Variable

Detailed Answer:
Hello,
Welcome and thanks for your query.
The pupillary dilatation by atropine can last from one day to one week.
There used to be a product called Rev Eyes which could reverse the pupillary dilatation earlier, but it is not available now.
Pilocarpine drops which is normally used to treat glaucoma produces a pupillary constriction opposing the effect of atropine.
You can lessen the discomfort of dilated pupils by wearing dark glasses.
