An ophthalmic lens may comprises a main body comprising a first surface and a second surface opposite the first surface, the main body having a diameter, a base curve, a peripheral thickness, and a center thickness, wherein, one or more of the diameter, the base curve, the peripheral thickness, or the center thickness are configured such that a dsag is less than 1.3% when comparing a first orientation of the main body with at least a portion of the first surface abutting an eye of a wearer and a second orientation of the main body with at least a portion of the second surface abutting the eye of the wearer.

Apparatuses and methods for multistage molding of contact lenses containing low oxygen permeable components or oxygen impermeable components. Components may be embedded within a contact lens by forming a device on a polymer substrate, molding a spacer onto a male mold, bonding the device to the spacer, removing the polymer substrate, and molding the remainder of the contact lens.

A device includes a contact lens, a corneal sensor that includes a circular trace of conduction paths located at or near an outer peripheral edge of the contact lens that surrounds an unobstructed area at a center region of the contact lens, and a connection wire coupled to the corneal sensor and configured to electrically couple to an external data acquisition system. Methods of fabricating the device may include providing a thin device that includes a sensor and a connection wire coupled to the sensor, transferring the sensor to a curvilinear inner surface of a contact lens, feeding the connection wire through the inner surface of the contact lens and out of an outer surface of the contact lens, and performing electrochemical polymerization of a conducting polymer material over the sensor to anchor the sensor to the inner surface of the contact lens.

A method comprises: disposing a measurement contact lens upon an eye of a user; capturing at least one image of the eye and the measurement contact lens with an image sensor while the measurement contact lens is on the eye of the user and the eye is illuminated; processing the at least one image to obtain a centration of the measurement contact lens on the cornea of the eye; processing the at least one image to obtain an angular orientation of the measurement contact lens on the cornea of the eye; and determining, based on the centration and angular orientation of the measurement contact lens on the cornea of the eye, at least one parameter of a first contact lens to be worn on the eye with display eyewear or a second contact lens to be worn on the eye without the display eyewear.

A contact lens having dimples on a posterior surface is described as well as cast molds and injection molding inserts for manufacturing the same. The contact lens includes a posterior surface having an optic zone, a peripheral zone, and a circumferential edge, where dimples are located in the peripheral zone, and can include at least 1000 dimples.

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

A system of contact lenses includes at least two contact lenses, each lens having a visual correction for a non-rotationally symmetric eye aberration. Each lens has a different level or degree of a stabilization that is characterized by a thickness differential between a thickness of a stabilization zone and a thickness of a non-stabilization zone.

A contact lens for treating myopia of an eye of a patient comprises an anterior surface; and a posterior surface having a semi-meridian defining: a central compression zone to contact the pretreatment cornea, a volume control zone peripheral to the central compression zone, a secondary compression zone to contact the pretreatment cornea, wherein the secondary compression zone is peripheral to the volume control zone, a peripheral relief zone peripheral to the secondary compression zone, a landing zone to contact the pretreatment cornea, wherein the landing zone is peripheral to the peripheral relief zone, and an edge terminus peripheral to the landing zone.

This invention comprises a combined optical wavefront aberrometer and topographer system that is used in conjunction with a contact lens that has a plurality of fiducial marks disposed on the lens. The fiducial marks are located radially inside of the undilated pupil's diameter. The optical imaging capacity of the aberrometer is used to measure and monitor any misalignments of the contact lens's position (XY decentration) and/or rotation. Image analysis algorithms are used to track the positions of the fiducial marks, and, hence, the amount of geometric misalignment of the contact lens can be calculated. The fiducial marks can comprise micro ink spots, or depressions in the surface of the contact lens (e.g., divots, dimples, pits), or other small surface features, including raised bumps, which can help to stabilize motions of the contact lens on the eye.

A lens for an eye that includes a zone with a first power profile for images received by the retina on the fovea, a zone with a second power profile for images received by the peripheral retina on the nasal side and a zone with a third power profile for images received by the peripheral retina on the temporal side. The first power profile is selected to provide clear or acceptable vision and the second and third power profiles are selected to affect the peripheral image position.
