System, apparatus, and method for correcting vision using an electro-active lens

Abstract

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.

1 - 16 . (canceled)  
   
   
       17 . An eyeglass lens, comprising: 
 a first layer comprising a first lens having a constant index of refraction and;    a second layer comprising a material having a varying index of refraction; and    a third layer comprising a second lens, the second layer being sandwiched between the first layer and the third layer;    the second layer comprising a plurality of vision zones, each vision zone being configured to correct at least part of a plurality of different aberrations of the patient's eye; and    the second layer further comprising at least one transition zone configured to provide a smooth transition between at least two of the plurality of zones.    
   
   
       18 . The eyeglass lens of  claim 17 , in which the plurality of vision zones comprises at least a first vision zone and a second vision zone, each of the first vision zone and the second vision zone being independently selected from the group consisting of a vision zone configured to correct at least part of a low order aberration; 
 a vision zone configured to correct at least part of a high order aberration;    a vision zone configured to correct at least part of a far vision aberration, and    a vision zone configured to correct at least part of a near vision aberration    
   
   
       19 . The eyeglass lens of  claim 17 , further comprising a normal vision zone.  
   
   
       20 . The eyeglass lens of  claim 17 , in which the plurality of vision zones comprises at least two vision zones, each of which is independently configured to substantially correct at least a high order aberration.  
   
   
       21 . The eyeglass lens of  claim 17 , in which the plurality of vision zones comprises at least two vision zones, each of which is independently configured to substantially correct at least a low order aberration.  
   
   
       22 . The eyeglass lens of  claim 17 , in which the at least one transition zone is configured to provide a smooth transition between a first vision zone configured to correct at least part of the plurality of different aberrations of the patient's eye for a first gazing angle and a second vision zone configured to correct at least part of the plurality of different aberrations of the patient's eye for a second gazing angle.  
   
   
       23 . The eyeglass lens of  claim 22 , in which the plurality of different aberrations comprises at least one aberration selected from the group consisting of low order aberration and high order aberration.  
   
   
       24 . The eyeglass lens of  claim 17 , that is a multi-focal lens.  
   
   
       25 . The eyeglass lens of  claim 17 , that is a reading lens.  
   
   
       26 . The eyeglass lens of  claim 17 , that is a progressive addition lens.  
   
   
       27 . The eyeglass lens of  claim 17 , in which at least one of the first lens and the third lens is configured to substantially correct a low order aberration.  
   
   
       28 . The eyeglass lens of  claim 17 , in which at least one of the first lens and the third lens is configured to correct at least part of a low order aberration.  
   
   
       29 . The eyeglass lens of  claim 28 , in which the second layer is configured to correct a least part of the low order aberration.  
   
   
       30 . The eyeglass lens of  claim 28 , in which the second layer is configured to correct a least part of a high order aberration.
