Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. A thickness profile of the volume of lens material may be derived from one or more eyelid profiles such that a thickness gradient of the volume of lens material is oriented to be substantially orthogonal to a target eyelid margin shape.

An augmented reality system determines the position and orientation of an eye. The system includes an electronic contact lens that projects images onto a user's retina. The contact lens includes magnetic sensors. The magnetic sensors detect magnetic fields along one axis, or more than one axis, depending on their configuration. The sensors may be a conductive coil, a solenoid, or a tunneling magnetoresistance device. The sensors detect magnetic fields generated by magnetic sources. The magnetic sources may be collocated, or non-collocated, on a wearable device, a device in the environment, or a secondary electronic device. The sources may have different orientations such that they produce magnetic fields along different axes, and the sensors are configured to independently detect the magnetic fields. The system determines the pose of the eye using a combination of the measurements, and the position and orientation of the sensors and sources.

Operation of an electronic contact lens takes into account saccadic motion of the eye and reduced visual perception during saccades (saccadic suppression). The user's eye motion is tracked, and onset of a saccade is detected based on the eye's motion. For example, saccades may be detected when the eye's acceleration or jerk exceeds a threshold. The endpoint of the saccade is then predicted in real-time while the saccade is still occurring. This may be the temporal endpoint (i.e., when the saccade ends) and/or the positional endpoint (i.e., the eye position at the end of the saccade). Operation of the electronic contact lens is adjusted based on the predicted endpoint.

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.

Example ophthalmic lenses are described herein. The optic includes a front surface, and a rear surface that opposes the front surface. The optic also includes a concavity provided on the front surface of the optic and configured to engage with the upper eyelid of the wearer.

A reversible eye enhancement contact lens 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; the main body further comprising a first region corresponding to the scleral region of an eye; a second region corresponding to the limbal region of an eye; a third region corresponding to an iris region of an eye; wherein colorants are incorporated into the first region, the second region, the third region, or combinations thereof and configured to create a cosmetic design in the first orientation that is different than the cosmetic design in the second orientation. The cosmetic designs in the first and second orientations may differ in colorant, color, limbal design graphics, inner effect design graphics, outer effect design graphics, barrier layers, clear coat base layers, or combinations thereof. The colorants may comprise metal oxide pigments, coated metal oxide pigments, organic dyes, interference pigments, and combinations thereof.

Provided is an orthokerato lens including a central portion located on a center of a lens and configured to change a refractive index by pressurizing a cornea, a fitting portion configured to form a negative pressure between the lens and the cornea to pile epithelial cells moved from the central portion, a fixing portion configured to be in contact with an eyeball and align the lens such that the center of the lens is located at a center of the cornea, a peripheral portion configured to allow tears between the lens and the eyeball to circulate, and a circulation hole configured to penetrate the central portion.

A meniscus shaped lens module comprises one or more structures that decrease an amount of pressure or force to move one or more surfaces of the lens module and increase a separation distance of anterior and posterior surfaces of the module in order to provide an increase in optical power. A lens structure of the module comprises one or more of a pattern of a surface of a central chamber, a meniscus, a reduced diameter or a soft material in order to provide increased amounts of curvature of an outer contact lens surface with decreased amounts of pressure. The pattern can be formed in one or more of many ways, and may comprise one or more of folds, patterning, bellows or concertinaed surface of an optically transmissive material having a substantially uniform thickness such as a sheet of a membrane material.

The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens further improves upon an earlier method which utilizes and combines non-circularity and thickness differential aspects which results in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently. This further improvement of stiffness profile is achieved by optimizing and selectively addressing thickness differential both diametrically and circumferentially in a non-round lens design.
