Abstract:
A method of manufacturing an ultraviolet resistant object, wherein said object has at least a portion made of a polymer material, and is provided with an ultraviolet shielding film made of a substance having in itself an ultraviolet shielding property and covering at least a portion of a surface of said portion made of the polymer material, comprising the steps of:irradiating the surface of the portion made of the polymer material to be covered with said ultraviolet shielding film with ions with an ion emitting energy in a range from 0.05 keV to 2 keV to attain the total irradiation rate in a range from 1.times.10.sup.13 ions/cm.sup.2 to 5.times.10.sup.17 ions/cm.sup.2 ; andforming the ultraviolet shielding film by vapor deposition over the surface of the portion made of said polymer material and irradiated with the ions after said ion irradiation.
