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.[課題] 實現一種複曲面眼用透鏡，不使透鏡設計的自由度降低，而具有能夠設計有利於白內障防止的透鏡的邊緣。 [解決手段] 一種複曲面眼用透鏡，將複曲面眼用透鏡在光學部的俯視中，光學部的邊緣厚成為略一定的略平坦部，以與前述光學部的複曲面的強主經線重疊的方式設置。
