ABSTRACT:
The method for making an optical lens according to the present invention is characterized in comprising: a optical lens preform fabrication step of fabricating a optical lens preform which comprises a first curved portion which serves as an optically functioning part and which is on one side, a flat surface portion which is formed on the opposite side to the first curved portion, and paired beveling surfaces which are formed on the both sides of the flat surface portion; a drawing step of drawing a optical lens preform40until the optical lens preform40has obtained a desired outer diameter; and an optical lens fabrication step of cutting thus drawn optical lens preform and accordingly fabricating an optical lens. With this making method, since there are paired beveling surfaces disposed, it is possible to suppress a drawing-induced distortion.
