Abstract

A system, a computer readable storage medium including programs, and a computer-implemented method for displaying objects in a graphical user interface of a device are described. A vision test is presented in the graphical user interface of the device, the vision test including vision test objects used to test a visual acuity level of a user of the device. Input is received from the user identifying the user's ability to see at least one vision test object in the vision test. Display settings corresponding to the input received from the user are identified. Objects in the graphical user interface are displayed based on the display settings.
