Abstract
An optical apparatus includes means for determining an optical depth at which a user is looking, an active optical element per eye, controlling means for controlling an active material in the active optical element to generate one or more optical powers, and a processor. The processor is configured to process data, collected by the means for determining, to determine the optical depth at which the user is looking; detect when the optical depth at which the user is looking is greater than a predefined optical depth; and when it is detected that the optical depth is greater than the predefined optical depth, generate a drive signal to drive the controlling means to control the active material in a portion of the active optical element to produce a predefined optical power thereat, wherein the predefined optical power is a negative optical power.
