Rick Inman:When I dive, I switch to bi-focal contacts. That works for me.
Yeah, I just started this last year with these throwaway contacts (wear them once and toss them), with the left eye adjusted for near vision - more or less - and the right for mid to long range vision. It actually works pretty well for most things, but the left eye correction is not where it needs to be for reading stuff right in front of me, because it's a compromise between near and mid-distance. I've been getting by with this arrangement, but I think I'm going back to reconsider bi-focal contacts (an option I passed on when I decided to try this).
