How is farsightedness diagnosed?

A routine eye exam by an ophthalmologist or optometrist can show whether you are farsighted. 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.
What is nearsightedness?
Nearsightedness or myopia affects a significant number of people. But this eye disorder is easily corrected
with eyeglasses , contact lenses , or surgery.
People with myopia or nearsightedness have difficulty seeing distant objects, but can clearly see objects that are
near. For example, a person who is nearsighted may not be able to make out highway signs until they are just a
few feet away.
