PROBLEM TO BE SOLVED: To provide a method for manufacturing a lens and a lens manufacturing apparatus by which the lens can be prevented from coming off even if an oscillation angle is large.SOLUTION: A method for manufacturing a lens is provided for manufacturing a glass lens by grinding or polishing a glass material, and includes a machining process of making a machining object face of the lens abut on the machining face of a grinding wheel grinding or polishing the lens, oscillating the grinding wheel in relation to the lens while rotating at least one of the lens and grinding wheel. In the machining process, the number of revolutions Nof the grinding wheel is changed according to an oscillation angle &thetas; being an angle between a rotation axis of the lens and a rotation axis of the grinding wheel. |
