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.
Claims21
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 first and third layers being configured to substantially correct at least a first aberration of a patient's eye selected from the group consisting of spherical aberration and cylindrical aberration;
- and
- the second layer being configured to substantially correct at least a second aberration of the patient's eye.
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 first and third layers being configured to correct a first portion of an aberration of a patient's eye to within 0.25 diopters;
- and
- the second layer being configured to correct a second portion of the aberration of the patient's eye.
