This disclosure relates to an electric actuator to render optical elements movable. The electrical actuator generally has a motor, a mechanical transmission assembly having an endless screw, a support element of the endless screw, a drive mechanism, and a return mechanism. The motor is configured to drive the mechanical transmission assembly and the mechanical transmission assembly is configured to drive the drive mechanism, wherein the return mechanism exerts an axial pressure against the endless screw in such a way as to press the endless screw against the support element. The disclosure also relates to an assembly having a movable optical element and an electric actuator of the movable optical element as described above.
