Abstract: Apparatus and methods are described including a corrective optical element having a thickness and/or a curvature that is different in different regions of the corrective optical element, such that the corrective optical element is configured, upon being adhered to any one of a plurality of differently-shaped optically-corrective single-vision lenses, to change a focal length of the optically-corrective single-vision lens differently in different regions of the optically-corrective single-vision lens. The corrective optical element is shapeable such that the corrective optical element can conform with a shape of any one of the plurality of differently-shaped optically-corrective single-vision lenses. Other applications are also described.

Abstract: Apparatus and methods are described including a progressive lens that is configured to provide a far-vision correction and a near-vision correction. The progressive lens includes a single-focus, far-vision corrective lens that is configured to provide only a portion of the far-vision correction, and a film coupled to the single-focus, far-vision corrective lens. The film defines a far-vision corrective portion that is configured to provide the remainder of the far-vision correction, a near-vision corrective portion that is configured to provide additive near-vision correction, and an intermediate portion in which the film transitions between the far-vision corrective portion and the near-vision corrective portion. Other applications are also described.
Abstract: Apparatus and methods are described including generating a multi-focal lens and/or a progressive lens by adhering a corrective optical film to an optically-corrective single-focal lens, such as to change a focal length of the single-focal lens differently in different regions of the single-focal lens. Other applications are also described.
