rod and cone photoreceptors in a human retina. Fluorescent probes have been used to identify rod photoreceptors (green) and cone photoreceptors and horizontal ...

The human eye is incapable of distinguishing individual wavelengths but is sensitive towards different parts of the spectrum covering multiple wavelengths. The basis of the photometric principle is ...

A gene therapy that significantly improves vision in a form of Leber congenital amaurosis (LCA) does not slow global degeneration of photoreceptors, according to a report published online January 22 ...

The science of measuring color and color appearance is vital: The perception of color is a subjective process where the brain responds to stimuli produced when incoming light reacts with the several ...

Scientists have long believed that the eye uses the retina’s rod cells for vision at night and cone cells to see during the day. New research at The Ohio State University Medical Center, however, ...

Share on Pinterest New research involving cones and rods in the retina could lead to new treatments for vision loss. Gregory Adams/Getty Images Cone photoreceptors in retinal degeneration have been ...

In addition to allowing us to see, the mammalian eye also detects light for a number of “non-visual” phenomena. A prime example of this is the timing of the sleep/wake cycle, which is synchronized by ...

Using an experimental technique called "Oz," researchers stimulated the human retina such that people saw a brand-new color. When you purchase through links on our site, we may earn an affiliate ...

Sight begins when light bounces off surfaces and enters our eyes. The muscles of our pupils control how much light passes through, and the clear cornea and lens bend the light and focus it onto the ...
