Your Brain Can Choose To Go Blind

To avoid double vision, your brain can subconsciously switch off input from one of your eyes. This internal filter effectively creates a blind spot, allowing the brain to ignore conflicting information from a misaligned eye.

When your eyes fail to work as a perfectly coordinated team, you might see two of everything. To fix this, the brain simply stops processing visual data from the problematic eye entirely. While this prevents confusion, it can eventually lead to permanent vision loss if left untreated. It is a brilliant but risky survival mechanism that shows how much control your brain has over what you actually see.
