Hope is dawning for all the blind people in the world. Scientists at the University of California, Los Angeles (UCLA) are almost on a breakthrough in bringing back precious eyesight to people by means of a bionic eye. What these scientists developed isn’t an eye replacement; rather a visual stimulator chip is implanted at the back of the brain, which sends signals directly to the brain. This new system bypasses the optic nerve to stimulate the visual cortex of the brain.
This bionic eye was tested on a 30-year-old woman who has been totally blind for seven years. When the chip was implanted on her brain, she saw lines and spots as well as coloured flashes when signals were sent to her brain from a computer. During the six weeks of testing, the subject saw the exact signals that the scientists sent via computer. And so far, the test subject hasn’t suffered any adverse effect from the procedure done to her brain.
However, what the Scientists have achieved thus far is not yet complete. The next step for this revolutionary bionic eye is to have the visual stimulator chip connected to a camera placed on the bridge of a pair of glasses that will be worn by the subject that is if it gets approved by the US Food and Drug Administration. Hopefully it does get approved for this new bionic eye promises to restore eyesight to those who have been seeing nothing but darkness for so long.
