METHOD AND APPARATUS FOR SPATIALLY LOCATING LENS COMPONENTS ON A LENS PRECURSOR

摘要

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.

主权项

1. 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.
