This invention relates to a manufacturing process for di-, tri-, multiple-focus contact lenses. After a protecting film is attached to one part of the spherical surface contact lens, the unprotected part of this lens is ground to give a proper multification lens, and then the protecting film is removed. These steps are repeated more than once. This process is much simpler than former processes, so the manufacturing of proper contact lenese for individuals is simplified.
