A few years ago, scientists discovered another type of light-sensitive cell
in the eye.
Fluid passes in a narrow film through a light source, which has a light-sensitive cell

Rather than just four openings, such a chip would have thousands, each filling in for a lost light-sensitive cell
that could then relay visual signals to the brain.
Dry AMD, caused by the breakdown of light-sensitive cells
in the macula over several years, progresses more slowly and affects your ability to see fine detail.
com/5926497/what-happens-when-you-stare-at-the-sun) sunburn on your corneas , the protective outer layer of the eye, and your retinas, the group of light-sensitive cells
that are like the film in a camera.
uk), said: "The light-sensitive cells
in our eyes help feel alert set our sleep pattern - getting natural light onto those receptors for at least 10 minutes tells the body the day has started.
AMD is a progressive disease that causes the death of the retinal photoreceptors, the light-sensitive cells
at the back of the eye.
Giving up smoking is very important for maintaining good eye health as smokers are more likely to develop cataracts (cloudy patches that develop in the lens of your eye) and age-related macular degeneration (blurry vision caused by light-sensitive cells
The dry form is characterized by the slow buildup of residue from the breakdown of the light-sensitive cells
in the macula, the part of the retina responsible for your sharpest central vision.
Leeds-based Laura was diagnosed with Stargardt's disease, a rare inherited condition, which causes the light-sensitive cells
in the retina to deteriorate, resulting in central vision loss or, in some cases, total blindness.
An important type of outer retinal degeneration is Retinitis Pigmentosa, which is a rare, hereditary disease that causes a progressive degeneration of the light-sensitive cells
of the retina, leading to significant visual impairment and ultimately can lead to blindness.
