Abstract
A method to self-test vision of a user for use with a handheld vision tester includes receiving image data of the user's face, determining dimensions of the user's face based on the received image data, computing a user viewing distance based on the determined dimensions, displaying a vision test based on the computed user viewing distance, receiving user input responses to the vision test, and outputting results of the vision test from the user input responses.
