1. A method of operating an optical system, the method comprising:
defining, based on a vergence-accommodation conflict (VAC) limit, a delimited zone as a function of distance from the optical system, the delimited zone having at least one distance threshold;
determining a virtual distance of a virtual depth plane from the optical system at which a virtual object is to be displayed;
determining whether the virtual distance is outside the delimited zone by comparing the virtual distance to the at least one distance threshold;
generating, by a projector of the optical system, a collimated pixel beam associated with the virtual object;
based on determining that the virtual distance is outside the delimited zone, modifying the collimated pixel beam to generate a modified pixel beam, wherein modifying the collimated pixel beam includes at least one of:
converging the collimated pixel beam; or
reducing a diameter of the collimated pixel beam;
injecting the modified pixel beam into an eyepiece of the optical system; and
outputting the modified pixel beam from the eyepiece toward an eye of a user.
