An eye measurement instrument includes: an optical measurement subsystem for measuring an optical characteristic of an eye; an imaging system, including: a camera, an optical system including a movable optical element, and an actuator to move the movable optical element. When the movable optical element is moved into a first position outside an optical path between the eye and the camera, then the optical system focuses a first feature of the eye at the camera, and the camera is configured to capture a first image of the eye, and when the movable element is moved in a second position in the optical path then the optical system focuses a second feature of the eye, different from the first feature, at the camera, and the camera captures a second image of the eye.
