An eye projection device is provide comprising an eye projection system configured for projecting a light beam to propagate along a propagation path to an eye. The eye projection system comprises: an optical assembly defining a general optical path of light in said optical assembly, the optical assembly comprising a deflector arrangement comprising one or more adjustable optical deflectors arranged along said general optical path and configured to define an adjustable propagation path of the light beam from the optical assembly to the eye; wherein said one or more optical deflectors are configured with at least three adjustable deflection parameters affecting deflection of said propagation path to provide at least three degrees of freedom in adjusting the propagation path of said light beam towards said eye; wherein two of said at least three degrees of freedom are associated with two angular orientations of the propagation path to the eye for compensating over angular changes in a gaze direction of the eye, and at least one of said at least three degrees of freedom are associated with a lateral deflection of the propagation path for compensating over variations in a relative lateral position of said projection system relative to the eye.
