In the retina, the cells responsible for the visual experience are rods and cones. These cells are called photoreceptors and they absorb and convert light into electric signals.

These recordings revealed that the remaining cones in a retina where the rods have mostly degenerated were still functional. Although the anatomic specializations that are responsible for ...

A cat's visual acuity is anywhere from 20/100 to 20/200, which means a cat has to be at 20 feet to see what an average human can see at 100 or 200 feet. This is why the bottom picture is so blurry.

Cones & Rods. The retina (the screen upon which the lens of the eye casts the image) has two kinds of visual cells: cones, each with its direct line to the brain; rods connected in multiple to the ...

No cases of retinal vasculitis were reported in any of the groups, he said. “What’s most meaningful about this study is ANX007 protection from vision loss and its safety,” Khurana said.

There’s a relay race in your eye that allows you to see. It begins when light hits the rod and cone cells in your retina, triggering a cascade of electrical signals. These pass through other ...

A cat's visual acuity is anywhere from 20/100 to 20/200, which means a cat has to be at 20 feet to see what an average human can see at 100 or 200 feet. This is why the bottom picture is so blurry.

To monitor visual performance in early age-related maculopathy (ARM). We measured monocular visual function—high-contrast visual acuity (HC-VA), central visual fields (mean sensitivity, MS ...

New visual simulations give us a glimpse of what it might look like to see the world through bionic eyes. Since the FDA’s approval of the world’s first bionic eye system, the Argus II, more ...
