Spatial vision from 2D picture is not about your eyes, but about your brain ; on a side note, if you have thick glasses it's not a problem in a general way as long as they give you a 10/10 vision.
And as you said "how did you think i could win tournaments that way?", I guess you implied you were at disadvantage playing without preview, so it means you see the ball less well without them, so that reinforces my point that the previews are needed to appreciate the ball trajectories as easily as on a real court...
