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.

A method to self-test vision of a user for use with a handheld vision tester, comprising:
- receiving image data of the user's face;
- determining dimensions of the user's face based on said received image data;
- computing a user viewing distance based on said determined dimensions;
- displaying a vision test based on said computed user viewing distance;
- receiving user input responses to the vision test;
- and
- outputting results of the vision test from said user input responses.
A handheld vision tester for vision self-testing by a user, comprising:
- a camera configured to receive image data of the user's face;
- a display configured to present a vision test to said user;
- and
- a control configured to allow said user to input responses to the vision test;
- wherein said handheld vision tester is configured to:
- determine dimensions of the user's face based on said received image data;
- compute a user viewing distance based on said determined dimensions;
- determine the vision test to present based on said computed user viewing distance;
- and
- output results of the vision test from said user input responses.
One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
- receive image data of the user's face;
- determine dimensions of the user's face based on said received image data;
- compute a user viewing distance based on said determined dimensions;
- display a vision test based on said computed user viewing distance;
- receive user input responses to the vision test;
- and
- output results of the vision test from said user input responses.
