A tool provided that individually creates three-dimensional structural elements which are sequentially positioned into formation of a shaped object.

An ultra-small camera module with wide field of view includes (a) a wafer-level lens system for forming, on an image plane, an image of a wide field-of-view scene, wherein the wafer-level lens system includes (i) a distal planar surface positioned closest to the scene and no more than 2.5 millimeters away from the image plane in direction along optical axis of the wafer-level lens system, and (ii) a plurality of lens elements optically coupled in series along the optical axis, each of the lens elements having a curved surface, and (b) an image sensor mechanically coupled to the wafer-level lens system and including a rectangular array of photosensitive pixels, positioned at the image plane, for capturing the image, wherein cross section of the ultra-small camera module, orthogonal to the optical axis, is rectangular with side lengths no greater than 1.5 millimeters.

A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.

An optical article that includes an optical element and an anisotropic coating layer formed over at least a portion of the optical element. The anisotropic coating layer can include a first light-influencing zone comprising at least one first anisotropic material and a second light-influencing zone comprising at least one second anisotropic material. The at least one of the first light-influencing zone and the second light-influencing zone further include at least one dichroic material and/or at least one photochromic-dichroic material such that the first light-influencing zone and the second light-influencing zone exhibit a different color property, a different photochromic-dichroic reversible change, a different amount of polarization, or a combination thereof.

A composite functional polarized lens is a polarized lens in which lens substrate layers made of, for example, an allyl diglycol carbonate resin (produced by PPG Industries: CR-39), an urethane resin or other predetermined resin are integrally formed on both front and back surfaces of a polarizing film by way of insert molding, wherein a first lens substrate layer formed on the front surface of both the front and back surfaces of the polarizing film contains a light absorber which is an ultraviolet absorber, an infrared absorber, photochromic light absorber or a thermochromic light absorber as an additional component, and a second lens substrate layer formed on the back surface does not contain the light absorber.

According to the present invention, there is provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens and a connecting portion connecting the flash ring to the contact lens, wherein the thickness of the connecting portion is less than the thickness of the outer edge of the contact lens. There is also provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens, and a connecting portion connecting the flash ring to the contact lens wherein the mass of the flash ring is at least forty times greater than the mass of the contact lens, suitably at least sixty times greater than the mass of the contact lens. There is also provided a contact lens injection molding apparatus comprising first and second molding parts moveable relative to each other between a compressed and an uncompressed position, wherein in the compressed position, an outer edge of the first molding part is disposed 1 to 50 μm from an outer edge of the second molding part.

Display modules typically incorporate a transparent hard material such as glass on the outside of the module in order to better protect the display stack from scratches, dents, and other mechanical deformations. However, as displays move to novel form factors such as bendable, foldable, and reliable display modules, these transparent hard materials (e.g., glass) may not be used due to their limited flexibility. Therefore, it is desirable that replacement materials be sufficiently flexible while maintaining the desirable optical (e.g., >90% transmission and low yellow index) and mechanical properties (e.g., pencil hardness>H) that comparable glass hard materials offer.

A lens portion, a rib portion formed outside the lens portion, and a protruding portion protruding outward from a part of the rib portion are included, and the thickness of the rib portion is 1.4 times or more the thickness of an aperture end of a lens surface of the lens portion.

The invention concerns an optical lens comprising (i) a temporary coating at least partially covering a surface of the lens, said temporary coating comprising an outermost layer mechanically degradable through friction and/or contact; (ii) a removable film having opposite first side and second sides which adhere to said outermost layer through its first side, wherein—the first side of the film has a roughness Rq lower than 750 nm and the first side of the film has a surface energy lower than 38 mJ/m.sup.2.

The invention relates to a method for coating eyeglass lenses, in particular for coating the edge of eyeglass lenses by means of a needle metering device or jet metering device, wherein the eyeglass lens and the metering device are moved relative to one another and at the same time a coating material is applied to the eyeglass lens, in particular to the edge thereof, from the metering device. The control data for controlling the movement of the eyeglass lens and/or of the metering device are determined before and/or during the application process on the basis of geometric data of the metering device and geometry data of the eyeglass lens surface to be coated, said geometry data of the eyeglass lens surface to be coated being measured or being drawn from a data store.
