Summary:
- Researchers have developed a tiny implant, about the size of a grain of sand, that can restore some vision in people who are clinically blind.
- The device, called the Alpha AMS, is surgically implanted behind the retina and uses light-sensitive pixels to stimulate the retina's remaining healthy cells, allowing the brain to perceive basic shapes and patterns.
- Initial clinical trials have shown promising results, with some patients regaining the ability to navigate their environment, identify objects, and even read large-print text, offering hope for those with certain types of blindness.
