Determination of sightline-based corrective measures of eyewear

A non-transitory computer readable storage medium, storing one or more programs for execution by one or more processors of an electronic device having an HMD, the one or more programs including instructions for:

• executing a visual assessment application, including displaying a user interface to create a 3D virtual environment;
• identifying a plurality of horizontal lines of sight;
• for each horizontal line of sight:
• rendering a respective visual stimulus on the respective horizontal line of sight;
• obtaining a user response to the respective visual stimulus;
• and
• dynamically adjusting stimulus parameters of the respective visual stimulus based on the user response;
• and
• based on the stimulus parameters associated with each horizontal line of sight, determining an eyewear prescription of an eyewear for a user associated with the electronic device, the eyewear prescription including prescription parameters corresponding to the plurality of horizontal lines of sight.
