Abstract The present paper is a brief survey of the theoretical results relating to the gravitational focusing, or gravitational lensing effect. Patterns of obtaining solutions in the approximations of geometrical and wave optics are shown. The influence of random effects such as inhomogeneities of gravitation fields and the interstellar plasma is studied. Some astrophysical applications of the lensing effect are considered.
