The invention discloses a tunable lens and a method for operating a tunable lens. The invention relates to a tunable lens (1) comprising a fluid volume (2), a flexible membrane (3) delimiting the fluid volume (2) on one side, and a shaped element (4) attached to the membrane (3), the shaped element (4) surrounding an optically active region of the membrane, the shaped element (4) being arranged to vary, by deflection, an optical property of the tunable lens (1), in a top view, the forming element (4) has a non-circular contour (40), the contour (40) extending within an imaginary circumcircle (10), and the amount of deflection of the forming element (4) is proportional to the lateral distance of the contour (40) from the circumcircle (10). 本申请公开了可调谐透镜和用于操作可调谐透镜的方法。可调谐透镜(1)包括流体容积部(2)、柔性膜(3)和成形元件(4)，其中膜(3)在一侧对流体容积部(2)进行限界，成形元件(4)附接至膜(3)，成形元件(4)围绕膜的光学活性区域，成形元件(4)被布置成通过偏转来改变可调谐透镜(1)的光学特性，在俯视图中，成形元件(4)具有非圆形的轮廓(40)，其中轮廓(40)在假想外接圆(10)内延伸，以及成形元件(4)的偏转量与轮廓(40)到外接圆(10)的侧向距离成比例。
