- 원거리 굴절률을 갖는 원거리부와, 근거리 굴절률을 갖는 근거리부가 영역을 구획하여 모두 형성된 노안용 콘택트렌즈에 있어서,
원거리 굴절률로 형성되어 주시야를 제공하는 중심영역과; 가장자리를 따라 환형태로 형성된 마감영역과; 상기 중심영역과 마감영역 사이에 형성되고 굴절력이 형성되어 시야영역을 제공하며, 일정각의 부채꼴형상으로 상부영역인 원거리부와 하부영역인 근거리부를 구획하고, 원거리부와 근거리부의 경계지역에는 일정폭으로 서로 다른 두 굴절률의 두께차이를 완만하게 연결시키는 이행부가 형성되는 광학영역;으로 구획하여 구성되되;
상기 광학영역에서 우세안(dominant eye)은 원거리부 206.5~208.5 도와 근거리부 146.5~148.5 도의 범위에서 좌우 대칭으로 굴절률을 형성하고, 열세안(non-dominant eye)은 원거리부 146.5~148.5 도와 근거리부 206.5~208.5 도 범위에서 좌우대칭으로 굴절률을 제공하고, 이행부는 3~7도의 범위에서 두께를 완만하게 연결시키고,
상기 광학영역에서 렌즈착용시 굴절률은, 우세안은 원거리부위 목표굴절률은 정시(Emmetropia)이고, 근거리부위의 목표굴절률은 -0.75 디옵터(D)로 형성하고; 열세안은 원거리부위 목표굴절률은 -0.5 디옵터(D)이고 근거리부위의 목표굴절률은 -2.25 디옵터(D)로 형성하는 것을 특징으로하는 노안용 콘택트렌즈. - 삭제
