Enhanced electro-active lens system

Abstract

A lens system and optical devices that provide enhanced vision correction are disclosed. The lens system (100) includes an electro-active layer (105) 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.

Description

Background technique [0001] Many people, even those with good vision, have some vision defect that falls into the category of non-traditional refractive error, which prevents them from achieving optimal visual acuity. Unlike traditional refractive errors (ie, "nearsightedness" or "hypersightedness" and other types of problems commonly experienced by people with corrected vision), the effects of non-traditional refractive errors (eg, higher order aberrations) have an individual It can be very difficult to detect until it is identified, measured, and corrected during an eye exam, and with correction of these deviations, the individual has the opportunity to gain increased visual acuity. [0002] The effect of higher order aberrations may vary with environmental conditions, such as distance from the observed object or pupil size (based on observation distance and ambient light entering the pupil varies). Thus, lenses that provide fixed corrections for higher order aberrations st...

Problems solved by technology

Thus, lenses that provide fixed corrections for higher order aberrations still do not provide adequate correction to the individual except under certain conditions.
