Apparatus and methods are described including a vacuum-plasma-jig () that receives an object () during application of a vacuum plasma-treatment to a first surface () of the object). A receptacle () and base () of the vacuum-plasma-jig () are shaped such that when the receptacle () receives a portion of a second surface () of the object (), there is a hollow space () proximate to the portion of the second surface () of the object (). The vacuum-plasma-jig () defines a channel () therethrough, a first end () of the channel () opening to an exterior of the vacuum-plasma-jig () and a second end () of the channel () opening to the hollow space (), a ratio of a length of the channel in mm to a mean cross-sectional area of the channel in square mm being greater than 100:1. Other applications are also described.

Apparatus and methods for applying vacuum-plasma treatment

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.

Progressive lens and manufacture thereof

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.

Optical element for converting a single-vision lens to a progressive lens

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.

Progressive lens and method of manufacture thereof

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.

Adhesive optical film to convert an eyeglass lens to a progressive lens

Apparatus and methods are described, including a corrective optical film for converting a corrective single-focal lens to a multi-focal lens and/or a progressive lens. A thickness and/or a curvature of the corrective optical film is different in different regions of the corrective optical film, such that the corrective optical film is configured, upon being adhered to the single-focal lens, to change a focal length of the single-focal lens differently in different regions of the single-focal lens. Other applications are also described.
