What is claimed is: 1. A method of preparing an eyeglass lens, comprising: placing one or more job tickets in a lens curing apparatus, wherein one or more of the job tickets includes prescription information, the lens curing apparatus comprising: a first lens curing unit comprising an activating light source, wherein the first lens curing unit is configured to produce activating light directed toward a mold assembly during use; a second lens curing unit comprising an activating light source and a heating system, wherein the activating light source is configured to direct activating light toward the mold assembly during use, wherein the heating system is configured to heat the interior of the second lens curing unit during use; and a conveyor system wherein the conveyor system is configured to convey a mold assembly through the first lens curing unit into and through the second lens curing unit during use; reading the prescription information from one or more of the job tickets; placing a mold assembly comprising a lens forming composition into the first lens curing unit; operating the first lens curing unit to produce curing conditions to at least partially cure the lens forming composition, the curing conditions being determined in response to the prescription information, and wherein the curing conditions comprise one or more doses of light; transferring the mold assembly to the second lens curing unit; and operating the second lens curing unit to apply light and heat to the mold assembly. 2. The method of claim 1, wherein reading the prescription information comprises reading the prescription information from a barcode. 3. The method of claim 1, further comprising forming a job ticket with prescription information, wherein the prescription information is entered into a job ticket printing device from an input device, wherein the input device is operable by a user to enter prescription information. 4. The method of claim 1, wherein the prescription information comprises a sphere power, a cylinder power, and a lens location. 5. The method of claim 1, wherein the prescription information further comprises a monomer type and a lens type. 6. The method of claim 1, wherein the prescription information comprises a sphere power, a cylinder power, an add power and a lens location. 7. The method of claim 1, wherein operating the lens curing apparatus comprises controlling the activating light source to produce the curing conditions for the eyeglass lens. 8. The method of claim 1, wherein the activating light source comprises a plurality of light sources, and wherein controlling the activating light source comprises controlling each of the plurality of light sources independently. 9. The method of claim 1, wherein the lens curing apparatus further comprises an anneal unit, and further comprising controlling the anneal unit, the anneal unit being configured to apply heat to a demolded eyeglass lens. 10. The method of claim 1, wherein operating the lens curing apparatus comprises controlling the duration of time that the activating light source remains on. 11. The method of claim 1, wherein the conveyor system comprises a continuous flexible member extending from a first lens curing unit of the lens curing apparatus through a second lens curing unit of the lens curing apparatus, wherein the flexible member is configured to interact with the mold assembly to convey the mold assembly through the first lens curing unit, to the second lens curing unit, and through the second lens curing unit. 12. The method of claim 1, wherein the conveyor system comprises two discrete conveyors, wherein the first conveyor is configured to convey the mold assembly from a first lens curing unit of the lens curing apparatus to a second lens curing unit of the lens curing apparatus, and wherein the second conveyor is configured to convey the mold assembly through the second lens curing unit. 13. The method of claim 1, wherein the conveyor system comprises a flexible member configured to interact with a mold assembly, and wherein the flexible member is coupled to a motor configured to move the flexible member through the conveyor system. 14. The method of claim 1, further comprising placing the mold assembly in a mold holder wherein the mold assembly holder comprising a body and an indentation formed in the body, wherein the indentation is complementary to the shape of the mold assembly. 15. The method of claim 1, further comprising placing the mold assembly in a mold holder, wherein the mold assembly holder comprises a ridge disposed on the bottom surface, wherein the ridge is configured to interact with the conveyor system. 16. The method of claim 1, wherein the activating light source is an ultraviolet light. 17. The method of claim 1, wherein the activating light source has a peak light intensity at a range of about 385 nm to about 490 nm. 18. The method of claim 1, wherein operating the lens curing apparatus comprises determining a speed of the conveyor. 19. The method of claim 1, wherein the lens curing apparatus comprise a filter disposed directly adjacent to the activating light source, the filter being configured to manipulate an intensity of the activating light emanating from the activating light source. 20. The method of claim 1, further comprising monitoring one or more temperatures of the lens curing apparatus, and wherein a speed of the conveyor is detennined in response to one or more of the temperatures.
