Binary Choice Self-Testing
For the first time this patented method allows 1 or 2 choice to signal a response, which removes calling out letters or numbers for an examiner to record, which allows complete automation and independence of language obstacles.
Testing: Corrective lenses?
Only if the patient wears glasses.
Test each eye at the same distance from the screen (16 inches). When visual acuity is different in the right and left eyes or if acuity is less than 20/30, refer to a vision care specialist.
