Title:
METHOD OF MANUFACTURING EYEGLASS LENS
Document Type and Number:
Japanese Patent JP2012187703
Kind Code:
A
Abstract:

To provide a means for manufacturing eyeglass lenses with high productivity from semi-finished lenses with a functional film.

A method of manufacturing eyeglass lenses is provided which includes a step of forming an optical surface by polishing a non-optical surface 2b of a semi-finished lens 1 whose one surface is an optical surface and the other surface is a non-optical surface 2b. The semi-finished lens 1 has an acrylic coating 11a on the optical surface of a lens base material 11b, wherein the contact angle with water of the surface of the acrylic coating 11a is ≤90°. Before the polishing, a protective film 46 is stuck, through an adhesive layer of the film, to the surface of the acrylic coating 11a. Then, the polishing is performed on the non-optical surface 2b of the lens base material 11b, with the surface of the protective film 46 fixed to a block implement 37.
