Is it common to have blurred vision with pupil dilation?

Yes.: It is common, expected and practically universal. Your pupil is dilated by the eye doctor in order to be able to get a better and more complete view of the back internal structures of your eye (retina, macula, optic nerve). The drug induced dilation temporarily paralyzes the muscles in the iris & ciliary body that one uses to properly focus resulting in temporary blurred vision mostly at near.
