A visual acuity examination is a fundamental assessment in ophthalmology conducted to determine the sharpness or clarity of one's vision. This test typically 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 in 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.
A Thorough Eye Examination
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 sight disorders. This evaluation encompasses a range of tests to assess various aspects of eye health, including visual acuity, color vision, depth perception, refraction, intraocular pressure, and the overall health of the retina.
- The information obtained from a comprehensive ophthalmologic evaluation can help detect latent signs of eye disease or vision problems that may otherwise go unnoticed.
- Regular examinations are strongly recommended for everyone, regardless of age or current eye conditions.
