Check out the Drugs section on PC here. It says one of the side effects of Tegretol is blurred vision. I'd definitely get it checked out. That can't be good. Even of your P-doc is out of town, can you go to another for this issue? It's not good to change your dose without talking to a psychiatric professional. They may lessen your dose anyway, but they may give you something else in case you're not getting the effects you need with a lower dose. Hope this helps.
