The horse uses its binocular vision by looking straight at an object, raising its head when it looks at a distant predator or focuses on an obstacle to jump. To use binocular vision on a closer object near the ground, such as a snake or threat to its feet, the horse drops its nose and looks downward with its neck somewhat arched.
In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and shares no field of view between them, like in some ...
This means that horses have a range of vision of more than 350°, with approximately 65° of this being binocular vision and the remaining 285° monocular vision. [74] Horses have excellent day and night vision, but they have two-color, or dichromatic vision; their color vision is somewhat like red-green color blindness in humans, where certain ...
Blinkers, also known as blinders, blinds and winkers, are a part of horse harness and tack which limits a horse's field of vision—blocking vision to the sides, the rear, or both. [1]: 56 [2] Blinkers are usually seen in horse driving and in horse racing (both harness and ridden), but rarely in horse riding. [3]: 20

The horse has a wide field of monocular vision, as well as good visual acuity. Horses have two-color, or dichromatic vision, which is somewhat like red-green color blindness in humans. [27] Because the horse's vision is closely tied to behavior, the horse's visual abilities are often taken into account when handling and training the animal.
