Problems solved by technology

In addition, during edging, water is sprayed to cool and remove grinding materials, however, this water may infiltrate from the folded part of the adhesive tape
[0009] According to the above situation, if the existing flat adhesive tape is pasted on the surface of the spectacle lens, there will be wrinkles on the adhesive tape, and the adhesive force of the adhesive tape to the spectacle lens will decrease.

Embodiment

[0141] Next, the present invention will be described in more detail through examples, but the present invention is not limited by these descriptions.

[0142] Specifically, as shown below, after adhering an adhesive tape to a predetermined convex surface of a spectacle lens, the spectacle lens is clamped with a pair of chucks, edged, and the degree of axial deviation of the spectacle lens is observed. In addition, the present embodiment is basically in accordance with the above-mentioned embodiments, and specific parts that are not considered to be particularly repeated are omitted.

[0143] (1) Spectacle lenses for edging:

[0144] As a plastic lens (Seiko Lucious manufactured by Seiko Epson Co., Ltd.) used for eyeglasses, a lens having powers of S=+3.50D and C=+0.50D was used.

[0145] In addition, an antifouling layer is formed on the surface of the lens, and the antifouling layer contains the above-mentioned fluorine-containing silane compound of the general formula (1) o...

Abstract

The present invention provides an adhesive tape and a method for adhering the adhesive tape. A cutout (25) extending from a periphery toward a center portion of the adhesive tape (20) is formed. The cutout (25) have a shape of approximate sector with width becoming wide from center portion to periphery of the adhesive tape (20). Thus, the adhesive tape can be adhered onto the lens surface without drape generation no matter what is the curvature of the lens surface. Thus the adhesive force of the adhesive tape (20) to the lens may not reduce even spraying water for cooling or removing grinding material in edge grinding machining.

Description

technical field [0001] The present invention relates to an adhesive tape for edging and a method of adhering the adhesive tape to a lens. Background technique [0002] In glasses stores, edging processing is performed. The so-called edging processing refers to the operation of grinding the periphery of a circular spectacle lens into a shape that fits into the frame of the spectacle frame. In this edging process, first, the machining center on the surface or back of the spectacle lens is sucked and held on the chuck of the edging machine. Alternatively, the processing center of the spectacle lens is pressed from the front and back of the lens to hold the spectacle lens, and the peripheral edge of the spectacle lens is ground with a grindstone while holding the spectacle lens by friction. [0003] Among such spectacle lenses, some spectacle lenses have an antifouling layer formed on the surface of the spectacle lens. The antifouling layer uses a fluorine-containing silane com...
