摘要： The present disclosure relates to a 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 one or more meridionally and azimuthally variant power distributions, wherein at least one of the meridionally and azimuthally variant power distribution is devoid of mirror symmetry, the second region located substantially away from the optical centre and configured to provide at least in part a regional conoid of partial blur 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.

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.

摘要： The present disclosure relates to use of single vision ophthalmic lenses for correction of myopia in a wearer, wherein the single vision ophthalmic lens devices are configured with a base prescription to correct the myopia of the individual and are purposefully further configured with non-refractive features, wherein the non-refractive features facilitate an increase in the retinal ganglion cell activity for the wearer, which may serve as an optical stop signal to decelerate, ameliorate, control, inhibit, or reduce, the rate of myopia progression of the wearer.
