Classification: CPC G | IPC G

Claim 0:
1. An optical system comprising:
a left optical stack configured to output left virtual image light toward a user side of the optical system, the left optical stack having first and second left eyepieces associated with first and second focal planes, respectively;
a right optical stack configured to output right virtual image light toward the user side of the optical system, the right optical stack having first and second right eyepieces associated with the first and second focal planes, respectively, wherein each of the left optical stack and the right optical stack is configured to switch between displaying virtual content at the first focal plane or the second focal plane; and
a processing module configured to perform operations comprising:
determining whether or not an activation condition is satisfied, wherein the activation condition is determined to be satisfied by determining that eye tracking data is unavailable while a user is using the optical system; and
in response to determining that the activation condition is satisfied, activating a monovision display mode associated with the optical system, wherein activating the monovision display mode includes:
causing the left optical stack to display the virtual content solely at the first focal plane by outputting the left virtual image light at the first left eyepiece and-causing the right optical stack to display the virtual content solely at the second focal plane by outputting the right virtual image light at the second right eyepiece; or
causing the left optical stack to display the virtual content solely at the second focal plane by outputting the left virtual image light at the second left eyepiece and causing the right optical stack to display the virtual content solely at the first focal plane by outputting the right virtual image light at the first right eyepiece.
