I was born blind in one eye and although I am no doctor I believe me eye uses size of shapes and shadows to determine distance. This lets me drive a car and be fine. However if you ever watch me try and catch a pop fly there is nothing in front or behind the ball for my brain to compare it to. I will run up and back many times try to adjust and it still feels like a guess. Sometimes I’m right most of the time I’m correcting at the last second when the ball is large enough to better judged the distance. That is in adult softball. Because there is no way in hell I could ever hit a baseball pitch. My 2 cents
