Abstract
A multifocal system and a method thereof are provided. The multifocal system comprises a first adaptive lens assembly including a plurality of lenses arranged in optical series. The plurality of lenses includes at least one active liquid crystal (LC) lens having a plurality of optical states, such that the plurality of lenses provides a plurality of combinations of optical power, and the plurality of combinations of optical power provides a range of adjustment of optical power for the multifocal system. The multifocal system may include a second adaptive lens assembly configured to provide a plurality of combinations of optical power that is opposite to but having a same absolute value as the plurality of combinations of optical power provided by the first adaptive lens assembly.
