Visual Acuity Test

This designation represents average or typical visual acuity. A person with 20/20 vision can read specific letter sizes at a distance of 20 feet that an average person would also be expected to read.

Visual acuity can generally be improved or maintained by wearing corrective or contact lenses with a suitable prescription. Regular eye exams, a healthy lifestyle and diet, and, in some cases, surgery can also improve visual acuity.

Visual acuity tests are fundamental in healthcare. They help detect eye conditions early, provide a measurable benchmark for monitoring vision changes, guide the prescription of corrective lenses, and alert healthcare practitioners to potential systemic health issues.
