1. An optical apparatus comprising:
eye-tracking means;
a dominant-eye optical element and a non-dominant-eye optical element for a dominant eye and a non-dominant eye of a user, respectively, wherein each of the dominant-eye optical element and the non-dominant-eye optical element comprises:
at least a first substrate and a second substrate that are optically transparent;
an active material encased between the first substrate and the second substrate; and
controlling means for controlling the active material to generate one or more optical powers; and
a processor configured to:
process eye-tracking data, collected by the eye-tracking means, to determine a gaze direction of the dominant eye and a gaze direction of the non-dominant eye;
detect when a given criteria is satisfied, wherein the given criteria is satisfied when at least one of the following is true:
the gaze direction of the dominant eye and the gaze direction of the non-dominant eye has not converged for at least a predefined time period,
the gaze direction of the dominant eye and the gaze direction of the non-dominant eye has not converged within a predefined error margin from each other; and
when it is detected that the given criteria is satisfied, activate an amblyopia treatment mode of the optical apparatus, and generate respective drive signals to drive the controlling means of the dominant-eye optical element and the controlling means of the non-dominant-eye optical element to perform any of:
(i) produce, at the dominant-eye optical element, an optical power that is different from a predefined dominant-eye optical power corresponding to the dominant eye, whilst producing, at the non-dominant-eye optical element, a predefined non-dominant-eye optical power corresponding to the non-dominant eye,
(ii) produce the predefined dominant-eye optical power and the predefined non-dominant eye optical power at the dominant-eye optical element and the non-dominant-eye optical element, respectively, whilst applying a prism correction on the dominant-eye optical element to optically shift light, incident thereupon and emanating from a region of a real-world environment at which the non-dominant eye is gazing, to be incident on a fovea of the dominant eye.
