Abstract
An optical apparatus includes eye-tracking means, an active optical element per eye including an active material, and means for controlling the active material to generate optical powers. Gaze directions of a user's eyes are determined. When it is detected, based on the gaze directions, that the user is looking through a predefined portion of the active optical element, a drive signal is generated to drive said means to control the active material to produce a predefined optical power. When it is detected that the user's gaze is moving towards a periphery of the predefined portion, at least one other drive signal is generated to drive said means to control the active material to produce at least one intermediate optical power lying in a range between a zero optical power and the predefined optical power.
