A ophthalmic lens for inhibiting progression of myopia includes a central zone and an annular zone. The annular zone includes subsurface optical elements formed via laser-induced changes in refractive index of a material forming the annular zone. The subsurface optical elements are configured to modify distribution of light to the peripheral retina of a user so as to inhibit progression of myopia.

An apparatus, system and method including an ophthalmic lens having an optic with an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a first region having a first optical power and a second region having a second optical power. The ophthalmic lens further includes a third region having an optical power that progresses from the first optical power to the second optical power. The progression may be uniform or non-uniform. Each of the first, second and progression optical power may include a base power and an optical add power. Each of the first, second and progression regions may provide a first focus, a second focus and a plurality of third foci, respectively.

There is described a medical device for management of the axial length growth of an eye of a subject. The device comprises a central region having a first power, a transition region surrounding the central region, and a peripheral region surrounding the transition region and having a second power. The transition region has a width at most equal to 1.5 mm. The second power is chosen based on the first power to achieve a target net power, the target net power being the addition of the first power and the second power. The surface area of the central and peripheral regions is chosen as a function of the surface area of the pupil of the eye. Furthermore, the curve of power within the transition region is steep between the first power and the second power so that the transition region generates no optically usable power.

The lens includes an optic zone and a peripheral zone surrounding the optic zone. The peripheral zone has a variation in thickness configured to promote rotation of the lens.

A contact lens for use in preventing or slowing the development or progression of myopia, and methods of manufacturing and using such a lens. The optic zone of the lens comprises a central region having a curvature providing a base power. The optic zone comprises an annular region circumferentially surrounding the central region. The annular region comprises a treatment zone having a characteristic that reduces the contrast of an image of an object 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 characteristic that causes the contrast reduction varies with meridian around the annular region. A peripheral zone surrounding the annular region has a constant thickness profile in every meridian or a variation in thickness configured to promote rotation of the lens.

A contact lens for use in preventing or slowing the development or progression of myopia, and methods of manufacturing and using such a lens. The lens includes an optic zone and a peripheral zone that has a variation in thickness configured to control rotation of the lens. The optic zone comprises a central region having a base power that focuses light from distant point objects to a distal focal surface, said light forming a blur circle as it passes through a proximal focal surface. An annular region surrounding the central region, includes an add power region spanning less than 75% of the annular region, and having an add power of 0.5 D or more. Points defining centres of curvature of the add power region form a segment of an annulus. The add power region focuses light from distant point objects to form a focused arc at a proximal focal surface.

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 diffractive eye lens having a front side, a rear side and an optical main axis, wherein the front side and/or the rear side has a spherical, an aspherical, a spherical-toric or an aspherical-toric basic shape, and the front side and/or the rear side has a diffractive optical structure. The diffractive eye lens allows for color correction and simultaneously improves visual properties by reducing a halo.
