Argus: Let the blind see the bright wearable device

By implanting an electrode grid in the human eye and then pairing a special "sunglass", Argus allows some blind people to see the shape and color of the object again.

After more than 20 years of research, the Argus equipment of Second Sight of the United States has finally passed the FDA (Food and Drug Administration) certification. It allows some blind people to see the shape and color of the object by implanting an electrode grid in the human eye and then matching a special "sunglass".

Argus: Let the blind see the bright wearable device

Seeing the light again

Dean Lloyd began to lose sight in his twenties, and it was in the early 1960s when he was studying medicine. The doctor diagnosed him with Usher Syndrome, saying that he would be blind and deaf in a few months, and dementia would follow.

"My situation is not good." Lloyd smiled and recalled the past.

As a result, Lloyd got another disease. He has congenital retinitis pigmentosa, a disease that gradually engulfs his retina, especially photoreceptors. Once these cells die, the eyes cannot transmit and decode the outside light, leading to blindness.

Lloyd's illness deteriorated slowly. Although he had poor eyesight at night, he did not have any other visual impairment at first. He turned to Stanford to do biochemistry research and then worked as a software engineer. When his vision deteriorated to the point of looking at the code on the computer screen - he said that the visually impaired programmer had no assistants in the year - he decided to try the law school. With the help of two readers, Lloyd passed the exam and began his legal career in 1982. At that time, his vision was very limited.

In 1989, he was finally completely blind.

"In 17 years, my world has been dark," he said. "Until 2007, I had Argus."

Argus is the name of a hundred-eyed giant in Greek mythology. He can see things in all directions. This is actually a wearable computer that helps blind people see boundaries at very low resolutions. We reported this device for the first time about eight years ago and it was still testing. Now, it is finally certified by the US FDA and can be used in patients with similar conditions to Lloyd in the United States. The device will soon be available in several medical centers, including the University of California, San Francisco.

Argus is not really a "blind eye" - patients can't see things like normal people. However, they can see the black and white borders and contrast points , and through training, they can use these artificial data for visual guidance. This approach provides enough visual information to help the patient achieve a degree of independence, safely crossing the street, or walking around in a strange room.

"You have to relearn and see things, but people who use this equipment have seen things before." Lloyd said, "When you have experienced these misfortunes, you still have the various things you have seen before. The image of the thing. So, you can create the image yourself and match it with the memory. Many people don't think about it when thinking about this device."
