The event horizon is an imaginary boundary around a gravitational singularity where its gravitational pull exceeds the ability of any form of mass or energy, including light, to escape. Nothing is visible beyond this limit. Outside the event horizon, there is a region where light is bent because of the gravitational pull. When observing this phenomenon it seems as if the light is distorted by a lens.
Note that bending of light occures even if the gravity body is not a singularity, although it has very small influence (although noticable).
