Effects of Object Recognition on Vision Testing
A Study of the Effects of Object Recognition on Vision Testing Results
Michael Klein, 13, Atlantic Beach, N.Y.
Discovery Consumer Products "Telescope" Award, Discovery Channel Young Scientist Challenge, 2003
Project background: While waiting to get his eyes checked, Michael overheard the ophthalmologist giving a vision test to a Russian-speaking patient. He wondered if the difficulty the man had reading the eye chart had something to do with his unfamiliarity with the English language. He hypothesized that the accuracy of the vision testing results depended on previous familiarity with the testing objects being used.
Tactics and results: With the assistance of his ophthalmologist, Michael tested 31 patients using four different Snellen acuity eye charts—one written in English, one written in Hebrew, one written in Greek, and one written in symbols. Only four people knew all three languages; about one third knew Hebrew and English.

Michael discovered that familiarity does play a role in vision testing and that the most accurate way to test eyesight is by using pictures instead of letters.
