Publication number: 20260166826Abstract: A method of producing an ophthalmic lens including depositing polymerizable mixture onto a receiving surface of a substrate that is positioned within a package, layering the polymerizable mixture in one or more passes of an additive print head over the substrate where the layers form a three-dimensional structure of the ophthalmic lens, and curing the deposited mixture by exposing it to an actinic radiation, thereby initiating polymerization and forming a solid form of the ophthalmic lens. The method further requires sealing the substrate and formed ophthalmic lens within the package in a dry, non-hydrated state, where the formed ophthalmic lens remains adhered to the receiving surface, and shipping the sealed package having the substrate and formed ophthalmic lens therein in the dry, non-hydrated state.Type: ApplicationFiled: December 11, 2025Publication date: June 18, 2026Inventors: W.

Publication number: 20260021631Abstract: Methods of forming an ophthalmic element via generating a map of data values associated with pixels included in an energy transmissibility pattern. Data values correspond with an amount of energy transmissible through the optical element at a pixel location. The data values may be converted to additive manufacturing printhead control commands. A first print pattern of polymerizable mixture is emitted as droplets from a manufacturing printhead. The first print pattern of polymerizable mixture corresponding with the map of data values associated with pixels included in an energy transmissibility pattern. At least a portion of the droplets are received on a receiving surface.Type: ApplicationFiled: August 20, 2025Publication date: January 22, 2026Inventors: W.

Publication number: 20250172722Abstract: Improved ophthalmic devices including optical sub-elements with custom design for directing images to specific portions of a patient's retina. The optical sub-elements may be used to direct images along a direction divergent from a central axis of the lens base. By redirecting images along divergent directions, ophthalmic devices according to the present invention allow users with specialized needs, such as low light conditions and/or retinal damage to utilize undamaged regions of the retina to have a higher degree of vision capability.Type: ApplicationFiled: November 29, 2024Publication date: May 29, 2025Applicant: Atheneum Optical Sciences, LLCInventors: W.
