摘要:
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.
