Your ophthalmologist uses eyedrops to dilate, or enlarge, the pupil of the eye. This allows examination of the inside of your eye.
Because driving may be difficult immediately after a dilated eye examination, ask your ophthalmologist if you need to make arrangements for a ride home afterward.
Anesthetics are painkillers that numb the eyes within a few seconds. These drops should be used only in the doctor’s office and never at home. Repeated use at home can harm the surface of the eye, which could lead to an infection or serious scarring of the cornea.
