Abstract: A bifocal spectacle lens and a method for creating a numerical representation of a bifocal spectacle lens are disclosed. The bifocal spectacle lens includes a distance portion, a near portion, and a transition section situated between the distance portion and the near portion. The distance portion is optimized in view of an optical power for distance vision and the near portion is optimized in view of an optical power for near vision. The transition section is determined such that the transition section creates a continuous transition between the distance portion and the near portion. The distance portion and the near portion are optimized independently of one another and put together with the transition section to form the numerical representation of the bifocal spectacle lens.

Abstract: Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance.

Shapes of the high power segments and the low power segments are sectors. The high power segments and the low power segments are disposed alternately along an arc direction of the progressive multifocal ophthalmic lens. Shapes of the progressive power segments are sectors. Two sides of each of the progressive power segments along the arc direction respectively connect one of the high power segments and one of the low power segments. The high power segments, the low power segments, and the progressive power segments form a progressive multifocal surface.

The lens is a passive lens. The lens can be used in an optical see-through head mounted display (HMD) apparatus to allow a user of the HMD to focus on nearby virtual objects coming from the first inside surface portion while viewing nearby external-world objects and to focus on more distant virtual objects coming from the second inside surface portion while viewing more distant external-world objects.

Abstract: Aspects of the present invention provide a lens comprising a non-rotationally symmetric aspheric optical element, surface or feature and a rotationally symmetric aspheric optical element, surface or feature. The non-rotationally symmetric aspheric optical feature can be a progressive power region. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can be in optical communication when located on different surfaces of a lens or can be collapsed to occupy a single surface of a lens. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can each contribute to the add power of a lens. Distortion (e.g., astigmatism) of a lens of the present invention can be reduced (e.g., globally and/or locally) by optically combing the non-rotationally symmetric aspheric optical feature with the rotationally symmetric aspheric optical feature.

The diffractive profile can also include a peripheral zone, surrounding the central zone, which distributes a third percentage of light toward the far focus and a fourth percentage of light toward the intermediate focus.
