Patent ID: 7988284

Claim:
An eyeglass lens, comprising: a first layer comprising a first lens of substantially uniform thickness, the lens having a constant index of refraction; a second layer comprising a material having an index of refraction that can be changed by exposure to curing radiation; and a third layer comprising a second lens, the second layer being sandwiched between the first layer and the third layer; wherein the first and third layers are configured to substantially correct at least a first aberration of a patient's eye, wherein the first aberration of the patient's eye is a lower order aberration, wherein the lower order aberrations is selected from the group consisting of spherical aberration and cylindrical aberration, and the second layer is configured to substantially correct at least a second aberration of the patient's eye, wherein the second aberration of the patient's eye is a higher order aberration, wherein a higher order aberration comprises at least one selected from the group consisting of coma, trefoil, quadrafoil, spherical aberration, and secondary astigmatism.
