Abstract: An optical element includes a glass substrate layer and an optical plastic layer. The optical plastic layer has a planar surface. A prescription surface may be formed in the optical plastic layer opposite the planar surface.

Abstract: Fabricating a prescription optical element include providing a glass substrate layer and coupling an optical plastic layer to the glass substrate layer. A prescription surfaces is formed on an eyeward side of the optical plastic layer that is opposite an object side of the optical plastic layer. The object side is a planar surface that overlays the glass substrate layer and the glass substrate layer has a glass thickness to provide rigidity to the prescription optical element.

Abstract: A method of fabricating a lens includes dispensing a first liquid optically-transmissive material into a first mold cavity and then curing the first liquid optically-transmissive material to form a first region the lens having a first refractive index and an optical interface surface. A second liquid optically-transmissive material then dispensed into a second mold cavity over the optical interface surface while the first region of the lens is disposed within the second mold cavity. The second liquid optically-transmissive material in the second mold cavity is cured to form a second region of the lens having a second refractive index. An optical interface between the first region and the second region conforms to the optical interface surface.

Abstract: A lens assembly includes a tube in which optical elements such as lenses or micro-lenses are individually fabricated by dispensing a volume of curable optical polymer into the tube, forming the desired shape for the optical element using one or more plungers having heads corresponding to a desired lensing curvature, applying radiant energy to the tube with the plungers in place to cure the optical polymer, and repeating as needed until the desired number of optical elements are fabricated within the lens assembly which may then be integrated as a single piece into a mobile or wearable device.
