Eyeglass manufacturing method using variable index layer

Abstract

An eyeglass lens and manufacturing method using a variable refractive index material, such as epoxy. In one embodiment, a method of making an eyeglass lens includes: imaging a patient's eye to determine a wavefront prescription for the patient; and curing the lens based on the wavefront prescription such that the wavefront guided lens corrects for aberrations over the lens for a plurality of gazing angles of the patient.

1 . A method of treating a person with retinal dysfunction which comprises providing the patient with spectacle lenses that correct for low order aberrations and at least one high order aberration.  
     
     
         2 . The method of  claim 1  wherein retinal dysfunction is macular degeneration and the spectacle lenses comprise a layer of a curable material that has been cured to provide a layer having a variable refractive index which corrects the at least one high order aberration.  
     
     
         3 . The method of  claim 1  wherein the curable material is an epoxy.  
     
     
         4 . The method of  claim 4  wherein the epoxy is cured by exposure to ultraviolet radiation.  
     
     
         5 . A retinal dysfunction-correcting spectacle lens which comprises a low order aberration-correcting lens and a layer of a curable material that has been cured to provide a layer of variable refractive index which corrects at least one high order aberration and said high order aberration correction provides improved vision to a person with the retinal dysfunction.  
     
     
         6 . The spectacle lens of  claim 5  wherein the retinal dysfunction is macular degeneration.  
     
     
         7 . The spectacle lenses of  claim 6  wherein the curable material is an epoxy.  
     
     
         8 . The spectacle lens of  claim 7  wherein the epoxy is cured by exposure to ultraviolet radiation.
