A display system for displaying a virtual object, the display system comprising: one or more processors; and one or more computer storage media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising: determining whether the virtual object is located within a loss-of-fusion zone associated with the user; determining whether the user is verging at a point within the loss-of-fusion zone; refraining from displaying the virtual object within the loss-of-fusion zone if the virtual object is determined to be located within the loss-of-fusion zone and the user is verging at the point within the loss-of-fusion zone; determining whether the virtual object is located within an accommodation-vergence mismatch discomfort zone associated with the user, the accommodation-vergence mismatch discomfort zone extending beyond the loss-of-fusion zone and having accommodation-vergence mismatches exceeding a threshold value; determining whether a vergence point of the user is within the accommodation-vergence mismatch discomfort zone; and limiting displaying of the virtual object to the user if: the virtual object is located within the accommodation-vergence mismatch discomfort zone; and the vergence point of the user is within the accommodation-vergence mismatch discomfort zone. one or more processors; and one or more computer storage media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising: determining whether the virtual object is located within a loss-of-fusion zone associated with the user; determining whether the user is verging at a point within the loss-of-fusion zone; refraining from displaying the virtual object within the loss-of-fusion zone if the virtual object is determined to be located within the loss-of-fusion zone and the user is verging at the point within the loss-of-fusion zone; determining whether the virtual object is located within an accommodation-vergence mismatch discomfort zone associated with the user, the accommodation-vergence mismatch discomfort zone extending beyond the loss-of-fusion zone and having accommodation-vergence mismatches exceeding a threshold value; determining whether a vergence point of the user is within the accommodation-vergence mismatch discomfort zone; and limiting displaying of the virtual object to the user if: the virtual object is located within the accommodation-vergence mismatch discomfort zone; and the vergence point of the user is within the accommodation-vergence mismatch discomfort zone. determining whether the virtual object is located within a loss-of-fusion zone associated with the user; determining whether the user is verging at a point within the loss-of-fusion zone; refraining from displaying the virtual object within the loss-of-fusion zone if the virtual object is determined to be located within the loss-of-fusion zone and the user is verging at the point within the loss-of-fusion zone; determining whether the virtual object is located within an accommodation-vergence mismatch discomfort zone associated with the user, the accommodation-vergence mismatch discomfort zone extending beyond the loss-of-fusion zone and having accommodation-vergence mismatches exceeding a threshold value; determining whether a vergence point of the user is within the accommodation-vergence mismatch discomfort zone; and limiting displaying of the virtual object to the user if: the virtual object is located within the accommodation-vergence mismatch discomfort zone; and the vergence point of the user is within the accommodation-vergence mismatch discomfort zone. the virtual object is located within the accommodation-vergence mismatch discomfort zone; and the vergence point of the user is within the accommodation-vergence mismatch discomfort zone. <EOS>
