Fish eye, another name for convex or diverging mirror, has a reflective surface that's buldging towards the light source. As a result of this, it has wider angle of view and is called fish-eye (because the eyes of a fish have wider angle of view). Fish-eye mirror also makes the objects it reflects look distorted, smaller, and farther than the actual distance.
Convex mirrors have a variety of uses. One of them is like the one in the picture. Installed at a blind corner or junction, it can help drivers see other vehicles coming from around the corner. This one is at the end of the housing block where I live.
