ABSTRACT:
An eyeglass manufacturing method using epoxy aberrator includes two lenses with a variable index material, such as epoxy, sandwiched in between. The epoxy is then cured to different indexes of refraction that provide precise corrections for the patient's wavefront aberrations. The present invention further provides a method to produce an eyeglass that corrects higher order aberrations, such as those that occur when retinal tissue is damaged due to glaucoma or macular degeneration. The manufacturing method allows for many different applications including, but not limited to, supervision and transition lenses.
