Abstract
A spectacle lens that can lower the slipperiness of a lens surface to an extent that allows an edging process by making 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 as for the dynamic friction coefficient of lens surfaces defined by each of the two or more kinds of silane compounds as a single component, the highest value of the dynamic friction coefficients 1.4 times or more of the lowest value of the dynamic friction coefficients; and a manufacturing method thereof are provided.
