Retina Implant Restores Vision With No External Hardware
Just after the FDA approved a special pair of glasses that help restore vision to the blind, a German company has built a system which requires no external hardware to function properly.
What's the Latest Development?
Hot on the heels of an FDA-approved device which helps blind patients distinguish color and shapes with the help of specialty glasses, a German company named Retina Implant has created a microchip that restores vision without any externally visible gear. "The implanted device consists of a three-millimeter-square chip with 1,500 pixels. Each pixel contains a photodiode, which picks up incoming light, and an electrode and an amplification circuit, which boosts the weak electrical activity given off by the diode." A thin cable that runs through the eye socket connects the implant to a small coil implanted under the skin behind the ear.
What's the Big Idea?
Thanks to advances in biotechnology, visual prostheses now occupy a large share of the cutting-edge medical device market. These devices are simultaneously available to the public. "More than 20 groups worldwide are working on some form of visual prosthesis, says Joseph Rizzo, a neuro-ophthalmologist with Massachusetts Eye and Ear Infirmary and Harvard Medical School, who is also developing an artificial retina." Thanks to Retina Implant, eight of the nine patients in the device's clinical trial could perceive light and five were able to detect everyday objects such as cutlery, doorknobs, and telephones.

These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
