How Horses See the World 🐴

[@Vision-Vibes]

What other animals should I cover in this series??

[@glory2cybertron]

Mantis shrimp

[@gailfagan7579]

I own horses and have understood that their eyes are "upside down" in that they can see the horizon very very clearly but use their whiskers and sense of smell to identify the grass they cannot see but are eating 16 hours a day with their heads down. As PREY animals that makes sense and I'm familiar with that precise distance vision as mu horses see stuff I cannot identity immediately. When my horses head goes up and his ears are focused into the distance, I pay close attention! Their eyes don't look like ours or reptiles either. We are predators as a species, they are prey as a species. It's really amazing to have develop a bond of trust and friendship with these polar opposites. Maybe a deeper dig would be in order? This is a topic worthy of more specific and amazing detail. ❤

[@aubs2cool4uuuu]

parrots, wolves, raccoons, or foxes next please!😁

[@Vision-Vibes]

@aubs2cool4uuuu I'll look into those!

[@Vision-Vibes]

I have a video out about how mantis shrimp see!

[@Voice_of_reason13th]

Along with bad depth perception! Horses have trouble seeing how deep something is. It's why crossing simple puddles or holes can scare them so much, as those things can look more like bottomless pits to a horse. And to a prey animal that relies so much on their legs, they can't afford to hurt or break one

[@aubs2cool4uuuu]

interesting! thanks for the information :)

[@Vision-Vibes]

You're welcome! 😁

[@bettykiralyi2124]

I beg to differ, my horses spot wild animals in the bush from far away long before I see them.

[@animangle]

i agree, my horse is always the one to notice animals and people before i do.

[@The_Therian_Adventures]

Same here, but it might be their ears they have excellent hearing

[@DustyHoney]

@@The_Therian_Adventures I used to ride at a ranch that had a family of jackrabbits that hung out around the arena, and the horse could sense the rabbits hiding in the bushes. Their sense of smell is also helpful for figuring out what’s going on.

[@animangle]

@@The_Therian_Adventures i agree but mine also notices things that i would consider to be purely visual. for example noticing that a side of the dressage court got blown onto it's side even though we're five hundred feet away (probably, i'm bad at estimating distance)

[@sandythewonderpony]

[@tropicalcitruscandle713]

Never let a horse poke their head out of the float like that. You are asking for an injury!

Always trust your horse- he can Smell & Hear things you cannot see

[@Vision-Vibes]

True, those senses are very strong!

[@herbert993]

Especially plastic bags in the bushes flapping in the wind

[@dave23024]

They also look at our eyes. Wanna freak a horse out? Put on some sunglasses and walk up to one.

[@HBudianu]

They can't see what's behind them, that's why you get kicked if you spook them from behind.

[@LordSandwichII]

Was kind of hoping for a horse vision simulation...

[@Vision-Vibes]

I want to make a follow-up video to this diving into their specific eye anatomy more, and I'll see if I can create a horse vision simulation for that too!

[@davidgipson7140]

Once my brother in law saved up his Marlboro points and got a telescope. We were on my dad's cattle ranch. He asked me to help him setup his telescope so later that evening he and my sister could look through it. I said where should I point it he said wherever you want. I pointed it way over the pasture towards the neighbors woods. They were 3 to 5 miles down the road. I looked through it and jumped back there was an eyeball filling the whole view. He looked through it and asked how I did that. He thought I was pranking him and I thought he was pranking me. He looked on the front lense and was baffled how I did it. He looked again and it blinked and he jumped back. It turns out the neighbors had horses standing in the woods and we setup the telescope zoomed in perfectly on one of there eyes. We couldn't believe it the odds of setting up a telescope perfectly focused on a horse eye miles away. This video just reminded me of it.

[@Vision-Vibes]

Wow you really found the needle in the haystack!

[@herbert993]

They often see plastic bags in bushes and immediately go into flight mode.

[@quackslikeaduck]

All due respect, you might want to check how to correctly say the word "peripheral".

[@Brambrew]

Horses also dont have great binocular vision and as a result poor depth perception, which is why they get freaked out by bodies of water if they can't see the bottom.

[@Vision-Vibes]

Makes sense!

[@billcook7483]

Why don't they have an extra 3rd eye in their forehead to eliminate the frontal blind spot ?

[@Vision-Vibes]

Great question. Come on horses, achieve your final form

Owls, or goats. Those rectangular irises scare me.

[@Vision-Vibes]

You got it! But I agree, those are freaky

[@averycheesypotato]

Most owls don’t have that feature, only some species

[@RichardCarter-y4m]

I believe that the horses retina is "ramp like" such that it can focus for close up and for in the distance. This is what is happening when they suddenly jerk their head up. What about a "look" at the octopus eye?

[@Vision-Vibes]

Oh cool. Yeah I think octopus would be a great one for this series too! I'll add them to the list 🐙

[@FlyingJuiceBox]

Horse eyes, like most mammal eyes also can rotate in the skull to keep the horizon level in the background. It's just very noticeable in horses because their eyes can be from 5-6ft up to less than 1ft from the ground, depending on whether the horse is looking around or grazing.

