STAINPROOF EYEGLASS LENS AND METHOD FOR PRODUCTION THEREOF

摘要

Provided are a spectacle lens and a manufacturing method thereof that can lower the slipperiness of its lens surface to an extent that allows an edging process without deteriorating the stain-proofing performance of the stain-proofing layer, when a stain-proofing layer is formed of two or more kinds of silane compounds including at least one or more kinds of fluorine-containing silane compounds, and of the dynamic friction coefficients of a lens surface obtained if each of the two or more kinds of silane compounds is employed as a single component, the highest value of the dynamic friction coefficients is 1.4 times or more the lowest value of the dynamic friction coefficients.
