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).

Black Hole Ringdown Seen in Photon Polarization Swings
Polarization angle swings in photons near a Kerr black hole during ringdown lock in time to quasi-normal modes with amplitudes up to about 10 degrees.
