Bionic Eye Implantation on Retina can help the visually challenged see Braille

The creators of the Argus II retina prosthetic has formulated a way that can help the visually challenged friends to visualize the Braille letters instead of alphabets. According to the reports from technologyreview, the test performed with a person wearing Argus II could help blind people with the implant read signs and short sections of text. The Argus II eye prosthetic built for the people with retinitis pigmentosa – refers to a disease causing retinal degeneration.

The person with retinitis performs an implant on the eye, then the Argus II eye captures images through a camera positioned on the wearer’s face, which is connected to an electrode array. The images captured by the camera will be converted to electrical signals and transmitted to the electrode array, which in-turn stimulates nerves in the sections of the retina.

The test was performed with a person who had a retinitis pigmentosa, was successfully able to recognize 89% of letters – where the patient was able to recognize 80 percent of two letter words, 60 percent of three letter words and 70 percent of four letter words.

The research also says that the person wearing the Bionic eye can visualize bit slower than deciphering the letters via touch.
