ABSTRACT:
A lens system and optical devices that provide enhanced vision correction are disclosed. The lens system includes an electro-active layer that provides correction of at least one higher order aberration. The higher order correction changes dynamically based on a user of the lens system's needs, such as a change by the user's gaze distance, pupil size, or changes in tear film following blinking, among others. Optical devices are also described that use these and other lens systems to provide correction of higher order aberrations. An optical guide is also described that guides the user's line of sight to see through a lens region having a correction for a higher order aberration.