[@IzaiahYeguadaEspanol]

That’s fucking cool because I always wondered what my horses see and now I learned some new today thanks ❤️❤️❤️❤️👍💯💫

[@Frrk]

Was hoping for a bit more depth here. Why do pupil edges seem wrinkly? What is the anatomy like?

[@Vision-Vibes]

True, here I really focused on what it is they see rather than the anatomy of their eyes. I'll do a follow-up video diving into that!

[@gavincurtis]

Eye curtains that act like visors in a car to block sunlight? I don't know, I just stayed at a Motel 8...

[@ShaddySoldier]

Do other equines see this way as well? Ponies, zebras, donkeys, ect.

[@Vision-Vibes]

Yes! Zebras and donkeys have similar vision to horses

[@P.e.m.a.]

Even their eyeballs have horse teeth 😅

[@Vision-Vibes]

Yeah they have some freaky eyes!

[@danielhooke6115]

So... do big eyeballs let you see longer wavelengths?

[@Vision-Vibes]

It's not connected to the size of the eyeballs! The types of rods and cones (light-detecting cells) on an animals retinas determine what range of wavelengths they're sensitive to

[@paigemontague4022]

Did anyone else find the thumbnail a bit creepy? 😅

[@Vision-Vibes]

True that eye close-up is pretty creepy!

[@lasthopelost9090]

Yes I hate it

[@jz4087]

Important question. How exactly do you get this information? How do you know what they see?

[@rwquote]

A lot of tests and knowledge acquiring and saving

[@Vision-Vibes]

Scientists can tell how different animals see by either studying the structure of their eyes (looking for the number and layout of their rods and cones), and by doing tests like electroretinography where they sense their brain activity as they look at different visual stimuli

[@Digibeatle09]

Do I take it that - apart from size of the eye - what’s stated in this v. informative video applies to donkeys also ?

[@Vision-Vibes]

Their vision is pretty similar, but donkeys actually have a wider field of view than horses! Donkeys can see their hind feet when they're looking forward

[@LlamaStoleYourToast-tg1fx]

0:46 made my day better 😂❤️

[@Vision-Vibes]

Yeah that's a fun clip 😀

[@theshypersistence]

Why is the thumbnail so terrifying 😨

[@Vision-Vibes]

Because horse eyes are freaky!

[@Chewbakaya]

Biological things are always better looking from far away

[@yetanothertroll]

Apparently horses and other animals with horizontal bar shaped pupils aren't great at seeing vertical shapes like metal poles

[@CG-rr6yx]

The horizontal slit becomes almost vertical when the horse grazes. So, the animal, even with the head lowered to the ground, distinguishes better the vertical silhouettes of the predators moving horizontally.

[@yetanothertroll]

@CG-rr6yx No, their eyes rotate when their head's down to graze. Many other herbivores' eyes do the same. There's a study published in Science Advances about pupil shapes that goes into it, but YT doesn't like me posting direct links

[@CG-rr6yx]

@@yetanothertroll Even our eyes rotate a bit when we tilt our heads. I wasn't aware that herbivores' eyes can rotate full 90° .

[@AmilaA-yq9dl]

what about elephant eyes? aren’t those bigger than horse eyes?

[@Vision-Vibes]

Elephant eyes are actually smaller than horse eyes even though elephants are bigger animals! Elephant eyes are about 1.5 inches in diameter on average while horse eyes are about 2 inches in diameter on average

Mountain lions, wolves, and coyotes are ballsy enough to try and hunt horses!

[@drunkenskunkproductionsdsp8094]

Prehistoric humans used to hunt and eat the ancestors of horses, and some people eat horses now, but it's frowned upon in most places in the world.

[@agniavardanyan9284]

I've also read that horses can see everything below much more clearly, the higher up, the more blurred their vision is.

[@lorefreak94]

Horses may not see details well at a distance but it's like jurassic parks' Trex, they can spot movement in the distance really well. I would argue the great night vision part. Their dark vision seems pretty similar to our own.

[@bojeelll9192]

Is that why some trainers keep the horses eyes covered when they take him out of the barn so the eyes don't have to adjust

[@Vision-Vibes]

Exactly!

[@benrex7775]

You put in some embarrassing video clips. If I were a horse I would be ashamed right now. I'm from Switzerland and we have mandatory military service. I chose a unit where we use horses to transport materials through the mountains where the cars don't go. I was fascinated by the eye of the horse. Perhaps you can answer my question. What are those weird things standing up in the horse eye. If I remember corerctly, it can even go across the pupil. And what purpose does it serve?

[@Ferd414]

Those structures are known as "corpora nigra", which translates from the latin to "black bodies", and they perform a simlar function to your eyebrows - namely, reducing glare - but inside the eyeball, rather than external.

40 min to adjust to sudden changes in brightness? So it would be nice if you could gradually change the light level in a barn when it's morning or night. :)
