First Claim
1. A method for testing visual acuity of a user using a computerized consumer device, the method comprising:
- initiating a visual acuity test to assess the visual acuity of a user using a computerized consumer device, the computerized consumer device comprising a display screen, a camera, a microphone, a speaker, a computer processor, and a memory, the user being a human subject;
determining, by the computerized device, a separation distance between a user and the computerized consumer device based on an image size of a physical feature of the person using imagery of the user taken by the camera of the computerized consumer device;
instructing, by the computerized consumer device, the user to adjust the separation between the user and the computerized consumer device, and instructing the user that a predetermined separation distance range is achieved;
presenting, by the computerized consumer device, a visual acuity test to the user without use of a refractor lens assembly, wherein presenting the visual acuity test comprises displaying predetermined optotypes at the display screen of the computerized consumer device for the user to perceive;
recording, at the computerized consumer device, spoken identifications by the user of perceptions of the predetermined optotypes via the microphone of the computerized consumer device, and providing real-time feedback to the user of detection of the spoken indications by the computerized consumer device;
carrying out speech recognition on the user'"'"'s spoken identifications to generate converted text corresponding to the spoken identifications;
comparing recognized words of the converted text to permissible words corresponding to the predetermined optotypes using a lookup table;
determining a score for visual acuity test taken by the user based on said comparing; and
determining whether the user passed the visual acuity test based on the score.

Abstract
Systems and methods for assessing the visual acuity of person using a computerized consumer device are described. The approach involves determining a separation distance between a human user and the consumer device based on an image size of a physical feature of the user, instructing the user to adjust the separation between the user and the consumer device until a predetermined separation distance range is achieved, presenting a visual acuity test to the user including displaying predetermined optotypes for identification by the user, recording the user'"'"'s spoken identifications of the predetermined optotypes and providing real-time feedback to the user of detection of the spoken indications by the consumer device, carrying out voice recognition on the spoken identifications to generate corresponding converted text, comparing recognized words of the converted text to permissible words corresponding to the predetermined optotypes, determining a score based on the comparison, and determining whether the person passed the visual acuity test.
