Equipment to help blind people see exactly 89%

Researchers at Second Sight have developed a new device called Argus, which allows blind patients to see the text by stimulating the light-sensitive part of the eye. Braille types are transferred directly into the patient's retina, allowing them to read four-letter words quickly and accurately.

The results of the study are published in the journal Frontiers in Neuroprosthetics.

An image, such as a four-character letter from the camera, is converted into electrical impulses via a mobile processor. The microchip in the eye receives these impulses through a receiver, allowing it to direct the image onto the nerve cells of the eye using a 60-electrode network.

This device has been successfully implanted on more than 50 patients, allowing many of them to see things, movements, even color. Thomas Lauritzen, a senior researcher at Second Sight, said in a clinical trial, "We directly stimulate the retina instead of using a camera - often referred to as an input device for implantation. transplant Instead of sensing braille with his fingertips, patients can see the letters lit up and then read individual letters in less than one second with an accuracy of up to 89%.

Argus 2 is primarily aimed at patients with retinitis pigmentosa.
