Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed ...

Then, they fired precise laser pulses—100,000 times per second—at specific green-sensitive cones, while tracking minuscule eye movements 960 times per second to keep the aim steady.

Human eyes have three types of cone cells: red-sensing cone cells, green-sensing cone cells, and blue-sensing cone cells. 60% of your cones are red-sensing, ... The back of the eye.

Cones outnumber rods only in the center of the retina, which is the area of greatest density. It is also the area most heavily used by daytime, direct vision. But rods do fire during the day, ...

Cone-rod dystrophy is a group of IRDs that damage cones and rods. Vision loss gets worse over time. Between 1 in 30,000 and 1 in 40,000 people have cone-rod dystrophy.

Scientists at the Jules Stein Eye Institute at the David Geffen School of Medicine at UCLA have discovered that certain ...

Cones are a part of the eye that enables people to see colors. The extent and type of deficiency depend on which cone cells are missing or damaged in a person’s eye.
