Dynamic contact lenses fabricated with a dynamic portion that extends outward from the peripheral portion are disclosed. When worn on an eye the dynamic portion forms a tear lens for correcting vision. The dynamic portion can also be configured to provide a dynamic tear lens that changes optical power with forces applied by eyelids. The dynamic portion can be configured to assume a conforming configuration and at least one non-conforming configuration, or can be configured to assume at least two non-conforming configurations. The dynamic contact lenses can be used for correcting vision such as correcting presbyopia.

Disclosed herein are methods for quality control of contact lenses. An example method comprises receiving an input image indicative of a subject contact lens. The example method comprises outputting, based on analysis of the input image and using a first learning model, a first foreign matter metric and rejection data based on the analysis of the input image. The example method comprises outputting, using an artifact model and based on at least the rejection data, an artifact metric. The artifact model may be implemented based on one or more artifact attributes. The example method comprises outputting, using a second learning model and based at least on the first foreign matter metric and the artifact metric, a second foreign matter metric. The second learning model may be scale dependent. The second foreign matter metric is indicative of at least an accept or reject condition of the subject contact lens.

Provided is a method for forming an ophthalmic lens as well as a lens formed by such method. The method includes the curing of a reactive monomer mixture within a mold assembly under conditions to permit incorporation of functional features into selective portions of the ophthalmic lens.

Described are multifocal contact lenses that contain high energy visible (HEV) light absorbing compounds and their use for improving one or more vision attributes.

Provided are N-vinyl oxazolidinone monomers; polymers and polymeric networks made therefrom; and the use of these materials in ophthalmic devices and/or packaging solutions for ophthalmic devices, such as contact lenses. The N-vinyl oxazolidinone monomers are of formula (I): wherein R 1 , R 2 , R 3 , R 4 , and R 5 are as defined herein.

A composition for light filtering, the composition comprising: a base material comprising a HEMA-based material; a plurality of metal nanoparticles dispersed in the base material, wherein the plurality of metal nanoparticles exhibit a peak light absorption value in the range of about 500 nm to about 600 nm; an anchoring mechanism dispersed in the base material, the anchoring mechanism comprising methacryloyl-derived monomer; and a nanoparticle coating material disposed on at least a portion of the plurality of metal nanoparticles.

Described herein are soft contact lens sets and methods of designing soft contact lens sets based on incorporating different levels of spherical aberration into the lens design depending on the target spherical power. The different levels of spherical aberration are equal to or less than zero D/mm 2 , and account for clinically measured population-average ocular spherical aberration, manufacturing variations and generalized accommodative ability.

Described are multifocal contact lenses that contain high energy visible (HEV) light absorbing compounds and their use for improving one or more vision attributes.

This invention relates to comfortable ophthalmic devices and methods of producing such devices by treating a polymerized ophthalmic lens with a polymeric wetting agent, wherein the ophthalmic lens does not comprise said polymeric wetting agent prior to its polymerization.

Described herein are systems and/or methods for designing a system of contact lenses with interocular refractive disparity (i.e. anisometropia) for presbyopes. An example method may comprise a step of determining a plurality of lenses for inclusion in a system of contact lenses for treating presbyopes. Each of the plurality of lenses may be configured for an optical correction and may have a power profile associated therewith. The plurality of lenses may be grouped based on the optical correction. Each of the lenses in a particular group may have a different power profile. The example method may comprise a step of creating, based at least on the plurality of lenses and an add need, a fit guide. The fit guide may provide an interocular disparity of effective add. The interocular disparity of effective add may be determined by optimizing cyclopean performance across a range accommodative demands and light levels.
