Horses have eyes on the side of their head, like most prey animals (Deer, sheep, etc). This is so they can see greater area around them to identify predators. Predators, like humans, dogs and wolves have eyes in front of their head so they can focus and catch prey animals. Eyes in front give better depth perception but less peripheral vision. Horses will often move their head up and down to try and focus on things. This is why collecting and holding a horses head tucked will often cause a horse to stumble or fall.
