An injection device has a housing (38) having a housing wall and having a first window (50) provided therein. Arranged rotatably in the housing (38) is a graduation carrier (60) on which are arranged, in helical fashion, dose values (62′) that are at least partly visible through the first window (50). A second window (54) is located in the housing (38) and is arranged displaceably in the longitudinal direction of the housing (38), a rotary motion of the graduation carrier (60) being synchronized with a longitudinal displacement of the second window (54) in order to indicate, through the first window (50) and the second window (54), the injection dose value (62′) that is presently selected. Since the selected dose value (62′) is only legible when viewed through both lenses (80,90), this militates against incorrect readings of the selected dose setting.
