Abstract
An optical device including an active programmable lens having an adjustable optical power depending on a prescription of a wearer and being relative to a vision distance and/or direction of an eye of the wearer, a vision sensor adapted to measure vision data relating to the vision distance and/or direction of the eye, and an optical power controller that includes a memory storing computer executable instructions and adapted to store measured vision data and two predetermined optical power states corresponding to an optical power relative to a range of vision distance and/or direction of the eye, and a processor for executing the stored computer executable instructions, which include instructions for adjusting the adjustable optical power between the predetermined optical power states with a resolution smaller than or equal to 0.25 D when the vision data passes from one range of vision distance and/or direction to another.
