Provided are polymer compositions made by a process comprising: (a) providing a first reactive composition containing: (i) a polymerization initiator that is capable, upon a first activation, of forming two or more free radical groups, at least one of which is further activatable by subsequent activation; (ii) one or more ethylenically unsaturated compounds; and (iii) a crosslinker; (b) subjecting the first reactive composition to a first activation step such that the first reactive composition polymerizes therein to form a crosslinked substrate network containing a covalently bound activatable free radical initiator; (c) contacting the crosslinked substrate network with a grafting composition containing one or more ethylenically unsaturated compounds, wherein the contacting is conducted under conditions such that the grafting composition penetrates into the crosslinked substrate network; and (d) activating the covalently bound activatable free radical initiator at one or more selective regions of the crosslinked substrate network such that the grafting composition polymerizes with the crosslinked substrate network at the selective regions.

Ophthalmic devices containing localized grafted networks and processes for their preparation and use

Provided are compounds that may function as functionalized polymerization initiators, for instance in the manufacture of ophthalmic lenses, and to methods of such manufacture. The compounds are of formula I: wherein R, R, R, R, R, T, p, q, and n are as defined herein.

Amide-functionalized polymerization initiators and their use in the manufacture of ophthalmic lenses

A method of measuring the thickness of an ophthalmic lens includes forming an ophthalmic lens over a convexly curved surface of a forming optic, the ophthalmic lens including a light absorptive component, and with the ophthalmic lens remaining over the convexly curved surface of the forming optic, measuring the thickness of the ophthalmic lens using information about the light absorptive component of the ophthalmic lens and an intensity reference value associated with the forming optic. The method includes passing light having a wavelength through the ophthalmic lens and the forming optic, whereupon the light absorptive component of the ophthalmic lens absorbs some of the light passing through the ophthalmic lens. The light passing through the ophthalmic lens and the forming optic, which is not absorbed by the light absorptive component of the ophthalmic lens, is used to generate an image having pixel intensity data.

Systems and methods of using absorptive imaging metrology to measure the thickness of ophthalmic lenses

This invention discloses apparatus for generating an ophthalmic lens with at least a portion of one surface free-formed from a Reactive Mixture. In some embodiments, an ophthalmic lens is formed on a substrate with an arcuate optical quality surface via a source of actinic radiation controllable to cure a definable portion of a volume of Reactive Mixture.

Apparatus for forming an ophthalmic lens

An apparatus and method for forming a contact lens includes submerging a convex optical quality surface of a forming optic in a reservoir containing Lens Reactive Mixture, projecting a first Actinic Radiation with a first wavelength through pre-selected regions of the forming optic that correspond to increased thickness in the lens to be formed for selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis; projecting a second Actinic Radiation with a different wavelength through the entire forming optic to selectively polymerize the Lens Reactive Mixture on a Voxel by Voxel basis, removing the forming optic and polymerized Lens Reactive Mixture from the reservoir and applying a Fixing Radiation to form the contact lens.

Multiple-wavelength lens forming system and method

A method of measuring the thickness of an ophthalmic lens includes providing an ophthalmic lens having a light absorptive component, and passing light having a wavelength through the ophthalmic lens whereupon the light absorptive component absorbs some of the light as the light passes through the ophthalmic lens. After the light has passed through the ophthalmic lens, the light is used to generate a digital image for the ophthalmic lens that has pixel intensity data that corresponds to the shape of the ophthalmic lens. Information about the light prior to passing through the ophthalmic lens, the light absorptive component of the ophthalmic lens, and the pixel intensity data is used to calculate a thickness profile for the ophthalmic lens.

Apparatus for formation of an ophthalmic lens precursor and lens

A system and method for assessing optical corrective needs of a patient. The system includes a computer system including a processor adapted to run at least a refractive software application thereon, an input device in communication with said processor and adapted to receive input from a user, and a displace device in communication with said processor and adapted to display information, and refractive eyewear including electrically adjustable left and right lenses selectively controllable to adjust at least a sphere power of the respective lenses and in communication with the processor. The refractive software application receives input from the input device and the eyewear controller, and selectively adjusts the sphere power of the left and right lenses, controls information displayed on said display device, and stores information regarding the sphere power of the respective left and right lenses.

System and method for determining corrective vision

A contact lens having a lens edge defining an outer periphery of the contact lens, an optic zone positioned within the lens edge designed to provide corrective vision for a patient, a Lens Center having a vertical axis and a horizontal axis passing therethrough, and first and second fiducial indicators present at first and second different locations around the lens edge. The first and second fiducial indicators each include at least one recess into or at least one projection extending outwardly from the lens edge and are different from one another.

Lens edge features for determing lens placement and alignment

This invention describes methods and apparatus for implementing a Convergence Process to Converge a Lens Design wherein a previous DMD Show may be modified for a subsequent Iteration. In preferred embodiments, an Iterative Loop may be initiated during a Convergence Process wherein one or more of various: techniques, modalities, and thickness correction methods may be implemented.
