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 one error of a patient's eye selected from the group consisting of spherical error and cylindrical error;
- and
- the second layer being configured to substantially correct at least one aberration or at least one error of the patient's eye.
