How is nearsightedness diagnosed?
A routine eye exam can show whether you are nearsighted. The eye exam includes questions about your eyesight and a physical exam of your eyes. Ophthalmoscopy, tonometry, a slit lamp exam, and other vision tests are also part of a routine eye exam. Eye exams should be done for new babies and at all well-child visits.1 Nearsightedness is usually first discovered in children of grade-school age.
