Smart Glasses to Help People With Poor Vision to Navigate, Recognize People and Things

Oxford University is touting the work of its researchers who are building a special set of electronic glasses that may help people with all sorts of vision conditions. Cameras in the frame would analyze the scene ahead and active glass would display important things either in a different part of the frame of view or interpret it with colors, brightness, and basic representations. The idea is being profiled at the Royal Society Summer Science Exhibition where visitors get to see how the system would function.

Drug Delivery Device Uses Magnets to Treat Diabetic Retinopathy

Diabetic retinopathy is a complication of diabetes mellitus that can eventually lead to blindness. Current treatments are not the terribly effective or reliable. For example, drugs in the form of eye drops often have a lower than desirable rate of diffusion into the eye, as well as potential systemic side effects. And, for obvious reasons, most patients aren’t too fond of the more direct needle in the eye approach.

At the University of British Columbia, researchers have developed a novel device that will make drug treatment for diabetic retinopathy safer and more effective. The device, no larger than the head of a pin, consists of a sealed reservoir made of flexible polydimethylsiloxane that is implanted behind the eye. Part of the reservoir’s flexible membrane is magnetic; an electric field applied to the device causes the magnetic membrane to deform and release a controlled amount of drug out of a small hole, much in the same way water is released from a plastic bottle when it’s squeezed.
