This Snellen eye chart features 11 rows of optotypes (letters) decreasing in size from top to bottom, calibrated for visual acuity measurement at standardized distances (e.g., 20 feet). The green line marks the 20/25 row, and the red line highlights the 20/20 threshold-common benchmarks in clinical and self-assessment settings. Designed for high contrast and legibility, it supports both professional eye exams and preliminary vision screenings.

Used in optometry clinics, schools, driver’s license centers, and telehealth platforms for assessing visual acuity; matches user intent for vision testing, educational resources, or printable diagnostic tools.
