摘要 PURPOSE:To simplify the frame processing and at the same time to avoid the come-off of a set lens, by securing a range of tension 0.3-3kg that is required to induce the martensite transformation of the wire which is used to a part of a rim. CONSTITUTION:A metallic material having a pseudo elastic effect is used as a wire 1 at a part of the rim to hold a lens 2. In this case, the tension is reduced by decreasing the section area of the wire 1, and the tensile force of the rimless frame is set at 0.3-3kg. After this, the wire 1 is attached to the frame. Then the lens 2 is mounted to the frame while the wire 1 is extended by a ribbon tape 3.
