To efficiently manufacture an optical element with a target form under the pressure environment during the use of it which is different from that during the manufacture of it.
A method for working an optical member under a first atmospheric pressure to manufacture an optical element used under a second atmospheric pressure that is different from the first one includes the measurement process for measuring the surface contour of the optical member under the first atmospheric pressure, the calculation process for calculating the deformation quantity of the optical member generated by the difference in atmospheric pressure between the first and second ones, and the work process for working the optical member under the first atmospheric pressure so as to make the surface contour of it the target form under the second atmospheric pressure on the basis of the surface contour measured in the measurement process and the deformation quantity calculated in the calculation process.
