Duration of Dilating Drops

Pupil dilation tends to last longer in people with lighter colored eyes and occasionally a child’s eyes may remain dilated longer than 24 hours. The duration of action is specific to the drug used. Also, if two different classes of drugs were employed, the results will last longer. Your ophthalmologist can tell you most accurately what to expect based on the drug used. Responses to any drug may produce different effects in individuals, but call the office if you or your child’s eyes are still dilated after 24 hours.
