    Only the doctor tell you to do this, then it is necessary.otherwise there is no need to dilate you pupils, because is gonna feel uncomfortable for a while. If the doctor tell you to dilate your pupils is to eliminate the error of pseudomyopia,becausethe result after the mydriatic is more accurate.
