A set of contact lenses for use in preventing or slowing the development or progression of myopia, methods of manufacturing and using such lenses. Each lens includes an optic zone and a surrounding peripheral zone that has a varying thickness profile that is configured to control rotation of the lens. The optic zone comprises a central region having a curvature providing a base power. An annular region circumferentially surrounds the central region and comprises a treatment zone having a characteristic that reduces the contrast of an image that is formed by light passing through the central region and the treatment zone compared to an image of an object that would be formed by light passing through only the central region. The treatment zone is rotationally positioned, relative to the peripheral zone thickness profile, at a different angle about the optic axis in each lens in the set of lenses.

A contact lens and a contact lens assembly are provided. The contact lens includes a lens and a deformation unit. The lens configured to be worn in a human eye. The deformation unit is mounted to the lens and configured to deform according to a deformation voltage to make the lens deformed.

An ocular lens may include a lens body including a first surface. The first surface may include a first zone including a plurality of friction reduction structures arranged in alignment with the movement of a user's upper eyelid during blinking. The first surface may also include a second zone including a plurality of friction reduction structures arranged in alignment with the movement of a user's lower eyelid during blinking.

The present disclosure relates to contact lenses for use with eyes experiencing eye-length related disorders, like myopia with or without astigmatism. This invention relates to a contact lens for managing myopia with or without astigmatism; wherein the contact lens is configured with an optical zone defined substantially centred about its optical axis to provide a meridionally and azimuthally variant power distribution resulting, at least in part, in a foveal correction of the myopic eye and, at least in part, resulting in a conoid of partial blur at the retina of the myopic eye, serving as a directional cue or an optical stop signal; and a non-optical peripheral carrier zone about the optical zone configured with a invariant azimuthal thickness distribution, with or without rotation assisting features, to further provide temporally and spatially varying stop signals to decelerate, control, inhibit, or reduce the rate of myopia progression substantially consistent over time.

The present disclosure generally relates to contact lenses for use with eyes experiencing eye-length related disorders, like myopia. This invention relates to contact lens for managing myopia wherein the contact lens comprises of an optical zone about an optical axis and a non-optical peripheral carrier zone about the optical zone; wherein the optical zone is configured with a substantially single vision power profile providing correction for the eye, and a decentred second region configured with an astigmatic, or toric, or asymmetric power distribution, the second region located substantially away from the optical centre and configured to provide at least in part a regional conoid or interval of Sturm producing an optical stop signal for the eye; and wherein the non-optical peripheral carrier zone is configured with a thickness profile that is substantially rotationally symmetric to further provide a temporally and spatially varying stop signals to reduce myopia progression.

Methods and systems wherein laser induced refractive index changes by focused femtosecond laser pulses in optical polymeric materials or optical tissues is performed to address various types of vision correction.

Disclosed herein is a contact lens comprising a lenticular in a superior portion of the contact lens wherein the contact lens attaches to an upper eyelid of a wearer by the lenticular interacting with an upper tarsal plate of the upper eyelid of a wearer, said interaction allows the contact lens to translate upwards in downgaze and maintain rotational stability. By having rotational stability and translation, a contact lens having a progressive addition optic zone is provided.

The present disclosure relates to contact lenses for use with eyes experiencing eye-length related disorders, like myopia. This invention relates to a contact lens for managing myopia of an eye; wherein the contact lens is configured with an optical zone defined substantially centred about its optical axis to provide substantially toric or astigmatic cues for the eye; and a non-optical peripheral carrier zone about the optical zone configured with a thickness profile that is substantially rotationally symmetric to further to provide temporally and spatially varying stop signals to decelerate, ameliorate, control, inhibit, or reduce the rate of myopia progression over time.

A contact lens for shaping a cornea of an eye of a patient to treat high cylinder astigmatism may include a peripheral portion, an alignment portion, a treatment portion, a reverse portion, and a staining feature. The peripheral portion may cause migration of epithelial cells from a periphery of a cornea of the eye of the patient towards a center of the cornea of the eye of the patient. The alignment portion may align the contact lens on the cornea. The treatment portion may cause migration of the epithelial cells from the center of the cornea towards the periphery of the cornea. The reverse portion may relieve pressure caused by the migration of the epithelial cells. The staining feature may contact the cornea, thereby reshaping the cornea to treat high cylinder astigmatism. The staining feature may apply a ribbon-shaped staining pattern to the cornea across the contact lens.

Embodiments concern an intraocular implantable device operable comprising a disk-shaped body having a symmetry axis and which further comprises a light-transmissive portion and an opaque portion wherein the light-transmissive portion is decentered with respect to the symmetry axis.
