Wearing glasses? Help!

[BigRedBeta]

So I've always, always, always worn contacts. Been wearing them since the 8th grade (so about 10 or 11 years ago) and haven't even owned a pair of glasses during that time. The last pair of glasses I had was in 7th grade and I only wore them for distance at that time, and my vision has changed a lot since then. Because of the pain of wearing contacts for nights I'm on call at the hospital, I asked my optometrist to write me a script for glasses along with my contacts. In addition to doing this, she switched my contacts to those that you can wear for 30 days straight as another solution for overnights call and the like. The new contacts have been phenomenal.

My glasses came in the mail today, and I was a little eager to try them out tonight while I'm at home, just to kind of get used to them. They look good, but I'm noticing that my vision out of my right eye (which has astigmatism) items appear smaller than they do in my left eye (which doesn't have the astigmatism, just nearsighted). This is giving the world a slight tilt and makes looking at things out of my peripheral vision very odd. Is this something I should be worried about? Will I need to get new ones? Or will I adjust to this over time...even if I'm wearing the glasses pretty infrequently? It's Friday, so I can't call the office at all to talk to my OD, so I figured I'd turn to GC for some guidance...

Any help would be appreciated.
