In connection with the possible interpretation of observations of the double quasar 0957+561 as a manifestation of the gravitational lens effect, the problem of testing the coherence of the emission of the two sources in the optical and radio ranges and possible distortions of the interference pattern due to such coherence is discussed. The importance of observing time variations in the appearance of the sources is also noted.
