There are a lot of differences between horses and humans. One of the less obvious is how horses see. Because of the position and structure of their eyes, they view the world in a much different way than we do. Sometimes, this is a good thing for us-like when we get caught out on trail after dark. Sometimes this works against us-like when they see the teeny, tiny flag in the field a half mile away and are convinced it is the left toe of a monster about to attack. Their vision was key to their survival, along with their speed. Understanding Horse Eyes and Vision explains what we can deduce about how horses see.
