Enhanced electro-active lens system
First Claim
1. A lens having an optical power, comprising:
- a sensor adapted for sensing an ambient light and producing a signal based on said sensed ambient light; and
a controller operably connected to said sensor, wherein said controller is adapted for adjusting the optical power of the lens based on said signal from said sensor and the controller is further adapted for adjusting the optical power of the lens to one of a plurality of optical prescriptions of a wearer of the lens based upon an intensity of said ambient light.

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.
