Anton–Babinski syndrome

Anton-Babinski syndrome is when a person has a problem with their eyes that makes them unable to see, but they don’t know it. It’s kind of like wearing a pair of glasses that change the way you see things but not realizing that you are wearing them.

So imagine that you are looking at a tree, but the tree appears to be moving around, changing colors or even disappearing. You might think that there is something wrong with the tree, but in reality, it’s your eyes that are not working properly.

Anton-Babinski syndrome mainly affects people who have had a stroke or brain damage. It happens when the part of the brain that controls vision is damaged, but other parts of the brain still work. As a result, the brain fills in the missing information with made-up images, which makes it seem like everything is normal.

So even though a person with Anton-Babinski syndrome may not be able to see, they’ll still be able to describe what’s “happening” around them like they normally would. It’s a very rare condition, but it’s important that people know about it, so they can get the right help and support.
