Can dogs see glass, but cats are blind?

A debate is raging across the world on the different kinds of eyesight that our pets have. As usual, the internet is the best source for answers, but it’s not surprising that most of the information is just as inaccurate as the comments that follow. Read below and you’ll find the truth.

The kind of eyesight we humans have is called “binocular vision”, but even though that is the usual one described, the others are not that different and so it’s important to look into them.

Our usual eyesight is binocular vision, and most of us think that dogs have that, too. But what is binocular vision?

It’s where we use two images for each of our eyes, one for each eye. We see as the image of our eyes are focused in two separate places and then merged. This way we can judge where the object is placed.

This is great if it’s a still object (like a picture) but it isn’t so great if it’s something moving. If we can see where the object is coming from, we have a problem. If not, our only alternative is to have our eyes facing each other.

This sounds worse than it is because our eyes actually move quite a lot as we blink, but it’s usually not a problem with dogs, and for many it’s not even noticeable because they blink so often anyway.

So it’s not really that bad. But is it?

It actually is. To see if we can really compare the different kinds of vision in our pets, we need to know what they do with their eyes while they’re awake and alert, not while they’re asleep.

We’ll also need to know how they see.

The first one we’ll look at is our pets’ near-vision (or ‘low-vision’ if you want to get technical about it). This is when they focus their eyes on something from around 2-5 feet away and uses their brn to make sense of what they see.

For dogs, their near-vision is a bit like being on a good smartphone. They have a decent, if not great, camera. They’re pretty quick at getting the picture, but they’re nowhere near the megapixel’s of modern camera phones. So what they are, in many ways, is a ‘selfie’ camera.

They have a good camera, but they don’t zoom in, they don’t get great detl, and the background will be just as blurred. That’s what they’re good at and the more they do it, the better they get at it.

This is, in many ways, what their eyes do.

The second kind of vision we’ll look at is our pets’ foveal vision or ‘high-vision’. This is when they are really good at focusing their eyes on something and actually getting good detl.

This is what many people think of when they think of a cat’s vision. Their eyes are really big. So big, in fact, that they are actually seeing a scene from a wide angle of view. It’s much like a person would see in a football stadium.

This is when they really need their eyesight. They need to be able to see lots of detl, and as a result, can use their brn to help them make sense of what they see.

When they do this, they have a very keen sense of depth. When they focus on something they can very easily see a very clear 3D image of it. They can see it as if they were viewing it in a room or a landscape, rather than what you’d think of as a picture – a flat 2D picture on a page.

So it’s good to see them hunting, good to see them catching birds, etc. But what about when they’re just hanging out? You know, doing nothing. Just chilling.

If you were to look at a photo or video of them in this state, you’d likely see them looking at the ground – and this is true. But what they’re really doing is looking at a scene from a more distant 3D angle. This is why they can make very good use of their eyes – to see 3D depth – but they can also see objects as they would in a picture. They just see the objects at a different distance.

This is how they see the world.

Now the last kind of vision we’re going to cover here, is the one they do when they’re sleeping.

I’ll be honest with you, I don’t know much about it. But as you may have noticed, if you look at the side of your kid’s head, they’re looking to the left – like they’re looking at something behind you. And the reason for this is that they’re using this other kind of vision in their brns.

If we try to understand why this happens, I think that we’ll need to delve a little bit into the science behind it – just a little bit. So if you want to skip ahead, you can see what I’m talking about below.

As it turns out, the part of the brn that processes visual data is not located at the front of your head as you might think. It actually resides behind your eyes. In particular, it’s located just in front of the eyes in your brn’s visual cortex, or the ‘visual centre’.

And what the visual cortex does is it creates what’s called a model of the outside world. When you look out the window or look at the moon, you don’t really have to see the objects that you’re looking at. You have a sort of model of the outside world and you use that model to get a sense of depth.

For instance, it’s very hard to tell how far away a very small model of a dog is from you, if you’re looking at a full-sized dog. But if you think about the model of a dog that you have in your head, it’s probably a lot closer than the dog itself. So there’s a model of the dog in your brn, not in your eyes. And the way that your brn makes sense of that model is that the model must be positioned a certn distance away from you.

And this, it turns out, is the same way that you do depth perception. Your eyes don’t really need to see the objects that are coming toward you and you have no idea how far away they are from you, to make sense of the world. But your brn needs to do a certn calculation in order to figure out how far away objects are, and it does that by using an internal model. So, that’s what creates depth perception. And it also explns why things that are close to you seem to move much faster than things that are further away, or far from you.

Here’s a video that explns what I’m talking about, and it’s well worth watching:
