An optical imaging lens includes a first, a second, a third, a fourth, a fifth, a sixth, a seventh and an eighth lens elements from an object side to an image side in order along an optical axis. The eight lens elements are the only lens elements having refracting power in the optical imaging lens. The optical imaging lens satisfies: (T1+T2+T3)/(G23+G34)≥2.700, wherein T1 is a thickness of the first lens element along the optical axis, T2 is a thickness of the second lens element along the optical axis, T3 is a thickness of the third lens element along the optical axis, G23 is an air gap from the second lens element to the third lens element along the optical axis, and G34 is an air gap from the third lens element to the fourth lens element along the optical axis.

Embossing resins, methods of manufacturing such resins, and electrokinetic display system, which includes display cells containing such resins. The resins include a fluoropolymer in weight percentage 5%-60%, a difunctional diluent in weight percentage 0-30%, a monofunctional diluent in weight percentage 0-40%, a urethane diacrylate or functionalized nanoscale material, e.g., a functionalized urethane material, in weight percentage 5-50%, a photoinitiator in weight percentage 0.5-5%, and a surfactant in weight percentage less than 0.5%. The difunctional diluent may be Hexanediol Diacrylate, and the monofunctional diluent may be a monofunctional hydrocarbon. The resins are made by identifying a target index of refraction for a cured state thereof, and combining together, by weight percentage, the constituent components to produce the liquid state version of the embossing resin having a desired composite index of refraction.

Embodiments disclosed herein include eyewear that has one or more laminates applied to a lens body. In some embodiments, the lens body is constructed from a substantially rigid material having a curved shape. The lens body can have any desired curvature, including, for example, cylindrical, spherical or toroidal. A laminate can include a substantially flexible substrate and one or more functional layers or coatings applied to the substrate. In addition, one or more functional layers or coatings can be applied directly to the lens body. In certain embodiments, a bonding layer bonds a laminate to a convex and/or concave surface of the lens body. Examples of functional layers or coatings that can be applied to a laminate include anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.

Disclosed are high refractive index, hydrophobic, acrylic materials. These materials have both high refractive index and a high Abbe number. This combination means the materials have a low refractive index dispersion and thus are especially suitable for use as intraocular lens materials. The materials are also suitable for use in other implantable ophthalmic devices, such as keratoprostheses, corneal rings, corneal implants, and corneal inlays.

The present invention provides an optical composition from which an optical article having reduced poor appearance such as cloudiness and optical strain during lens base material production can be obtained, and when a photochromic compound is added, a photochromic cured body having excellent photochromism and mechanical strength can also be formed, and a polyrotaxane used therefor. The polyrotaxane has a composite molecular structure formed of an axle molecule and a plurality of cyclic molecules clathrating the axle molecule, satisfying at least one of (X) and (Y). (X): A side chain having a secondary or tertiary hydroxyl group is introduced into at least part of the cyclic molecule of the polyrotaxane. (Y): A side chain having a group represented by -A (A is an organic group, and contains at least one hydroxyl group) is introduced into at least part of the cyclic molecule of the polyrotaxane, and a pKa of the hydroxyl group of the compound represented by H-A is 6 or more and less than 14.

The present invention relates to an optical film exhibiting excellent optical properties such as low gloss value and reflectance, and an appropriate level of haze properties, and to an image display device including the same. The optical film comprises: a light-transmitting substrate film; an antiglare layer including a binder containing a (meth)acrylate-based crosslinked polymer, and organic fine particles of a micron (μm) scale dispersed on the binder and inorganic fine particles of a nanometer (nm) scale dispersed on the binder; and a low refractive index layer which is formed on the antiglare layer and includes a binder resin containing a (co)polymer of a photopolymerizable compound, and hollow silica particles dispersed in the binder resin, wherein the organic and inorganic fine particles exhibit a predetermined particle size distribution, refractive index difference, and content range.

Provided is, for example, a pattern-forming composition that contains a triazine ring-containing polymer having a predetermined repeating unit structure, represented by formula [4] below, a crosslinking agent, and an organic solvent.
