The retina is home to two different kinds of light receptor cells—rods and cones. (Both are named after their relative shapes.) Cones work in bright light and register detail, while rods work in ...

A team of engineers, computer scientists and ophthalmologists at the University of California, Berkeley, working with a pair of colleagues at the University of Washington, has developed a technique ...

Inside the retina, there are millions of special sense receptors called rods and cones. The rods see the shapes of things, picking out black, white and shades of grey… and the cones see colours ...

but it has not been known why cone photoreceptors die. After rods die, the level of oxygen in the retina goes up, and this work shows that it is the high oxygen that gradually kills the cones.

The reason lies within the eye. In the eye are light receptors called cones and rods. Cones help us distinguish different colors, while rods help us see in dim light. The number of cones and rods ...
