Abstract: A graded-index optical element may include a nanovoided material including a first surface and a second surface opposite the first surface. The nanovoided material may be transparent between the first surface and the second surface. Additionally, the nanovoided material may have a predefined change in effective refractive index in at least one axis due to a change in at least one of nanovoid size or nanovoid distribution along the at least one axis. Various other elements, devices, systems, materials, and methods are also disclosed.

Abstract: The invention is related to a class of hydrophilic poly(meth)acrylamide-based copolymers each comprising dangling (i.e., pendant) reactive chains each terminated with a carboxyl group groups and at least 50% by mole of (meth)acrylamide repeating units relative to all repeating units of the hydrophilic poly(meth)acrylamide-based copolymer. The hydrophilic copolymers have a relatively high affinity to a base coating of a polyanionic polymer on a medical device or contact lens and are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating. They can find particular use in producing water-soluble highly-branched hydrophilic polymeric material and in producing water gradient contact lenses.

Abstract: Methods and apparatus for additive manufacture of an article corresponding with an energy transmissibility image. The article may include a contact lens or intraocular lens. The improvements are directed to repeated application of a monomer according to a pattern corresponding with the energy transmissibility image, such as grayscale image. The method may include intermittent pinning of deposited polymerizable mixture, partial cure, and final cure of the deposited polymerizable mixture. A pattern of multiple defined areas may be manufactured, with each area representing an amount of energy transmissibility associated with that area.

Abstract: The present invention proposes an optical device according to claim 1. The optical device comprises a glazing with a top outer surface and a bottom outer surface extending between a first lateral end face and a second lateral end face. The glazing comprises at least one outer layer made of glass or of an optically clear polymer material. The glazing comprises a photoluminescent structure having one or more photoluminescent domains. The optical device comprises a light source for injecting excitation light into said glazing, said excitation light being suitable to excite the one or more photoluminescent domains to induce photoluminescence of the one or more photoluminescent domains. The light source is optically coupled to the glazing to inject light such that the light injected at the first lateral end face of the glazing so that the light is guided to propagate through the glazing from the first lateral end face to the second lateral end face, the glazing forming a waveguide between the top surface and the bottom surface by total internal reflection of the light at the top outer surface and the bottom outer surface, to induce photoluminescence of the one or more photoluminescent domains.
