Title: Manufacture of plastic lens
Inventor: KOBAYASHI TADASHI
IPC: B29K75/00
Filed: 1995-04-28
Abstract: PURPOSE: To obtain a plastic lens which is free from any optical strain or extremely few in optical strain by taking a method for polymerization wherein a direction of gravity applied to any micropart of a monomer poured into a shell is varied. CONSTITUTION: A shell 1, and a rotation axis 2 are provided, and a prepared monomer liquid is poured into a shell composed of two sheets of a glass mold and a gasket. After plugging up a pouring port not to make a monomer leak, the shell is fitted to a rotation apparatus having a rotation shaft almost horizontally so that the rotation shaft passed almost vertically near a center of a glass mold surface. After binding the shell tight not to drop owing to rotation, the rotation shaft and its support are continuously rotated for 10h at 1 revolution per min at 40 deg.C. Thereafter, the rotation is stopped, temperature is raised to 120 deg.C, and the monomer is cured. The gasket and the glass mold are taken off, and a solid lens is obtained. Thereby, striae is removed, and besides time for polymerization can be shortened.  Since the monomer is polymerized while the monomer inside the shell is prevented from moving, turbidity inside a lens can be also prevented.
