ABSTRACT:
A method for press molding preforms to obtain optical articles in which each preform is prepared beforehand to have a diameter larger than that of an optically functional area of the optical article and edges of the preform to be press mold contact with molding surfaces of a pair of molds outside an area of each molding surface corresponding to the optically functional area of the optical article, thereby elongating the lifetime of molds.
