Both diseases also affect internal eye cells known as retinal pigment epithelium (RPE) cells.
The focus was on their exercise habits and eye health rather than being a scientific study of eye cells.
StemCell Ventures is working with the University College London's Institute of Ophthalmology to devise a patch containing adult-eye stem cells that could be implanted in the eye in hopes of restoring vision.
The modified liposomes were then added to the membranes of eye cancer cells - and sure enough the cells were found to respond to light.
The retina is the back part of your eye with the cells that respond to light.

The U.S. military has had its eye on miniature fuel cells for some time and has financed research at Lawrence Livermore National Laboratory and elsewhere.
But when the cells inside the eye are damaged, there is nothing we can do.
This causes the cells in the eye that receive and transmit light information to die over time.

At sunset, the sun appears red (the blue light has been scattered out of that image, too), so the cells of the eye that detect red are overloaded and incapable of registering weaker red signals.
Adult stem cells would be isolated in the lab over the next few hours, and then the patient would come back in the afternoon and get an injection of his own purified stem cells into the eye.
"The goal is to intervene with these progenitor cells, stabilize the eye and prevent things from getting worse, " said Friedlander.
Embryonic stem cells have also caught the eye of drug companies, which aim to use them to test potential drugs for effectiveness and toxicity.
It involved transplanting stem cells grown in a laboratory into the eye, followed by another cornea transplant.
The UCLA team describes a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent to the human eye.

The circumstantial evidence is intriguing: as well as being more abundant in tumours than in ordinary cells, vaults, to Dr Scheper's eye, seem to congregate around the vesicles.
The vast majority of colorblind people have trouble seeing red or green, due to a genetic defect in the color-sensing cells, called cones, at the back of the eye.
This travels into the brain along an optic nerve (there is one for each eye) to arrive at one of two small clusters of nerve cells called the lateral geniculate bodies.
When a beam of light is focused by the cornea and the lens, at the front of the eye, on to the retina, at the back, it stimulates photosensitive cells known as rods and cones.
Magnetic, nonradioactive nanoparticles (a tiny fraction of the thickness of a human hair and invisible to the human eye) are injected into the subject, where they bind only to known breast cancer cells within the body.
