Pixium Vision Implants Restore Sight in Rats with Retinal Degeneration, Humans Next (VIDEO)

Prima Vision, a company based in Paris, France, is reporting that its PRIMA wireless subretinal implants for people who lost their vision has show a great deal of promise in a pre-clinical trial. The technology is designed specifically for those whose natural photoreceptors no longer function, yet who retain retinal neurons that can be electrically activated. A bunch of the implants are injected into the back of the eye, each around 70-μm in width that represents a single pixel. The implants are basically tiny photovoltaic solar panels that emit electricity in response to light hitting their surface.

ABOUT once a month I run across a person who radiates an inner light. These people can be in any walk of life. They seem deeply good. They listen well. They make you feel funny and valued. You often catch them looking after other people and as they do so their laugh is musical and their manner is infused with gratitude. They are not thinking about what wonderful work they are doing. They are not thinking about themselves at all.

When I meet such a person it brightens my whole day. But I confess I often have a sadder thought: It occurs to me that I’ve achieved a decent level of career success, but I have not achieved that. I have not achieved that generosity of spirit, or that depth of character.

Will Your Child Become Nearsighted? One Simple Way To Find Out

This is for everyone whose parents said, "Sitting too close to the TV is going to ruin your eyes." In other words, pretty much all of us.

Sitting too close to the TV doesn't predict nearsightedness, according to a study that tracked the vision of thousands of children over 20 years. Nor does doing a lot of close work.

Instead, as early as age 6 a child's refractive error — the measurements used for an eyeglass prescription — best predicts the risk.
