The Illiterate Eye Chart (Tumbling E) – 20FT is specifically designed for patients who are unable to read or recognize letters. Instead of letters or numbers, the chart uses the letter “E” in different orientations (up, down, left, right) to assess visual acuity.
This chart is highly effective in pediatric eye exams, patients with literacy barriers, or those with language differences. It provides a reliable, standardized method of testing vision at a distance of 20 feet.
