An eye patch eliminates double vision but it impairs your depth perception. You can drive but definitely you have to be a aware of that.

My vision is not bad enough to require glasses for driving. The optometrist did not think I needed glasses because the prescription was so minimal. I insisted.

I did the same thing Jana did but I used a black marker to paint the tape but maybe I did not have to paint it. I don't know now because my DV is gone but the little bit of improvement in the one eye eliminated the blurry vision in that one eye.

I still wear the glasses without the covering when I am driving because I still have a little bit of blurry vision and using them makes driving much easier and eliminates headaches.
