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.
Visual acuity and sensitivity to motion[edit] The visual acuity of the horse, or how well it is able to see details, is around 20/33. This is slightly worse than the usual 20/20 in humans, but much better than the visual acuity of dogs (20/50), cats (20/75), and rats (20/300).
