New bifocal contact lenses - is it normal at first for one eye to be blurrier than the other?

Multifocal contact lens fittings are usually more difficult than single vision lens fittings. Your eyes are suppose to work together to get you clear vision so I would wear them for at least 4 days before going back to your doctor. Make sure you put them in first thing in the morning. If the add powers are different in each eye then that could cause you some problems. Also make sure that one lens is not inside out. Some patients have such bad vision that they can't tell if it is or isn't in right by looking at it.
