Abstract: A multifocal ophthalmic lens wherein a first surface of the lens is shaped to form a surface power map and a second surface of the lens is shaped to form a second surface power map. The first surface power map and the second surface power map together form a lens power map. The first surface power map, the second surface power map, or the lens power map comprises a spiral. The spiral has a variation across at least a portion of the lens. Methods of making and using such lenses are also provided.

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 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: An ophthalmic lens for myopia control. A first surface of the lens varies across the lens to form a first surface power map. A second surface of the lens varies across the lens to form a second surface power map. Each of the first and second surface power maps comprise a spiral. The spirals formed by the first and second surface power maps twist in opposing directions. Related methods are also described.
