Abstract: A method and system for determining visual related physical conditions of a user of a display device, determined from the user's responses to a selection of visual-tasks. A dataset is provided for correlating the user's responses with the corresponding scores, so that by measuring the degree of correlation between the user's scores and a predetermined combination of the corresponding scores, the user's visual physical condition can be determined. A system is also provided, including a user device as well as a remote server for providing visual acuity and related testing to detect certain vision deficiencies and visual related physical conditions. In addition, a user device application is provided.

Abstract: Methods for presenting dynamic images to a user, configured to evaluate and/or improve the user's foveal and/or peripheral visual acuity. Dynamic computer games are popular, but the moving images of prior art dynamic computer games are not suitable for improving visual acuity. To overcome this restriction, embodiments of the present invention analyze user's responses to the moving images to determine a change in the user's visual acuity, and responsively adjust parameters of the moving images, such as speed, direction of motion, orientation, crowding, contrast, and spatial frequency, in order to improve the user's visual acuity.
