(57) Abstract: In conventional spectacles, dirt easily adheres to a site that comes into contact with skin, and dirt that has once adhered is difficult to remove. SOLUTION: A surface layer consisting of photocatalyst particles alone or a surface layer containing photocatalyst particles is provided in at least a part of the eyeglass frame or a nose pad that comes into contact with the human body, and therefore the photocatalyst particles are secreted into the frame or the like by the redox action. It is difficult for dirt, dirt, and cosmetics-derived stains to adhere, the adhered stains are decomposed and removed, and the surface becomes hydrophilic, so that the adhered stains can be easily removed. |
