I pick this video because it’s based on a young woman who has an eye disease that affects the retina. This video talk about what she can and can’t see, and due to this disease over time she will become blind. It talks about how the eye works and shows what goes on as light enters the eyes. I learned that people who suffer from this disease loses their rod cells over time leaving them with many blind spots. With this entire new technology scientist are now testing a silicon chip containing 5000 light sensitive cell, in hope that one day this can help those who are visually impaired. This video was awesome.
