摘要: A lens for sunglasses includes a convex front surface, functionally directed toward an item to be viewed, and a concave rear surface, functionally directed toward the eye of a person who is wearing the eyeglasses. The lens further includes a photochromatic layer, proximate to the front surface, and a screening layer defining a UV filter, proximate to the rear surface and arranged between the rear surface and the photochromatic layer. The photochromatic layer is in the range of wavelengths comprised between 380 nm and 780 nm and has a transmittance comprised between 10% and 60%, in an activated state thereof, and a wavelength comprised between 80% and 95%, in a deactivated state thereof. The screening layer has a transmittance lower than 0.5% in the range of wavelengths comprised between 280 nm and 400 nm.

摘要: Optical apparatuses selectively used under scotopic and mesopic vision conditions. The optical apparatuses include a lens having a low-light suitable shape effective to focus light in the eye under scotopic and mesopic vision conditions. The low-light suitable shape is distinct from a bright-light suitable shape effective to focus light in the eye under photopic vision conditions. In some instances, the optical apparatuses include a spectral filter.

摘要: An optical element, in which Stim (ipRGC) represented by Formula 1 is from 10.0 to 68.0. In Formula 1, RID65 (λ) is a spectral irradiance of illuminant D65, τ (λ) is a spectral transmittance of the optical element, and Smel (λ) is a sensitivity function of ipRGCs obtained by converting a sensitivity function of ipRGCs described in CIE S/026E: 2018 such that a maximum sensitivity thereof is identical to a maximum sensitivity of a z bar (λ) in CIE 1931 color-matching functions.

摘要: A method of forming an ophthalmic contact lens may include the steps of preparing a first resin mixture including HEMA, PEGDA and a photoinitiator, preparing a second resin mixture including HEMA, PEGDA, a photoinitiator, and a pH sensitive dye, forming a first layer of the contact lens using an additive manufacturing apparatus by dispensing and curing the first resin mixture, and forming a second layer of the contact lens onto the first layer using the additive manufacturing apparatus by dispensing and curing the dispensed second resin mixture onto an outer surface of the first layer. A ratio of HEMA to PEGDA is higher in the second resin mixture than the first resin mixture and a volume of photoinitiator in the second resin mixture is less than the is less than a volume of photoinitiator in the second resin mixture. An ophthalmic contact lens configured to treat CVD is also provided.

摘要: Embodiments of the disclosure relate to the use of dyes that impart localized regions of reduced transmittance across specific wavelength ranges. The inclusion of transmittance-attenuating dyes into a lens provides enhanced color contrast by tuning the spectrum of visible light transmission through the lens.
