What is claimed is: 1. 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 second layer comprising a plurality of vision zones which simultaneously comprise first and second differing powers, each vision zone being configured to correct at least part of a plurality of different errors and aberrations of the patient's eye; and the second layer further comprising at least one transition zone configured to provide a smooth transition between at least two of the plurality of zones. 2. The eyeglass lens of claim 1, in which the plurality of vision zones comprises at least a first vision zone and a second vision zone, each of the first vision zone and the second vision zone being independently selected from the group consisting of a vision zone configured to correct at least part of a far vision error and aberration, and a vision zone configured to correct at least part of a near vision error and aberration. 3. The eyeglass lens of claim 1, further comprising a normal vision zone. 4. The eyeglass lens of claim 1, in which the plurality of vision zones comprises at least two vision zones, each of which is independently configured to substantially correct at least an aberration. 5. The eyeglass lens of claim 1, in which the plurality of vision zones comprises at least two vision zones, each of which is independently configured to substantially correct at least an error. 6. The eyeglass lens of claim 1, in which 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 errors and aberrations of the patient's eye for a first gazing angle and a second vision zone configured to correct at least part of the plurality of different errors and aberrations of the patient's eye for a second gazing angle. 7. The eyeglass lens of claim 1, that is a multi-focal lens. 8. The eyeglass lens of claim 1, that comprises a reading lens correction. 9. The eyeglass lens of claim 1, that is a progressive addition lens. 10. The eyeglass lens of claim 1, in which at least one of the first lens and the second lens is configured to substantially correct an error. 11. The eyeglass lens of claim 1, in which at least one of the first lens and the second lens is configured to correct at least part of an error.
