CN105611896B 具有矫正散光地屈光的表面型廓和径向上阶梯状的表面结构的眼睛晶状体 有权

具有矫正散光地屈光的表面型廓和径向上阶梯状的表面结构的眼睛晶状体
Abstract:
本发明涉及一种具有光学件(2)的眼睛晶状体(1)，其沿眼睛晶状体(1)的光学主轴线(A)的方向观察、具有第一光学侧面(4)和对置的第二光学侧面(5)，并且在两个侧面(4,5)的至少一个上构成矫正散光地屈光的表面型廓(7)，其中，眼睛晶状体(1)除矫正散光地屈光的表面型廓(7)外还具有在光学件(2)的径向上阶梯式的表面结构(8)，并且阶梯式的表面结构(8)在至少一个侧面(4,5)上构成。
Abstract(English):

An eye lens including an optical part, which has a first optical side and an opposite second optical side with respect to a direction of an optical principal axis (A) of the eye lens, wherein a toric refractive surface profile is formed on at least one of the two sides, wherein the eye lens has a surface structure that is stepped in a radial direction of the optical part in addition to the toric refractive surface profile, and the stepped surface structure is formed on at least one side.
