Claims (8)
- 원용부(遠用部) 영역, 근용부(近用部) 영역, 중간부 영역을 갖고, 물체측 굴절면은 회전축 대칭인 비구면의 일부에 의해 구성되고, 안구측 굴절면은 누진 굴절면인 누진 굴절력 렌즈에 있어서,원용부 측정 기준점에서의 물체측 굴절면의 곡률 C1과 근용부 측정 기준점에서의 물체측 굴절면의 곡률 C2 사이에 C1<C2의 관계가 있는 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 1 항에 있어서,근용부 측정 기준점으로부터 외주부의 영역에서의 물체측 굴절면의 곡률을 C3라고 한 경우, C3<C2의 관계가 있는 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 1 항 또는 제 2 항에 있어서,안구측 굴절면은 안경 착용시의 광학 성능을 보정하기 위한 비구면 요소를 부가한 누진 굴절면인 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 3 항에 있어서,근용부 영역에서 광학 성능을 보정하기 위한 비구면 요소는, 원용부 영역에서 광학 성능을 보정하기 위한 비구면 요소와 다른 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 3 항에 있어서,착용시에서의 정점(頂点)간 거리, 착용시 전 경사각 및 작업 거리 중 어느 하나의 요소를 고려하여 비구면 요소를 설정한 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 1 항에 있어서,안구측 굴절면은 난시 보정 요소를 부가한 누진 굴절면인 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 1 항에 있어서,원용부 측정 기준점을 중심으로 하는 직경 5mm의 범위에서, 물체측 굴절면의 곡률 변화 ΔC1은 ΔC1≤0.25/(n-1)의 관계를 만족시키며, 여기서, n은 렌즈 기재(基材)의 굴절률인 것을 특징으로 하는 누진 굴절력 렌즈.
- 제 1 항에 있어서,근용부 측정 기준점을 중심으로 하는 직경 5mm의 범위에서, 물체측 굴절면의 곡률 변화 ΔC2는 ΔC2≤0.25/(n-1)의 관계를 만족시키며, 여기서, n은 렌즈 기재의 굴절률인 것을 특징으로 하는 누진 굴절력 렌즈.
