Determination of multifocal parameters of multifocal 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:

• determining a multifocal eyewear prescription of a user associated with the electronic device, wherein the multifocal eyewear prescription includes a multifocal parameter for a lens having a plurality of focal lengths;
• partitioning a field of view displayed on the user interface into a plurality of regions;
• displaying a visual stimulus successively in two distinct regions of the user interface;
• obtaining user response data captured by one or more sensors in response to the visual stimulus displayed in the two distinct regions;
• and
• based on the user response data, adjusting the multifocal parameter of the multifocal eyewear prescription.
