FAQs

How good is a horse's night vision? ›

Thanks to the larger numbers of rods and the tapetum lucidum, your horse has superior night vision. Galloping at full speed through the woods and pastures is no problem for equines. In fact, they see nearly as well in the dark as they do during the day.

Horses eyes are located on the side of their head, so they have a wide range of vision. They can see almost 360 degrees and have blind spots only immediately in front and immediately behind their bodies.

Equine vision is different

Human eyes adjust from brightness to dark in about 25 minutes. Your horse's eyes require 45 minutes—almost twice as long! So when you lead a horse from a sunny pasture to a dim barn, he can't see inside the barn like you can.

The veterinarian will then observe visual behavior from afar to pick up clues about how the horse is seeing and perceiving its surroundings, both in well-lit and dimly lit conditions. A neuro-ophthalmic examination tests responses to visual stimuli, reflexes to light and touch, and pupil size and movement.

Horses can identify some colors; they see yellow and blue the best, but cannot recognize red. One study showed that horses could easily tell blue, yellow and green from gray, but not red. Horses also have a difficulty separating red from green, similar to humans who experience red/green color blindness.

Horses have excellent memories and can remember certain people after long periods. A recent study completed in 2021 proved horses could recognize and understand human facial expressions and emotional responses. Extensive research has shown horses can maintain memories of humans when they have positive interactions.

Overall, the bond between horses and humans is complex and multifaceted. While horses may not necessarily "like" humans in the same way that humans like other humans, they are capable of forming close bonds with their owners and responding positively to human interaction.

Because of the placement of the eyes, horses have blind spots in their vision, which are important to understand and be aware of. They can't see directly in front of them – closer than 4 feet – or behind them, if the object is narrower than their body.

What does it mean when a horse stares at you? Your horse may gaze at you while relaxed to connect with you or to see if you've brought tasty treats. On the other hand, if your horse is staring at you with high alert signs like a raised head and flared nostrils, she might be spooked by you or something you're wearing.

Does the horse see his rider? Horses are the classic far-sighted beings, although they are considered to have poor sight. It might seem that due to the very wide visual field, they should see the person sitting on their back, however it's not the case, because the rider is in their blind spot.

How do I know if my horse is night blind? ›

The clinical signs can be subtle and include apprehension, confusion, and even injury in dim light conditions. Affected horses may be difficult to train. Affected animals occasionally display a bilateral dorsomedial strabismus (abnormal rotation of the eyes) and nystagmus (involuntary movements of the eyes).

Answer: Yes, but they cannot see in absolute pitch darkness…

Horses have excellent night vision. Horse eyes are large, they have a large pupil, and this allows ample amount of light to enter even in dark situations. On a night lit by a partial moon or stars, horses can see just as well as people can in full daylight.

Monthly Veterinary Costs

Some months you won't have to pay for any veterinary care at all! Routine equine veterinary costs—which should include vaccination, dental exams, deworming, and wellness exams—might add up to around $600 per year. So for the sake of budgeting, set aside about $50 per month for vet bills.

Generally, the vet check is paid for and arranged by the buyer. As the buyer you never want to have the seller's veterinarian do the vet check, rather you should hire your own vet or an independent vet so that if there is a problem down the road their will be no question of conflict of interest.

The eyes tell us a great deal about a horse's emotional state. A nervous horse in a new environment may have extremely expressive eyes. A tired horse may have limited eye movement and a dull, vacant look. A horse's eye is the largest of any land mammal and vision is believed to be the horse's primary sense.

Some report you should use soft eye contact when dealing with horses, meaning you can look at the horse but also keep a wide field of view. Other trainers indicate hard contact is preferred to establish your dominance over the herd.

“The first thing you learn is that horses are polyphasic opportunistic sleepers,” Greening said. “They'll sleep at different points during the day. The majority will occur during nighttime, but you need to take in how much they're doing during the day to understand how much they're doing at night.”
