PURPOSE: A method for manufacturing bridge of spectacles is provided to increase the number of use times of mold, vividly form line of a surface contacted part and easily manufacture the bridge of the spectacles in various designs by adding a process of cutting plane parts formed on a central part of the bridge of the spectacles. CONSTITUTION: In a method for manufacturing bridge of spectacles comprising the process of molding a bridge(1) of spectacles on a central part of which a plurality of plane parts(1a) are formed, the method for manufacturing bridge of spectacles comprises the steps of changing the initial bridge of spectacles into first artifact(12) by performing first forging operation on an initial bridge(11) of spectacles in which large diameter, tapered surface and small diameter are formed step by step; changing the first artifact into second artifact(13) comprising a plurality of plane parts by cutting the plane of the first artifact using a cutter; and changing the second artifact into an overall bridge of spectacles by performing second forging operation on the second artifact.
