Specially designed: the horse's eyes

Horses are flight animals. They need their sense of sight to spot enemies as quickly as possible. We therefore sometimes have to battle our favorite's instincts, because a horse sees—and flees.

How do horses actually see?

Horses have (almost) all-round vision. They can see almost 360 degrees without having to move their heads. There is only one blind spot in front of the forehead, which can be important when riding, and another directly behind the tail, which should not be forgotten when handling horses.

The horse's pupil is elongated and oval, which gives it panoramic vision. However, the lateral position of the eyes limits three-dimensional vision. A horse only sees three-dimensionally in a frontal area of about 60 degrees, while its side vision is two-dimensional. When interested in an object, a horse will move it to the appropriate angle and viewing distance to see it clearly. So give your horse enough headroom when working so that it can see better. Show jumpers often demonstrate this clearly. Before a jump, they have to raise their head to focus sharply on the obstacle.

Light and shadow – the world of colors through the eyes of a horse

Please note that the signal color for horses is blue. Studies have shown that horses can recognize this color best. For this reason, it is recommended that barriers, trot poles, and obstacles used for training be kept in this color. Horses cannot recognize red. Instead, they see the world like a human with red-green color blindness: yellowish tones, blue, and many shades of gray. This is due to the cones in the retina. Humans have three different types of cones for the colors red, blue, and green. Horses only have blue and green cones.

When horses have to adjust their eyes from light to dark, it takes them a while. We humans are definitely faster at this. This explains certain behaviors of our beloved animals. From the pasture to a dark stable? Horses become insecure. Climbing into a dimly lit horse trailer when the sun is at its highest, or voluntarily walking into a dark treatment room? These are real exercises in trust for a horse.

Seeing details is not that important for horses. As flight animals, they only need to be able to perceive the slightest movements quickly so that they can get away when things get serious. Unfortunately, this means that what was supposed to be a leisurely ride can suddenly become dangerous for our four-legged friend. Things are shaking here, twitching there, enemies are lurking everywhere. The same thing can happen to us in the riding arena. Horses sometimes see ghosts peeking out from behind the fences, unidentifiable objects in the stands, or monsters running from A to B.

Eye care and diseases

Your horse does not require much eye care. On the contrary, the eye is sensitive and should not be constantly wiped. You can remove minor crusts from the corner of the eye with a soft, clean, slightly damp cloth. Always wipe from the eye towards the inner corner of the eye. But that's all you need to do. In summer, a fly veil can help protect the eye from annoying insects.

Reddened conjunctiva, increased tearing, swollen eyelids, and cloudiness are always signs that something is wrong. The eye is a very important sensory organ for your horse. Therefore, be very attentive to changes, but do not experiment. As soon as you notice anything unusual about your horse's eyes, take the animal to your veterinarian.
