Title (EN) TORIC OCULAR LENS
(FR) LENTILLE OCULAIRE TORIQUE
(JA) トーリック眼用レンズ
Abstract:
(EN) The present invention realizes a toric ocular lens having an edge whereby a lens conducive to preventing cataract can be designed without reducing the degree of freedom of lens design. The toric ocular lens according to the present invention is configured so that a substantially flat part in which the edge thickness of an optical part is substantially constant is provided so as to be superposed on the major meridian of a toric surface of the optical part in a top view of the optical part.
(FR) La présente invention réalise une lentille oculaire torique ayant un bord de telle sorte qu'une lentille conduisant à la prévention de la cataracte peut être conçue sans réduire le degré de liberté de conception de lentille. La lentille oculaire torique selon la présente invention est configurée de telle sorte qu'une partie substantiellement plate dans laquelle l'épaisseur de bord d'une partie optique est substantiellement constant, et est disposée de façon à être superposée sur le méridien principal d'une surface torique de la partie optique dans une vue de dessus de la partie optique
(JA) レンズ設計の自由度を低下させることなく白内障防止に資するレンズを設計することが可能なエッジを有するトーリック眼用レンズを実現する。トーリック眼用レンズを、光学部の上面視において、光学部のエッジ厚が略一定となる略平坦部が、光学部のトーリック面の強主経線と重なるように設けられている、トーリック眼用レンズとする。
