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.
