In retrospect (there's a good one), optician may not be that useful after all. I think the reason I originally listed it was because I believe that knowing what to call something can greatly increase your (apparent) intelligence...that is, if you can say optician as opposed to eye doctor or "that doctor that gives you glasses or contacts". Then again, how often does that really come up? Thanks for pointing that out.

oh, and to tsuwn...they may not be useful, but those are great words!
