Snellen Eye Chart - Visual Acuity Test for Optometry and Vision Screening #3279829 (License: Personal Use)

This is a standard Snellen eye chart featuring bold, high-contrast black letters (optotypes) arranged in decreasing size from top to bottom, calibrated for testing visual acuity at distances ranging from 20 feet (6 meters) to 200 feet (61 meters). Each row corresponds to a specific visual acuity measurement (e.g., 20/20, 20/40), with the right-side annotations indicating test distance in feet and meters. The chart follows the original design principles established by Herman Snellen in 1862.

Commonly used in optometry clinics, school vision screenings, and telehealth assessments; patients read letters aloud while standing or sitting at a fixed distance to determine their visual acuity. Matches user intent for medical education, printable vision tests, or clinical reference materials.
