Depending on the exact vision problem, a plane that moves fast and changes its distance from you quickly might be tough. In that case a slow plane that can stay in a small area, even a small and slow plane, might work out well. It takes a while to learn to keep any plane in a very small area, though.

My eyesight, with glasses, is OK but I still like to fly sort of up close so that I can see what exactly the plane is doing.
