Even when the horse has focused as best it can, its sight is only three-fifths that of a human. In other words, when looking at an object twenty feet away, the horse sees only as much detail as a person with twenty-twenty vision would if the object were thirty-five feet away.
People with good eyesight, on a clear night, can see the Pinwheel galaxy, and that's about 27 million light years away. That's the most distant thing I know of that can be seen with the naked human eye. Vision is constrained by how clear the air is, and how much light is reflected or emitted by the object being viewed.
