Snellen Eye Chart - Standard Visual Acuity Test for Eye Exams #51250 (License: Personal Use)

This is a standard Snellen eye chart, designed to assess visual acuity by having patients read letters from a fixed distance (typically 20 feet or 6 meters). The chart includes eight rows of optotypes-standardized letters-with the largest at the top (the “E”) and decreasing in size downward; green and red lines highlight specific rows for color vision or contrast sensitivity checks. It remains a foundational tool in ophthalmology and optometry for diagnosing refractive errors like myopia or hyperopia.

Used in clinical eye exams, vision screenings, and optometric offices to evaluate distance visual acuity. Matches user intent for educational content on eye health, vision testing procedures, or medical illustration needs.
