Horsey Friday Fun Facts - The Eyes Have It
The horse is considered to have the largest eyes of any land animal, except for the ostrich. Their eyes are set on the side of the head and have binocular vision. What does that exactly mean?
Horses are prey animals. Prey animals eyes are set on the sides of their heads so they have a bigger picture of the area. This allows them to see two different pictures: one with each eye. Their field of vision is wide, with two blind spots. This is so that potential predators can be sighted while grazing.
There may be a time a horse will be fine going in one direction, but spook going the opposite way. That is because each eye sees a different picture. What you train a horse to do on one side must be taught also on the opposite side.
The blind spots are directly in front of it's muzzle (this is why you must keep your hand straight when feeding a treat to the horse, or it may accidentally grab your fingers) and directly behind near its tail.
Horses must move their heads and necks in order to adjust their sight. A horse will raise its head to see far away (such as when it is approaching a jump). It will lower its head and bring in its nose to see close in front (for example when walking over a log).
The next time you approach a horse from the side, remember he only sees you with that one eye.
