Determination of visual susceptibility to digital screen use

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 and one or more sensors, the one or more programs including instructions for:

• executing a visual assessment application, including displaying a user interface to create a 3D virtual environment;
• displaying visual content continuously for an extended duration of time in the 3D virtual environment, wherein the visual content is displayed with predefined display parameters associated with a screen usage;
• obtaining a stream of sensor data measured by the one or more sensors;
• determining a plurality of sequential user responses to the visual content based on the stream of sensor data;
• and
• applying at least a screen usage prediction model to generate a screen usage guidance profile for the user based on the plurality of sequential user responses.
