retinal implants
Retinal implants are medical devices designed to restore vision in people with certain types of blindness, particularly those affecting the retina, which is the light-sensitive layer at the back of the eye. These implants work by converting light images into electrical signals that stimulate remaining healthy retinal cells, sending visual information to the brain. They can help individuals perceive shapes, movement, and some contrasts, but do not fully restore normal vision. Research and technology continue to advance, offering hope for improved devices and potentially better vision outcomes for patients in the future.

Retinal implants are medical devices designed to restore vision for people with certain types of blindness, particularly those with severe retinal diseases like retinitis pigmentosa. These implants typically consist of a small electronic device placed on or near the retina, which converts visual information into electrical signals. These signals are then transmitted to the remaining functional retinal cells, allowing them to send visual information to the brain. While retinal implants do not restore natural vision, they can help users perceive light and shapes, improving their ability to navigate their environment and enhancing their quality of life.

Retinal implants are devices designed to restore vision in people with certain types of retinal diseases, such as retinitis pigmentosa. These implants work by bypassing damaged photoreceptors in the retina. They typically consist of a small chip placed in or on the retina that captures light and converts it into electrical signals. These signals are then sent to the brain, which interprets them as visual information. While retinal implants won’t restore perfect vision, they can help users perceive light and shapes, improving their ability to navigate their surroundings and enhancing their quality of life.
