Abstract: A contact lens (301) and methods of manufacturing such a lens (301) are described. The lens (301) includes an optic zone (302). The optic zone (302) comprises a central region (305), the central region (305) having a first optical axis, a centre of curvature that is on the first optical axis, and a diameter that is less than 2.0 mm. The optic zone (302) comprises an annular region (303). The annular region (303) comprises a plurality of concentric treatment zones (303a, 303b), wherein each treatment zone (303a, 303b) has a radial sagittal power profile that increases with increasing radial distance from the optical axis.

Abstract: A contact lens for use in preventing or slowing the development or progression of myopia, and methods relating thereto, are described. The lens includes an optic zone comprising a central region having a first optical axis, and a curvature providing a base power, and centred on a centre of curvature that is on the first optical axis. The optic zone comprises an annular region, wherein the annular region surrounds the central region. The annular region comprises at least one maximum add power meridian having a curvature providing a maximum add power, and centred on a centre of curvature that is a first distance from the first optical axis. The annular region comprises at least one intermediate add power meridian, having a curvature providing an intermediate add power of between zero dioptres of add power and the maximum add power, and centred on a centre of curvature that is a different distance from the optical axis than the first distance.

Abstract: A multifocal ophthalmic lens has a surface that varies across at least a portion of the lens to form a surface power map. The surface power map comprises a spiral, with a power that varies substantially periodically both radially outwards from and angularly about an optical axis of the lens. A period of the radial variation is greater than 100 microns and a period of the angular variation is greater than 6 degrees. Methods of making and using the multifocal ophthalmic lens are also described.

Abstract: A contact lens (201) and methods of manufacturing such a lens are described. The lens (201) includes an optic zone (202). The optic zone (202) comprises a central region (205), the central region (205) having a first optical axis (219), a base radial curvature power, a base radial sagittal power, and a centre of curvature that is on the first optical axis (219). The optic zone (202) comprises an annular region (203), wherein at a point halfway across the width of the annular region (203) the annular region (203) has a radial curvature power of X, wherein X is greater than the base radial curvature power. The annular region (203) has an off-axis centre of curvature that is a first distance from the optical axis (219) such that, at a point halfway across its width, the annular region (203) has a sagittal power of Y, wherein Y is greater than the base radial sagittal power, and wherein Y is less than X.

Abstract: A contact lens (101), the lens (101) including an optic zone (102). The optic zone (102) comprises a central region (105), the central region (105) having a centre of curvature that is on an optical axis (119). The optic zone (102) comprises a first annular region (103). The first annular region (103) has an off-axis centre of curvature that is a first distance from the optical axis (119). The first annular region (103) has a sagittal power profile that increases with increasing radial distance from the optical axis (119) with a gradient of between 1.0 D/mm and 20.0 D/mm. At a point halfway across the width of the first annular region (103), the sagittal power matches the average radial sagittal power of the central region (105).

Abstract: An ophthalmic lens (112′, 200) for use in preventing or slowing the development or progression of myopia comprises an optic zone (202) for focusing light from distant point objects to a focal surface. The optic zone comprises a diffractive lens (206) for manipulating the longitudinal chromatic aberration properties of the light proximate the focal surface.

Abstract: A contact lens (2001) and methods of manufacturing such a lens (2001) are described. The contact lens (2001) comprises an optic zone (202). The optic zone (202) comprises a central portion having a centre of curvature that is on an optical axis (219), and a first annular portion (203) extending radially outwards from the central portion (205). The first annular portion (203) provides a curvature add power. One of an anterior surface and a posterior surface of the first annular portion (203) has a centre of curvature that is on the optical axis (219). The other of the anterior surface and the posterior surface of the first annular portion (203) has a centre of curvature that is separated by a first distance from the optical axis (219).
