Multiple-wavelength lens forming system and method

A method for forming a contact lens having an optic zone comprising:

• forming a Lens Precursor by
• obtaining a Lens Reactive Mixture including a UV blocker and a photoinitiator;
• submerging a convex optical quality surface of a forming optic in a reservoir containing said Lens Reactive Mixture;
• projecting a first Actinic Radiation having a first spectrum of wavelengths through pre-selected regions of said forming optic, wherein the first spectrum of wavelengths is not attenuated by said UV blocker and is within an initiator absorbance range of said photoinitiator;
• wherein said pre-selected regions correspond to locations of said contact lens to be formed having a thickness greater than a pre-determined thickness and that are not located in the optic zone, and wherein said first Actinic Radiation is selectively controlled to selectively polymerize or partially polymerize said Lens Reactive Mixture on a Voxel by Voxel basis at said pre-selected regions;
• and
• projecting a second Actinic Radiation having a second different spectrum of wavelengths through said forming optic over a second region corresponding to an entirety of said contact lens to be formed, wherein said second spectrum of wavelengths is at least partially attenuated by said UV blocker and is within said initiator absorbance range of said photoinitiator, wherein said second Actinic Radiation is selectively controlled to selectively polymerize or partially polymerize said Lens Reactive Mixture on a Voxel by Voxel basis across said forming optic;
• wherein a time required to form said Lens Precursor is less than a time required to form said Lens Precursor using only said second Actinic Radiation;
• removing said forming optic and formed Lens Precursor from said Lens Reactive Mixture;
• applying a Fixing Radiation to form said contact lens.
