Claims (12)
- 1.少くともその1面が遠距離視域(FT)から累進帯を経由して読書視域(N T)への屈折能の増進に寄与し、また前記面または複数の面の断面曲線(水平断 面)の曲率(rh)半径が屈折能の増進に寄与し、主子午線からの距離の関数と しての水平面(y=定数)に遠距離視域における主子午線域の前面において減少 、読書視域で増進、遠距離視域の後面で増進、読書視域で減少させ、さらに曲率 (Δrh=rh(x,y)−rh(0,x)変化の過程が、主子午線の増進に従 つて逆になる累進パワー眼鏡レンズにおいて、 −前記主子午線からの距離(X)の増進に従つて水平断面(y=定数)の前記曲 率(Δrh)の変化の過程が2関数F1(x,y)とF2の次の重ね合わせによ り生ずる:Δrh=F(x,y)=F1(x,y)十F2(x,y)−第1関数 F1(x,y)に従って、曲率半径は前面において最初に増進するか、あるいは 後面で減少し、それによって前記曲率半径の変化が、前記主子午線から14乃至 26mmの距離で逆になる; −第2関数F2(x,y)に従って、曲率半径は前面において最初に減少するか 、あるいは後面において増進し、それによって前記曲率半径の変化が、前記主子 午線から14乃至26mmの距離で逆になる: −前記両関数の振幅の絶対値は、少くとも前記累進帯において前記主子午線に沿 って逆に変化する;−少くとも遠距離視域における前記主子午線の左および右の 方向に当る1つの帯に対し、次掲が適用できる;δF2/δX(x=xo,y= yo)>δF1/δX(x=xo,y=yo)(それによって、δF1/δXは 前記関数F1のXからの最初の微分である)、 ことを特徴とする累進パワー眼鏡レンズ。
- 2.前記第2関数の前記振幅は、前記遠距離視域で最大で、前記近距離視点ゼロ であることを特徴とする請求項1による累進パワー眼鏡レンズ。
- 3.前記第1関数の前記振幅は最初、眼鏡レンズの下縁から増進して、前記読書 視域(NT)の上部境界線域で最大になり、その後、減少して前記遠距離視域で 値が>0となることを特徴とする請求項1または2による累進パワー眼鏡レンズ 。
- 4.前記遠距離視域の上部域における水平断面の曲率(rh)半径は、前記主子 午線からおおよそ10mm乃至25mmの距離(X)の間で事実上一定であるこ とを特徴とする請求項1乃至3いずれか1項による累進パワー眼鏡レンズ。
- 5.前記第1および第2関数の最大振幅の絶対値の関係は10:1以上であるこ とを特徴とする請求項1乃至4いずれか1項による累進パワー眼鏡レンズ。
- 6.前記第1および第2関数の前記最大振幅の前記絶対値の前記関係は、15: 1乃至25:1の間にあることを特徴とする請求項5による累進パワー眼鏡レン ズ。
- 7.前記水平断面のどこにも近定数曲率半径を有しないことを特徴とする請求項 1乃至6のいずれか1項による累進パワー眼鏡レンズ。
- 8.前記累進帯における前記水平断面の前記曲率半径は、前記主子午線からの距 離(X)が増大するに従い前記主子午線において子午線よりも最初は小さくなり 、その後大きくなるかあるいは、前記子午線において子午線とほぼ同一の大きさ になることを特徴とする請求項1乃至7のいずれか1項による累進パワー眼鏡レ ンズ。
- 9.前記第1関数に従って前記曲率半径の変化が逆になる前記主子午線の点から の距離が前記眼鏡用レンズの下縁の方向に減少することを特徴とする請求項1乃 至8いずれか1項による累進パワー眼鏡レンズ。
- 10.前記眼鏡レンズには構造的円形域がないことを特徴とする請求項1乃至9 いずれか1項による眼鏡用レンズ。
- 11.屈折能の増進に寄与する前記面または複数面の前記主子午線は平面である ことを特徴とする請求項1乃至10いずれか1項による眼鏡用レンズ。
- 12.前記主子午線上の表面非点収差は前記遠距離視域と前記読書視域において おおよそOdptであり、前記累進帯においての値が0.5dptを超えないこ とを特徴とする請求項1乃至11いずれか1項による眼鏡用レンズ。
