The location of hamster pupils is not always obvious, but can be seen clearly with an infrared camera.

SWEET MOTHER FUCKING LOL

But it scares me at the same time.

I'm pretty glad I can't see hamster pupils, as they are terrifying

Good god.

I had these albino (at least I think they were) hamsters with red eyes, now I'm wondering about their pupils...

Gah. Nightmares.

Remember that those are wide-angle lenses. Even though they're googley-eyed, they can still see pretty well for such a small mammal. They just have a very broad FOV due to all that exposed cornea and lens.

Good God. In the first pic, the hamster has the usual alert, inquisitve, intelligent rodent look, in the second one it looks stupid and slightly insane.

could you explain this "aiiiiirrrrr" thing? I've googled to no avail. Is it just choking, or a more involved meme?

It might as well be. Even though it looks like he's staring in two different directions, the hamster in the pic is looking straight ahead and taking in about a 160 degree FOV.

<- This image is a diagram of a typical rodent skull. It's a squirrel's, but similar enough to a hamster's that I can use it to make my point.

Note those HUGE orbits. Hamster eyes are adapted to seeing well at night (Because they're nocturnal) and underground (since they're burrowers.)

I've drawn a rough diagram below of the structure of a hamster eye. The red bit is the retina. The black dot is the pupil, almost completely obscured by the iris which is pretty normal when your under bright lights to get your picture taken.

Note that the iris does NOT restrict your field of view. It merely limits the amount of light that can come into your eye.

The green area is the minimum theoretical dilation of the hamster's eye, as would happen in very dark rooms, or underground. IE, his iris is open as far as possible to let in as much light as possible.

Due to the high curvature of the cornea, each hamster eye can take in more than 90 degrees of vision. Like all mammals, the center of the hamster's field of vision is focused on the center part of the retina, called the 'Fovea' in humans. The angular lines in my diagram represent the approximate refraction of light through the hamster's cornea and lens.

If this guy was not under bright lights, his irises would appear to be a great deal less dilated and less 'crazy'.

I wish there were good sites that show how different animals see, like giving a 3d VR type of comparison with a humans eyesight.

Comparing field of vision, hues, light, movements

so fucking interesting ;_;
