The Richman Face Dot Test™

The Richman Face Dot Test (RFDT™) is a test for visual acuity in difficult-to-test pre-verbal or nonverbal infants and children with low cognitive or developmental functioning levels. The face is an easily recognized target and provides a strong attention stimulus for low functioning patients. The test employs the use of contrast sensitivity in a forced choice testing procedure. The results may be converted into an approximate visual acuity based on the testing distance. The set includes three paddles that can be used at different test distances to approximate visual acuity. Distance chart is on back of test paddle. Instructions for the different testing methods are also included.
