1. A mold for use in the manufacture of ophthalmic lenses comprisinga.) at least one mold half comprising a non-molding surface and a molding surface, wherein at least a portion of the molding surface is capable of being reversibly deformed; andb.) adjustment means for reversibly deforming the deformable portion of the molding surface, wherein the adjustment means is selected from the group consisting of a mechanical magnetic field deformation means, a micro-actuator, and combinations thereof. 2. The lens of claim 1, wherein the molding surface comprises one of the group consisting of a metal, a polymer, a metalized polymer, and combinations thereof. 3. The mold of claim 1, wherein the molding surface comprises one of the group consisting of aluminum, gold, brass, nickel, and combinations thereof. 4. The mold of claim 1, wherein the molding surface comprises one of the group consisting of a polyolefin polymer, polyethylene terphthalate, a silicone polymer, an electro-active polymer, a shape-memory polymer, a ceramic, a shape-memory alloy, and combinations thereof. 5. The mold of claim 1, wherein the molding surface comprises polyolefin polymers. 6. The mold of claim 5, wherein the polyolefin polymer is polyethylene or polypropylene. 7. The mold of claim 1, wherein the deformable portion of the molding surface is a membrane. 8. The mold of claim 7, wherein the membrane if of a thickness of about 0.5 to about 5000 microns. 9. The mold of claim 1, wherein the adjustment means is a micro-actuator. 10. The mold of claim 9, wherein the micro-actuator is selected from the group consisting of a piezo-electric actuator, a micro-motorized actuator, a hydraulic micro-actuator, a magneto-restrictive micro-actuator, an electrostatic micro-actuator, and combinations thereof. 11. The mold of claim 1, wherein the adjustment means comprises a mechanical magnetic field deformation means. 12. The mold of claim 11, wherein the deformation means comprises a first and a second magnetic surface. 13. A process for manufacturing an ophthalmic lens comprising the steps of:a.) providing a mold, at least one half of the mold comprising, consisting essentially of and consisting of (i.) a non-molding surface and a molding surface, wherein at least a portion of the molding surface is capable of being reversibly deformed and (ii.) adjustment means for reversibly deforming the deformable portion of the molding surface, wherein the adjustment means is selected from the group consisting of a mechanical magnetic field deformation means, a micro-actuator, and combinations thereof;b.) contacting the adjustment means with the non-molding surface in a manner to deform the deformable portion of the molding surface to a shape suitable for imparting one or more optical characteristics onto a lens surface;c.) depositing a lens-forming material on the molding surface mold; andd.) curing the lens-forming material under conditions suitable to form the ophthalmic lens. 14. The process of claim 13, wherein curing is carried out thermal cure, irradiation cure, chemical cure, electromagnetic radiation cure, or combinations thereof. 15. The method of claim 13, wherein curing is carried out using ultraviolet light. 16. A method for producing customized ophthalmic lenses comprising the steps of:a.) transmitting to a lens manufacturer lens order information wherein the information is one of corneal topographic measurements, low order ocular aberrations, high order ocular aberrations, or combinations thereof; andb.) manufacturing by the lens manufacturer the lenses using a mold for comprising, consisting essentially of, and consisting of i.) at least one mold half comprising, consisting essentially of and consisting of a non-molding surface and a molding surface, wherein at least a portion of the molding surface is capable of being reversibly deformed and ii.) adjustment means for reversibly deforming the deformable portion of the molding surface, wherein the adjustment means is s elected from the group consisting of a mechanical magnetic field deformation means, a micro-actuator, and combinations thereof. 17. The method of claim 16, wherein transmitting is performed by a customer using a computer system and the information is transmitted to a lens manufacturer's server system. 18. The method of claim 16, further comprising the step of: c.) delivering by the lens manufacturer directly to the customer the lenses. 19. The method of claim 16, wherein the information is corneal topographic measurements, Zemike coefficients, or combinations thereof. 20. The method of claim 17, wherein the information is corneal topographic measurements, Zernike coefficients, or combinations thereof.
