  • Patent number: 11092823
    Abstract: Methods for ophthalmic lens design incorporating a visual acuity profile are disclosed. The methods include applying rules and functions to visual acuity profile data and an ophthalmic prescription to generate ophthalmic lens parameters for a subject. The visual acuity profile data includes a maximum visual acuity for the subject. The visual acuity profile data may also include a focus tolerance or tolerable blur. Tolerable blur may be measured by an ophthalmic professional or extrapolated. The visual acuity profile data may also include eye physical data such as pupil diameter and eye size, accommodation, retinal photoreceptor cell packing information and neural processing information. The visual acuity profile data may also include personal biographic and/or medical information for the subject.

  • Patent number: 10698231
    Abstract: Methods for lens configuration are disclosed. A method includes erasing a lens by heating the lens to a defined erasure temperature and writing a refractive index spatial distribution in the lens using an exposure pattern of directed ultraviolet (UV) light. The lens may be used as an ophthalmic lens or a lens used in industry. The lens comprises a rewriteable material, including, for example, liquid crystals. The lens may be erased using heat of a defined temperature. The lens may be rewritten by applying other exposure patterns to the lens using UV light.

  • Patent number: 10086575
    Abstract: Systems and methods for smoothing a lens are disclosed herein. A monomer used to make or augment the lens according to an additive method is deposited on the lens surface to be smoothed. A film or membrane with certain elastic properties is pressed against the layered (stepped) surface, with the monomer in between the lens and the membrane. The pressure of the membrane spreads the monomer over the surface of the lens, filling the spaces between the layered (stepped) surface and the membrane. A curing agent is applied to transition the monomer into a polymer coating matching the curve of the membrane. The membrane is removed, leaving a clean, smooth lens surface.

  • Patent number: 10018854
    Abstract: There is disclosed a method for recommending ophthalmic lens parameters. The method includes receiving user data from a plurality of lens wearers, receiving lens configuration information, and receiving satisfaction information for a plurality of lens wearers. The user data and satisfaction information are analyzed to identify and/or determine lens features based on correlations in the user data and the satisfaction information, including repeating the analyzing when additional user data and additional satisfaction information is received and/or on a regular basis. When new wearer information including a lens prescription for a new wearer and user data for the new wearer is received, lens parameters are produced for the new wearer including evaluating lens manufacturing characteristics based on the analyzing in correlation with the new wearer information.

  • Patent number: 9952448
    Abstract: A method that adds material selectively to a lens substrate and is used to produce a customized eyewear lens with optical power that is discernibly different from the optical power of the lens substrate. The method involves obtaining the lens substrate, calculating and generating an added material design to convert the lens substrate's optical power to a desired optical power for the customized eyewear lens, contacting the lens substrate with a bulk source of flowable radiation-polymerizable material, and irradiating the material with radiation that is controlled for wavelength range, energy and spatial distribution to polymerize the radiation-polymerizable material only in a selected area according to the added material design. The method does not require the use of external shaping structures to form the customized lens on the lens substrate, and the added material is integrally bonded to the substrate.

  • Patent number: 9933632
    Abstract: An additive processing method is used to produce a customized eyewear lens by selectively building layers of radiation-polymerized material onto a lens substrate that has optical power properties discernibly different from the optical properties of the customized eyewear lens. The method involves obtaining the lens substrate, calculating the modifications needed to convert the lens substrate's properties to the desired set of properties of the customized lens, generating an additive layer design to achieve the calculated modifications, and identifying at least one control point for confirmation or revision of the additive layer design. The method further involves applying liquid layers of radiation-polymerizable material to the lens substrate and irradiating the liquid layers in selected areas with controlled radiation such that the material is only polymerized and the additive layer is only formed in the select areas irradiated, according to the additive layer design.
