When I was a 20 something, I considered getting contact lenses. My ophthalmologist said he would prescribe for just my right eye as I was virtually blind in my left. This was due to eye surgery when I was 8 to correct an in-turned eye. The surgeon over compensated and my eyes do not focus together...I don't have binocular vision. What I see with my right eye, is all I see. I tend to squint/wink...otherwise I'll have a bit of double vision. I also have bad astigmatism.
I did try learning to drive, but plowed into a tree with my brother's car...and gave up on the idea.
