    摘要: Provided is an ophthalmic diffractive multi-focal lens with a diffractive structure including a phase profile in which a plurality of blaze shaped zones are set in a concentric circle form, wherein: at least one of the zones serves as an adjustment zone wherein an inclination direction in the phase profile is reversed with respect to that of other zones; and a light intensity level giving a peak or focal point at a position away from three focal points in a light intensity distribution of transmitted light in an optical axis direction is kept low in comparison with a phase profile without the adjustment zone.

    摘要: A system for collecting and utilizing health data can include collecting data relative to a patient's health and aggregating the data with other sources of data to define a database. The patient data can be collected using an electronic device, such as a smart contact lens or smart contact lens container. The data within the database can be manipulated, organized, or otherwise processed to determine trends, relationships, and other characteristics of the database. The characteristics of the database can be correlated to predict a health condition of the patient, generate a healthcare recommendation, or a combination thereof.

    摘要: An intraocular lens includes a polymeric lens material formed from a polymerizable composition. The polymerizable composition includes: (a) a single aromatic acrylate monomer which is an aromatic-ring containing acrylate; (b) an alkoxyalkyl methacrylate monomer having an alkoxyalkyl group with 4 or less carbon atoms; (c) an alkyl acrylate monomer having an alkyl group with 1 to 20 carbon atoms; (d) a hydrophilic monomer; and (e) a crosslinkable monomer.

    摘要: The purpose of the present invention is to provide novel contact lens manufacturing method and contact lens capable of giving a lens inner surface shape reflecting a cornea shape of a contact lens wearer more easily than before with sufficient accuracy to reflect the cornea shape, thereby improving comfort during use. By using statistical information on a corneal surface shape obtained from a population of target eyes having a feature to be treated, a fitting for a rotationally-symmetric shape is performed based on a definitional equation using a radius of curvature (R) and a conic constant (C.C.) while a fitting for a rotationally-asymmetric shape is performed based on a definitional equation using a Zernike function. A shape of a lens rear surface (20) corresponding to the corneal surface shape specified by these definitional equations is adopted for a rear surface of a peripheral area of a contact lens (10).

    摘要: A contact lens includes a lens material and a sensor coupled to the lens material. The sensor is configured to sense a measurable characteristic used to determine an intraocular pressure of an eye to which the contact lens is applied. The sensor can include a variable capacitance sensor configured to change capacitance in response to a mechanical strain of the lens material. The intraocular pressure of the eye can then be correlated to the mechanical strain of the lens material.

    摘要: A method for manufacturing a diffractive multi-focal ophthalmic lens capable of generating at least three focal points in an optical axis direction using a diffractive structure comprising a plurality of zones in a concentric circle form. A composite profile is generated by overlapping at least two starting profiles comprising a plurality of zones in a concentric circle form, and an adjusted profile is generated in which at least one of phase and amplitude is adjusted by employing a zone of the composite profile as a subject in order to set an intensity distribution in the optical axis direction and determine optical characteristics, to manufacture the diffractive multi-focal ophthalmic lens for which the adjusted profile is provided in at least a portion of the diffractive structure.
