Abstract:
An ophthalmic lens system that includes a first lens having a first power and a first refractive index and first dispersion and a second lens, having a second power and a second refractive index and second dispersion. The first lens and the second lens are selected such that when light passes through the system, negative longitudinal chromatic aberration is produced whose amount is equal to or greater than a desired amount of negative longitudinal chromatic aberration.
Abstract:
The present disclosure is directed to lens, methods of making, designing lens and/or methods using lens in which performance may be improved by providing one or more steps in the central portion of the optical zone and one or more steps in the peripheral portion of the optic zone. In some embodiments, such lens may be useful for correcting refractive error of an eye and/or for controlling eye growth.

The present disclosure is directed to systems, methods and/or devices for monitor conditions of an end-user, conditions around and end-user. In certain embodiments, the present disclosure is directed to systems, methods and/or devices for improving eye health, for example with respect to reducing the progression of myopia and/or axial eye growth of an end-user. Certain embodiments are directed to a wearable apparatus comprising: one or more sensors and one or more actuators; the one or more sensors being arranged to collect data related to at least one condition of a user and send data for processing; the one or more actuators being arranged to receive actuating signals based at least in part on a result of the processing; wherein, the wearable apparatus is arranged to be positioned in proximity to the head of the user and upon receiving an actuating signal, the one or more actuators either trigger a variation of a property of the wearable apparatus or instruct the one or more actuators to not trigger the variation of the property of the wearable apparatus.
Abstract:
The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.
Abstract:
An ophthalmic lens comprising a base lens configured to direct light to a first image plane; and a plurality of light modulating cells. One or more of the plurality of light modulating cells refract light to a second image plane different from the first image plane and/or one or more of a plurality of light modulating cells refract light to a third image plane different from the first and second image planes. In some embodiments, at least one of the plurality of light modulating cells is configured to refract light to at least two (e.g., 2, 3, or 4) image planes, different from the first image plane.
Abstract:
An intraocular lens comprising: an optic zone; and a control zone positioned peripherally relative to the optic zone and configured to reduce, minimize, and/or eliminate negative peripheral pseudophakic dysphotopsia (PPD) and/or reduce, minimize, and/or eliminate posterior capsular opacification (PCO).

Abstract:
An ophthalmic lens system that includes a lens having a first power and a first refractive index and a diffractive optical element. The lens and the diffractive optical element are selected such that when visible light passes through the system, longer wavelengths are focused at positions closer to the lens system than shorter wavelengths.
Abstract:
The present disclosure is directed generally to a lens that provides a stop signal to a myopic eye, over a substantial portion of the spectacle lens that the viewer is using. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a micro lenslet array. The present disclosure is also directed to devices, methods and/or systems of modifying incoming light through spectacle lenses that utilizes chromatic cues to decelerate the rate of myopia progression. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a refractive optical element and/or diffractive optical element that offer conflicting or contradictory optical signals at a wavelength between 510 nm and 610 nm.
Abstract:
Contact lenses are described with a corneal remodelling effect. This corneal remodelling effect is one or both of broad-area corneal remodelling and localised remodelling. The contact lenses may also have a refractive power. The refractive power may vary across the lens and for myopia may have increased power centrally. The increased power may be provided over a lens area that has increased thickness due to localised remodelling.
