A spectacle lens for an eye of a wearer of spectacles has a front surface and a back surface, wherein the front surface of the spectacle lens faces away from the eye and the back surface of the spectacle lens faces the eye. The spectacle lens includes an optical lens substrate made of or containing mineral glass and/or organic glass, wherein the spectacle lens has at least one first antireflection coating and at least one second antireflection coating, wherein the at least one first antireflection coating has a filter effect for blue light. Further, spectacles containing the spectacle lens are also disclosed.

An eyewear device including a frame and a lens that includes a transmission control region that can at least one of reflect light, absorb light, and convert light from the environment prior to the environmental light being incident on a user. The transmission control region may alter the melatonin suppressing effect of environmental light within a wavelength range from 450 nm to 485 nm, defined as a melatonin suppression wavelength range, passing therethrough.

Apparatus and methods for producing narrow-band radiation in the green region of the visible spectrum are described. The narrow-band radiation may be used to aid subjects experiencing photophobia. In some cases, subjects may experience a reduction in pain (e.g., migraine photophobia) when using the narrow-band radiation.

An ophthalmic contact lens configured to treat color vision deficiency is presented herein. The contact lens includes a tinted region containing either or both of a first dye that is configured to absorb at least 50% of incident light in a spectral band between 480 nanometers to 500 nanometers and a second dye that is configured to absorb at least 50% of incident light in a spectral band between 550 nanometers to 580 nanometers. A method of manufacturing such a contact lens and a process of forming an ophthalmic contact lens by an additive manufacturing process is also presented.

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.

Ophthalmic lenses and light filters containing special additives that have fluorescence emission in the near infrared region of wavelengths—in order to enhance phototherapy for the human eye when it is exposed to sunlight and artificial lighting.

A method for preparing an ophthalmic device for slowing, inhibiting or preventing myopia progression involves (a) soaking an ophthalmic device in one or more first solvent solutions to swell the ophthalmic device; (b) soaking the swelled ophthalmic device in one or more second solvents solutions comprising one or more red-light blocking compounds blocking greater than about 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nanometers (nm) to about 800 nm to de-swell the swelled ophthalmic device and entrap the one or more red-light blocking compounds in the de-swelled ophthalmic device; and (c) sterilizing the de-swelled ophthalmic device.

A method for preparing an ophthalmic device for slowing, inhibiting or preventing myopia progression involves contacting an ophthalmic device having one or more reactive functional groups with one or more red-light blocking compounds having one or more reactive functional groups complementary to the one or more reactive functional groups of the ophthalmic device in a basic solution for a time period sufficient to covalently bond at least one reactive functional group of the ophthalmic device with at least one reactive functional group of the one or more red-light blocking compounds. The one or more red-light blocking compounds block greater than about 5% to about 25% of red-light transmission through the ophthalmic device at a wavelength of from about 550 nanometers (nm) to about 800 nm.

An optical article partially transmits polarized glare in tunable colors that help a user to see surface contours, while enhancing the color and at the same time maintaining the appearance of the lens still neutral.

Embodiments comprise an eyewear having a lens, the lens having an optical filter. A transmittance spectral profile of the optical filter comprises a transmission valley having a minimum transmittance with a spectral bandwidth, wherein the minimum transmittance of the transmittance valley is positioned at a first wavelength from about 450 nm to about 475 nm; and the spectral bandwidth, equal to the full width of the transmittance valley at the minimum transmittance plus 30%, is less than or equal to about 30 nm.
