A method of forming an ophthalmic contact lens using an additive manufacturing apparatus is presented herein. The method providing a first solution comprising HEMA, PEGDA, and a photoinitiator, forming a support structure on a planar print bed of the additive manufacturing apparatus by depositing a first plurality of layers of the first solution and curing the first plurality of layers, and forming an ophthalmic contact lens on the support structure by depositing a second plurality of layers of the first solution and curing the second plurality of layers. The second plurality of layers are arranged such that a disc of the ophthalmic contact lens is oriented generally perpendicular to the planar print bed of the additive manufacturing apparatus.

A method of manufacturing a lens includes: injecting a thermosetting first resin in a first mold, and curing the thermosetting first resin, to form a cover blank having cover parts; removing a part or all parts of the first mold; arranging the cover blank in a second mold; injecting a thermosetting second resin having a greater light absorptance or a greater light reflectance than the thermosetting first resin into the second mold and curing the thermosetting second resin, to form a lens blank having a light-shielding part between adjacent ones of the cover parts; taking out the lens blank from the second mold; cutting the lens blank at the light-shielding part located between the adjacent ones of the cover parts to obtain individual lenses having lateral side walls and flange parts extending outward from lower-end portions of the lateral side walls, which are both covered by the light-shielding part.

Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a lens body having a lens material and a mask having a mask material. The lens body can be secured to the mask. The mask material can include a modulus of elasticity that is greater than or equal to a modulus of elasticity of the lens material.

A spectacle lens has, starting from the object-sided front surface of the spectacle lens to the opposite rear-side of the spectacle lens, at least a) one component A including at least one functional layer F.sub.A and/or an ultrathin glass, b) one component B including at least one polymer material and, c) one component C, including at least one functional layer F and/or an ultrathin glass. A method, in particular a 3D printing method, for producing the spectacle lens is also disclosed.

Systems, articles, and methods integrate photopolymer film with eyeglass lenses. One or more hologram(s) may be recorded into/onto the photopolymer file to enable the lens to be used as a transparent holographic combiner in a wearable heads-up display employing an image source, such as a microdisplay or a scanning laser projector. The methods of integrating photopolymer film with eyeglass lenses include: positioning photopolymer film in a lens mold and casting the lends around the photopolymer film; sandwiching photopolymer film in between two portions of a lens applying photo polymer film to a concave surface of a lens and/or affixing a planar carrier (with photopolymer film thereon) to two points across a length of a concave surface of a lens.

An optical element includes a first substrate having a first surface, a resin member disposed on the first surface, and a second substrate disposed above the resin member with a joining member interposed therebetween. The resin member has a first region contacting the joining member and a second region surrounding the first region and not contacting the joining member. An inclined portion having a thickness increasing from a starting point located in the second region toward an outer circumference of the resin member, is disposed in the second region. A tangent of the first surface, orthogonal to a normal of the first surface passing through the starting point, and a straight line passing through the starting point and a point at which the inclined portion has a largest thickness, form an angle of 25° or more and 45° or less.

A lens with an embedded foil is produced, comprising the steps of providing a first mold and a second mold, providing a functional foil, positioning and attaching the functional foil on the first mold, aligning the second mold relatively to the first mold, sealing the mold cavity between the first mold and the second mold, and filling a curable monomer mixture into the mold cavity, wherein either the molds are heated before the alignment step or the molds are heated after the sealing step and the following filling step is conducted with a heated monomer, or the heating of the molds follows the filling step of the UV curable monomer, followed by a UV curing step of the heated UV curable monomer mixture within the heated mold cavity.

A casting method involves providing a precursor to a mold that includes a deformable surface overlying a chamber, shaping the deformable surface according to a surface profile by adjusting a fluid pressure within the chamber and driving one or more actuators that are configured to distort the deformable surface, and solidifying the precursor while the deformable surface is shaped according to the surface profile to form an optical element.

Methods, systems, devices, and apparatuses are described. Light output by a light source may be transformed into an annular shape (e.g., a spatial distribution of the light may be modified to have an annular shape) to cure an adhesive material having a similar annular shape. For example, a system may include a light source emitting light (e.g., ultraviolet (UV) light) having an angular distribution and a spatial distribution. An optical system may modify a shape of the spatial distribution into an annular shape, and the light having the annular shape may be focused on an adhesive material to cure the adhesive material. In some examples, the adhesive material may be positioned between an optical element and a structural component, and the focused light in the annular shape may cure the adhesive material while simultaneously avoiding one or more other optical components or structures.

A method for manufacturing a coated lens by applying at least one single electromagnetic pulse to convert a coating precursor material into at least one coating. The electromagnetic pulse is delivered to the coating precursor material applied on a surface of an uncoated or precoated optical lens substrate. The at least one single electromagnetic pulse is applied from an electromagnetic source such as a flash lamp, a halogen lamp, a directed plasma arc, a laser, a microwave generator, an induction heater, an electron beam, a stroboscope, or a mercury lamp.
