Abstract
An eye lens includes an optical part, which defines a first optical surface. The first optical surface is configured as turn with a pitch extending circumferentially about a principal axis (A) of the eye lens. A transition region is formed between a beginning and an end of the turn, which with a beginning edge and an end edge merges into the turn. The beginning edge extends between the principal axis (A) and a first circumferential location and the end edge extends between the principal axis (A) and a second circumferential location. The beginning edge projected into a plane (H) perpendicular to the principal axis (A) has a non-linear course and/or the end edge projected into a plane (H) perpendicular to the principal axis (A) has a non-linear course.
