Abstract
This invention provides for Spatial Placement of Lens Components by Spatially Polymerizing portions of Fluent Lens Reactive Media using one or more controlled projections of actinic radiation to a Lens Precursor device. More specifically, the Lens Components Spatially Placed can include one or more of: electrical components, pigment particles, coatings, and active agents. The control of the actinic radiation can include the use of a voxel based lithography method using a digital micromirror device, a laser, or the use of a photomask.
Claims23
An apparatus for polymerizing a flowable reactive mixture portion in contact with a non-fluent ophthalmic object with at least one optical surface and placing ophthalmic lens components onto at least a portion of the flowable reactive mixture portion, the apparatus comprising:
- a substrate comprising an arcuate optical quality surface;
- wherein at least a portion of said arcuate optical quality surface supports the non-fluent ophthalmic object with at least one optical surface in contact with the flowable reactive mixture portion;
- a source of radiation controllable to polymerize one or more portions of the flowable reactive mixture portion in contact with the non-fluent ophthalmic object with at least one optical surface;
- and
- a deposition tool controlled by a processor operable to deposit one or more ophthalmic lens components onto at least a portion of the flowable reactive mixture portion in contact with a non-fluent ophthalmic object with at least one optical surface.
A method of manufacturing an ophthalmic lens, the method comprising:
- forming a non-fluent ophthalmic object with at least one optical surface in contact with a flowable reactive mixture;
- projecting controlled actinic radiation to polymerize portions of said flowable reactive mixture;
- and
- depositing one or more ophthalmic lens components onto at least a portion of said flowable reactive mixture.
