The duration of pupil dilation depends on the type and concentration of the drug used. Generally, dilation lasts three to six hours. Sometimes, the dilation can extend up to 24 hours if a more concentrated drug is used. Atropine is a common eye drop used to dilate pupils during eye examination. Eye color can also determine the duration of pupil dilation.
How long does dilation take and how long will the effects last? It normally takes 20 â 30 minutes for the eyes to dilate. It then just takes 5 â 10 minutes for the doctors to examine them. The pupils will remain larger than normal for 4 â 6 hours causing increased light sensitivity but vision is back to normal usually within the hour.
