A wide converter lens can broaden the camera's angle of view underwater, which is narrower than on land because of refraction at the boundary between air (in the lens) and water. This comes in handy when the camera's standard lens by itself requires you to move back to fit an interesting underwater formation in a composition, but the water is too murky for good visibility at that distance. If you attach a wide converter lens, you can get closer to the formation so that the water quality is no longer a limiting factor.
