1. A method of customizing vision correction, comprising: measuring optical aberration data of a patient's eye;calculating a lens definition based on the optical aberration data, wherein calculating the lens definition comprises calculating a correction of at least one low order aberration and at least one high order aberration and is based at least partly on the patient's pupil size; andfabricating a lens based on the lens definition. 2. The method of claim 1, wherein the lens definition further comprises a low order prescription and wherein the low order prescription is defined in terms of sphere, cylinder, and axis. 3. The method of claim 1, wherein calculating the lens definition is further based on at least one of a patient's vertex distance, pupil distance, gaze, x-y tilt, color preference, spectral tint preference, photochromic preference, ultra-violet coating preference, anti-reflective coating preference, or patient wear preference. 4. The method of claim 1, wherein the optical aberration data comprises a wavefront aberrometer to determine a wavefront refraction measurement of the patient's eye. 5. The method of claim 1, wherein calculating the lens definition further comprises utilizing a metric to provide a modified low order prescription. 6. The method of claim 5, wherein the modified low order prescription is applied to a lens blank selected from the group consisting of a single layer lens blank and a multilayer lens assembly. 7. The method of claim 6, wherein a lens is formed by contouring the lens blank. 8. The method of claim 7, wherein contouring involves freeform processing, generating, polishing, and laser ablating the lens blank. 9. The method of claim 6, wherein the lens blank is a multilayer lens assembly comprising a photosensitive layer sandwiched between two ophthalmic lenses and wherein the photosensitive layer is cured using light to produce one selected from the group consisting of a uniform refractive index across the entire lens and a selective refractive index change over a small dimension of the lens. 10. The method of claim 1, further comprising one selected from the group of (1) measuring the optical data, calculating the lens definition, and fabricating the lens at the same location and (2) measuring the optical data and calculating the lens definition at a first location and fabricating the lens at a second location. 11. A correcting lens fabricated based on a lens definition, wherein the lens definition is determined by: measuring optical aberration data of a patient's eye; andcalculating the lens definition based on the optical aberration data, wherein calculating the lens definition comprises calculating a correction of at least one low order aberration and at least one high order aberration and is based at least partly on the patient's pupil size. 12. The correcting lens of claim 11, wherein the lens definition further comprises a low order prescription and wherein the low order prescription is defined in terms of sphere, cylinder, and axis. 13. The correcting lens of claim 11, wherein the lens definition is further based on at least one of a patient's vertex distance, pupil distance, gaze, x-y tilt, color preference, spectral tint preference, photochromic preference, ultra-violet coating preference, anti-reflective coating preference, or patient wear preference. 14. The correcting lens of claim 11, wherein the optical aberration data comprises a wavefront aberrometer to determine a wavefront refraction measurement of the patient's eye. 15. The correcting lens of claim 11, wherein calculating the lens definition further comprises utilizing a metric to provide a modified low order prescription. 16. The correcting lens of claim 15, wherein the modified low order prescription is applied to a lens blank selected from the group consisting of a single layer lens blank and a multilayer lens assembly. 17. The correcting lens of claim 16, wherein a lens is formed by contouring the lens blank. 18. The correcting lens of claim 17, wherein contouring involves freeform processing, generating, polishing, and laser ablating the lens blank. 19. The correcting lens of claim 16, wherein the multilayer lens assembly comprises a photosensitive layer sandwiched between two ophthalmic lenses and wherein the photosensitive layer is cured using light to produce one selected from the group consisting of a uniform refractive index across the entire lens and a selective refractive index change over a small dimension of the lens. 20. The correcting lens of claim 11, further comprising fabricating a lens based on the lens definition and further comprising one selected from the group of (1) measuring the optical data, calculating the lens definition, and fabricating the lens at the same location and (2) measuring the optical data and calculating the lens definition at a first location and fabricating the lens at a second location.
