Abstract
It is proved that the field of a gravitational lens induces no rotation in the polarization vector of electromagnetic radiation, in agreement with the previous literature, but with a different approach. The result is generalized to the case of less conventional gravitational lenses (static cosmic strings and gravitational waves).
