How long does it take for pupil dilation to end?
A doctor has provided 1 answer
4 hours: Usually, around 4 hours, however in eyes that are lighter in color, blue, two-toned, or green the effect of the drops can last beyond 4 hours. In small children, although rare, the effect can last up to a week or more.
