Filed: 1988-06-24
Abstract: PURPOSE: To prevent the visual field of a person who uses lenses, for spectacles from being interrupted by drawing patterns on the outside surface of the lens for spectacles, and forming many see-through windows from which coloring is removed with intervals in the colored area in which the patterns are drawn. CONSTITUTION: Colored patterns 18 such as a design is applied on the outside surface 22 of a lens 16 for spectacles by a proper printing means or the like. However, many small circles 26 as see-through windows are formed with proper intervals in the colored area of the operated pattern 18. Therefore, the outside surface 22 surrounded by those small circles 26, that is, the inside parts of the small circles 26 are present in a state in which coloring constituting the pattern 18, for example, pigment or the like is removed. Thus, a person who uses the lens for spectacles or the spectacles using the lens can look outside through the lens for spectacles without interrupting the visual field.  Also, the other people can not look at the eyes of the spectacle user due to the existence of the patterns while only the patterns operated to the surface of the lens for spectacles can be recognized.
