<P>PROBLEM TO BE SOLVED: To provide a spectacle lens whose surface sliding property is lowered to such an extent that lens shape processing can be performed without lowering the antifouling performance of an antifouling layer, and its manufacturing method. <P>SOLUTION: In the spectacle lens on whose surface the antifouling layer is formed of two or more kinds of silane compounds, at least one or more kinds of which are fluorine-containing silane compounds, the coefficient of dynamic friction of the lens surface formed by taking each of two or more kinds of silane compounds as a single component is set so that the highest value of the coefficient of the dynamic friction may be 1.4 or more times as high as the lowest value of the coefficient of the dynamic friction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
