Human eyes are actually spheres ... 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 ...

The team noted high expression of RA synthesis genes early in human retinal organoid development that decreased over time, similar to what occurs in zebrafish. To test whether RA promoted M or L cones ...

So, at the outset, nocturnal eyes gather more light than human eyes do ... to two different kinds of light receptor cells—rods and cones. (Both are named after their relative shapes.) ...

Eye diseases often develop asymptomatically for many years. ICTER scientists have developed the f-ORG technique, which ...

Inside the human eye, the retina is made up of several types of cells, including the light-sensing photoreceptors that ...

Drag the slider to the left to see how an animal would see the same scene. Whereas human eyes contain three types of colour-detecting cells, called cones, dogs have just two. Their cone cells are ...

Researchers report they have used retinal cone photoreceptors derived from human stem cells to restore vision in mice with advanced retinal degeneration. They are now designing a clinical trial to ...

They are far more sensitive to light than cone cells, which is why you can sometimes see stars out of the corner of your eye at night, but when you look straight at them they seem to disappear. 5.
