A method of determining an eyeglass prescription for correcting a user's vision is provided. The method includes: prompting the user for selective parameters; configuring an eye chart for display based on the selective parameters; receiving sizing input from the user if the user increases or decreases the size of the eye chart until the eye chart appears clear; reconfiguring the eye chart based on the received sizing input; comparing the reconfigured eye chart to the configured eye chart; and determining the eyeglass prescription for correcting the user's vision based on a comparison between the reconfigured eye chart and the configured eye chart. A system for determining an eyeglass prescription for correcting a user's vision is also provided. The system includes a parameter module, a configure module, a receive module, a reconfigure module, a compare module, and a determine module. The parameter module prompts the user for selective parameters. The configure module configures the eye chart for display based on the selective parameters. The receive module receives sizing input from the user as the user increases or decreases the size of the eye chart until the eye chart appears clear. The reconfigure module reconfigures the eye chart based on the received sizing input. The compare module compares the reconfigured eye chart to the configured eye chart. The determine module determines the eyeglass prescription for correcting the user's vision based on comparison between the reconfigured eye chart and the configured eye chart.
