Eye specialists called ophthalmologists and optometrists may use special eye drops called mydriatics to dilate the pupils during eye exams.

Around 15 to 30 minutes after this treatment, the pupils will dilate, making it possible for the specialist to get a good look at both the retina and the optic nerve. Being able to see these components of the eye can provide key indicators of eye health and signs of serious problems.

Eye exams may be conducted to look for problems, such as glaucoma , macular degeneration , and other eyesight-threatening conditions. The effects of the eye drops usually wear off in 4 to 6 hours.

This can lead to blurry vision, as well as, in some cases, a general feeling of constriction around the forehead and eyes. Some individuals may also experience headaches, dizziness, eye irritation, and have trouble sleeping along with mydriasis.
