1. A method of operating an optical system, the method comprising:
generating, by a projector of the optical system, a collimated pixel beam associated with a virtual object to be displayed;
providing the collimated pixel beam to a light modifying device, wherein the light modifying device is configured to switch between:
passing the collimated pixel beam through the light modifying device without modification to the collimated pixel beam; and
modifying the collimated pixel beam to generate a modified pixel beam;
injecting either the collimated pixel beam or the modified pixel beam into an eyepiece of the optical system; and
outputting either the collimated pixel beam or the modified pixel beam from the eyepiece toward a user side of the optical system.
