A method () of manufacturing an ophthalmic lens is described. The method comprises providing a lens substrate () and providing a photocurable film (). The method comprises using a digital light projection system to photocure at least one region of the film, thereby producing at least one photocured gradient index optical element having an asymmetric refractive index profile (). The method comprises applying the film to a surface of the lens substrate ().

Methods of manufacturing an ophthalmic lens including asymmetric gradient index optical elements

A film (), an ophthalmic lens including a film (), spectacles comprising an ophthalmic lens including a film (), and a method of manufacturing a film () are described. The film () has a base refractive index and includes at least one gradient index optical element () having an asymmetric refractive index profile.

Films having asymmetric grin optical elements for application to spectacles or other ophthalmic lenses

An ophthalmic lens (), a film for use in an ophthalmic lens () and a method () of manufacturing an ophthalmic lens () are described. The lens () has an optical axis. The lens () comprises a layer () provided on a surface of a substrate (). The layer () has a base refractive index and includes at least one gradient index optical element () having an asymmetric refractive index profile. The at least one gradient index optical element () focuses light from a distant point source on the optical axis to a point that is a first distance from the optical axis ().

Ophthalmic lenses including asymmetric gradient index optical elements

A film for applying to an ophthalmic lens is described. The film, or the combination of the film and the ophthalmic lens are designed to prevent or slow the development or progression of myopia. The film has a base refractive index and includes at least one gradient index optical element. Ophthalmic lenses, such as spectacle lenses and contact lenses, that include the films are also described.

Films having grin elements for application to spectacles or other ophthalmic lenses

A contact lens comprising one or more microchannels for transport of liquid through the lens is provided. The contact lens can be made by contacting a curable composition with a microfiber that is insoluble in the curable composition; curing the curable composition to provide a polymeric lens body with the microfiber embedded therein; and contacting the polymeric lens body with a solvent to dissolve the microfiber.

Contact lenses with microchannels

Methods of manufacturing an ophthalmic lens are described. The methods include a step of providing an ophthalmic lens; and a step of providing a photocurable film. The methods use a digital light projections system to photocure at least one region of the film to produce at least one photocured gradient index refractive element. The film is applied to a surface of the lens.

Methods of manufacturing an ophthalmic lens

A contact lens having dimples on a posterior surface is described as well as cast molds and injection molding inserts for manufacturing the same. The contact lens includes a posterior surface having an optic zone, a peripheral zone, and a circumferential edge, where dimples are located in the peripheral zone, and can include at least 1000 dimples.
