Eyeglass manufacturing method using variable index layer
View Patent ↗An eyeglass lens and 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.
1. An eyeglass lens, comprising:
a first layer comprising a first lens;
a second layer comprising a material having a varying index of refraction, wherein the index of refraction of the material is variable by radiation curing; and
wherein the second layer further comprises 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 at least one transition zone configured to provide a smooth transition between at least two of the plurality of zones, wherein 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.
2. An eyeglass lens, comprising:
a first layer comprising a first lens;
a second layer comprising a material having a varying index of refraction, wherein the index of refraction of the material is variable by radiation curing; and
wherein the second layer further comprises 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 at least one transition zone configured to provide a smooth transition between at least two of the plurality of zones, wherein 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 is configured to correct at least part of the plurality of different aberrations of the patient's eye for a second gazing angle.
3. An eyeglass lens, comprising:
