I've tried both, but my problem with the prisms is that my dv doesn't remain the same. If I'm having a good day, the prisms work fine. But, if I'm having a bad day, they don't. I have found that putting scotch tape on one lens works fine. I drive all the time and yes, my depth perception is off, but you can learn to adjust. I'm am now a much more careful driver than I ever was!

I think I made the decision to use then scotch tape when I spoke with my interinst. Turns out he has a glass eye he received at age 17 and has lived his entire adult life with single vision. Yes, he still has perception problems, but he has learned to adjust as do all other people with only 1 eye.

Good luck with your decision.
