An artificial retina designed to help some blind people regain their sight has already paid dividends for a few patients. Developed by the U.S. company Second Sight, the Argus II is an implant that can be surgically inserted into a patient's eye. A small camera attached to the patient's glasses captures images, and transmits them to a small wireless computer. The computer processes the images, ...

Share In September, we briefly mentioned a new device that could return sight, in limited fashion, to blind patients through the use of an electrode covered "lollipop." The inch-long device is placed on the tongue and is fed electrical signals from a small camera hidden in a pair of sun glasses. These small electrical impulses allow patients who have lost their sight to recognize simple ...

We've discussed eye implants that could eventually restore partial vision to people suffering from hereditary diseases like retinitis pigmentation, but for many others, a practical, medical solution for their near-to-total blindness remains painfully elusive. Stanford University researchers may be well on their way to solving that problem. One of the biggest obstacles that they've had to ...

Much of our Web perusal can be broken down into two distinct types: scanning and in-depth reading. Longer-form articles tend to be easier to read on a single, scrollable page, so the print/one-page option (if available) and some ninja-fast text-resizing can sometimes improve a piece's readability. Unfortunately, many sites no longer offer print-ready versions of articles. Readability, a tool ...

Far from the first circuit-laden contact lens we've laid eyes on (ahem), researchers at UC Davis have more than bragging rights in mind with their "smart" contacts. The devices are infused with a "pattern of conductive silver wires, which could be used to measure pressure inside the eye." The material, dubbed polydimethylsiloxane (PDMS), would boast antimicrobial properties and could enable ...
