...especially when you get to THAT AGE (and some of you here will know what I mean, heh heh).

Peter's advice is good. At the very least, get used to wearing your contacts for reasonable lengths of time. The biggest problem I have with mine is them drying out, which REALLY gets uncomfortable (always have your wetting solution with you!).

Once you get used to them, it will be like you don't even know you're wearing them...

No, shooting with them should be no problem. Your eyeball doesn't touch any camera surface normally (at least god I hope not), so the contacts won't get in the way of anything either.

Like AV Steve, I usually wear contacts when I shoot. My problem (and this is where the age thing comes in, grrrr!) is that I'm nearsighted, but now have trouble seeing CLOSE UP too, so for me, there is no perfect way of working.

With my contacts in, I see fine to focus, but really have trouble reading my camera settings, especially tiny numbers in low light. This is actually much less of a problem with DSLRs, because I can read the LCD screen fine, but film cameras with their small dials are tough.

All I know is, the one thing I CAN'T do is shoot while I'm wearing my glasses...
