Abstract: A WS12-releasing contact lens is described as well as method of manufacturing the same. The WS12-releasing contact lens comprises a polymeric lens body and WS12 releasably adhered to the polymeric lens body, and releases from 0.05 μg to 0.5 μg WS12 after 1 hour in a release media or when worn by a human subject. The WS12-releasing contact lens can be comfortably worn by a symptomatic contact lens wearer and can increase the duration of comfortable lens wearing time and/or reduce lens awareness events and/or reduce contact lens dryness in a symptomatic contact lens wearer.

Abstract: Methods of manufacturing an ophthalmic lens are described. The methods include a step of providing an ophthalmic lens; and a step of providing a photocurable film. The methods use a digital light projections system to photocure at least one region of the film to produce at least one photocured gradient index refractive element. The film is applied to a surface of the lens.

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.
