Enhanced electro-active lens system
View Patent ↗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.
1. A lens system comprising at least one electro-active layer that provides correction of at least one higher order aberration, wherein the provided higher order correction dynamically changes in response to a user's needs while looking through the lens system, wherein the provided higher order correction changes dynamically in response to a change in pupil size by the user looking through the lens system.
2. The lens system of claim 1 , further comprising a photo-detector, wherein the photo-detector is configured to detect the diameter of a pupil of the user looking through the lens system.
3. The lens system of claim 1 , applied to one of the group consisting of a telescope, a microscope, bio-microscope, ophthalmoscope, camera, a rifle scope, binoculars, and a night scope.
4. A lens system comprising at least one electro-active layer that provides correction of at least one higher order aberration, wherein the provided higher order correction dynamically changes in response to a user's needs while looking through the lens system, wherein the provided higher order correction changes dynamically in response to a change in a tear film of the user's eye.
5. The lens system of claim 4 , applied to one of the group consisting of a telescope, a microscope, bio-microscope, ophthalmoscope, camera, a rifle scope, binoculars, and a night scope.
6. The lens system of claim 4 , comprising a photo-sensor, wherein the photo-sensor is configured to detect reflection of light off the cornea of an eye of the user looking through the lens system.
7. A lens system comprising at least one electro-active layer that provides correction of at least one higher order aberration, wherein the provided higher order correction dynamically changes in response to a use's needs while looking through the lens system, wherein the provided higher order correction changes dynamically in response to a change in ambient light conditions.
8. A lens system comprising at least one electro-active layer that provides correction of at least one higher order aberration, wherein the provided higher order correction dynamically changes in response to a user's needs while looking through the lens system, wherein the provided higher order correction changes dynamically in response to a blink of the user's eye when looking through the lens system.
9. The lens system of claim 8 , comprising a photo-sensor, wherein the photo-sensor is configured to detect reflection of light off the cornea of an eye of the user looking through the lens system.
