摘要：
An arrangement comprising an optical element and an indication member for a drug delivery device is provided. The indication member comprises a plurality of indicia. The optical element comprises an imaging section and a light-transmissive non-imaging section, wherein the indication member is movable with respect to the optical element such that the indicia can be successively moved into a display position relative to the optical element. The imaging section is configured such that, when a first indicium is arranged in the display position, the first indicium is imaged by the imaging section into an imaging solid angle. The non-imaging section is configured such that light defining a second indicium is deflected by the non-imaging section such that the second indicium cannot be identified by a user in the imaging solid angle on a viewing side of the optical element.
