A visual acuity examination is a fundamental assessment in ophthalmology used to determine the sharpness or clarity of one's vision. This test commonly involves reading letters on a chart at various distances. The standard visual acuity chart, known as the Snellen chart, presents progressively smaller letters to patients to read. The results of this examination are expressed as a fraction, such as|e.g., 20/20, where the top number indicates the distance at which the patient can read the letters and the bottom number refers to the distance at which a person with normal vision could read the same letters.
Comprehensive Ophthalmologic Evaluation
A comprehensive ophthalmologic evaluation is a fundamental part of maintaining overall health. It involves a meticulous examination of the eyes by an ophthalmologist, a specialist trained in the diagnosis and treatment of eye diseases and vision disorders. This evaluation encompasses a variety of tests to assess various aspects of eye health, including visual acuity, color vision, binocular vision, refraction, intraocular pressure, and the overall health of the back of the eye.
- The results obtained from a comprehensive ophthalmologic evaluation can help detect early signs of eye disease or vision problems that may otherwise go unnoticed.
