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 ...

KUMAMOTO, Japan, Dec. 24 (UPI) --Rods and cones, the two main photoreceptor cells, are vital to human sight -- converting visible electromagnetic radiation into information our brains can use. And it ...

Scientists have discovered a fossilized fish so well preserved that the rods and cones in its 300-million-year-old eyeballs are still visible under a scanning electron microscope. It is the first time ...

Light-sensitive cells in the retina come in two main types: rods and cones. Rods are used for vision at low light and cones for color and bright light. A study in the September issue of the Journal of ...

Scientists have discovered a fossilized fish with its well-preserved eyeball containing rods and cones that are visible under a microscope. The discovery of the 300 million-year-old fish eye helped ...

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 ...

We investigated the cone- and rod-mediated mfERG in 17 eyes of 17 subjects with early ARM and 16 eyes of 16 age-matched control subjects with normal fundi. All subjects had a visual acuity of 6/12 or ...

Nocturnal animals tend to have proportionally bigger eyes than humans do. They also tend to have pupils that open more widely in low light. So, at the outset, nocturnal eyes gather more light than ...

Scientists in the U.S. have found a third kind of light-sensitive cell in the eye, which they say sets the body's internal clock. The newly discovered cells are shaped like twisted tree branches and ...
