This review surveys some recent developments concerning the effect of the cosmological constant on the bending of light by a spherical mass in Kottler (Schwarzschild-de Sitter) spacetime. Some proposals of how such an effect may be put into a setting of gravitational lensing in cosmology are also discussed. The picture that emerges from this review is that it seems fair to assert that the contribution of I > to the bending of light has by now been well established, while putting the I > light-bending terms into a cosmological context is still subject to some interpretation and requires further work and clarification.
