Abstract: A contact lens having more than one configuration is disclosed herein. The optical power of the contact lens may be dynamically changed through the different configurations of the contact lens. The different configurations may be actuated using a valve. Also disclosed herein is a contact lens comprising a dimension, which contact lens is configured to have the dimension change non-linearly as a function of a pressure applied to the contact lens.

Abstract: Embodiments include methods and systems forming optical structures in an ophthalmic lens for improving a patient's vision by accessing a prescription for the patient; generating a variable wavefront based on the prescription; phase wrapping the first variable wavefront, wherein phase wrapping the first variable wavefront includes collapsing the first variable wavefront to a phase-wrapped wavefront having a predetermined phase height; and generating, based on the phase-wrapped wavefront, energy output parameters for forming an optical structure in the ophthalmic lens using an energy source.

Abstract: 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.
