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.
Dilating eye drops used for examination of the eye usuallylast from 4 to 24 hours, depending upon the strength of the drop and upon the individual patient. Pupil dilation tends to last longer in people with lighter colored eyes (irides), and occasionally a childâs eyes may stay dilated for longer than 24 hours. Children require stronger and longer lasting drops than do adults to accurately measure refractive error. Weaker drops are used for premature babies and neonates.
