I'm the other way around, Smitty.
When I was young, it was discovered that my right eye had turned-in slightly and was very weak. I was made to wear a patch over my left eye for two years, to try to strengthen the bad eye, but it didn't work. You can imagine the fun other kids had in teasing me!
My left eye is now fading, so I've had to start wearing glasses, but only really for reading.
Due to the turn, I don't have correct 3D vision and suffer from the depth-perception problem you talked about, but, because I've had it for soooo long, my brain's figured out how to deal with it. I have no problem playing ball sports, except for one thing. Every time I go for a smash in tennis, I always swing before the ball gets to the racquet! VERY embarrassing.
I recently looked into getting prism lenses, that would correct the vision my right eye is seeing. When the Optometrist finally got the correct alignment, I was like, "Wooooaaaaa, holy sh*t, ths is too freaky!" In the end, we decided that, since my brain had learned to handle to fault, we'd just leave it alone. Besides, I would need a lense that was quite thick on one side, but thin on the other.
Sorry for my ramblings. Back to the topic...
I don't think a prescription visor would work. What about some cheapie glasses? Over here, you can buy them at petrol stations, chemists, etc. They just come in basic frames and 'scripts. I've heard of people buying them just for the frames ('cause they're so cheap), then getting their proper lenses made for them.
