摘要： An ophthalmic lens for use in preventing or slowing the development or progression of myopia. The lens has a first optical axis. A first surface of the lens is shaped to form a first surface power map. A second surface of the lens is shaped to form a second surface power map. The first and second surface power maps together form a lens power map. One of the first surface power map, the second surface power map, and the lens power map comprises: a base region and a myopia control region. The base region has a base power which focusses light to a focal point that is on the first optical axis. The myopia control region comprises a spiral shape and focusses light to a plurality of focal points that are offset from the first optical axis. Also a method of manufacturing such an ophthalmic lens.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： A film for applying to an ophthalmic lens is described. The film, or the combination of the film and the ophthalmic lens are designed to prevent or slow the development or progression of myopia. The film has a base refractive index and includes at least one gradient index optical element. Ophthalmic lenses, such as spectacle lenses and contact lenses, that include the films are also described.

摘要： 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.

摘要： 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.

摘要： 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.
