  • Publication number: 20240103297
    Abstract: An ophthalmic lens comprising a power profile that incorporates a plurality of lens powers wherein some of the lens powers are designed to correct for distance refractive error of the eye and other powers are either approximately relatively positive or approximately relatively negative to the distance refractive error power or both and the ophthalmic lens is designed to provide a through focus retinal image quality curve with the peak positioned in front of the retinal image plane for all pupils of about 4 to 6 mms in diameter on a model eye with zero aberrations. The through focus retinal image quality peak being similarly positioned with respect to the pupils in said range.

  • Publication number: 20220350169
    Abstract: An ophthalmic lens comprising a base lens configured to direct light to a first image plane; and a plurality of light modulating cells. One or more of the plurality of light modulating cells refract light to a second image plane different from the first image plane and/or one or more of a plurality of light modulating cells refract light to a third image plane different from the first and second image planes, In some embodiments, at least one of the plurality of light modulating cells is configured to refract light to at least two (e.g., 2, 3, or 4) image planes, different from the first image plane.

  • Publication number: 20070296916
    Abstract: A contact lens (10) for use in controlling or retarding the progression of myopia in an eye has a central optical zone (20) approximating the normal diameter of the pupil of the eye (22) that gives clear central vision at distance for the wearer. An annular peripheral optical zone 24 that is substantially outside the diameter of the pupil is formed around the central optical zone (20) with greater refractive power than that of the central zone (22) so that oblique rays entering the eye through the peripheral optical zone (24) will be brought to focus at a focal plane that is substantially on or anterior to the peripheral region of the retina. Preferably, the rear surface (16) of the lens is shaped to conform to the cornea of the eye and the front surface (18) of the lens (10) is shaped to provide—in conjunction with the rear surface (16)—the desired optical properties of the central and peripheral optical zones.
