Do Guinea Pigs Have Eyelids?

|

Yes guinea pigs do have eyelids.

In fact they have two sets of eyelids: an upper and a lower.

The upper eyelid is called the “palpebra” while the lower eyelid is called the “nictitating membrane.”

Interestingly guinea pigs are the only rodents that have a nictitating membrane.

This is a third eyelid that helps to protect the eye and keep it moist.

It’s located in the inner corner of the eye and you may have noticed it when your guinea pig has been sleeping.

So now that we know that guinea pigs have eyelids what do they do with them? Well just like our eyelids guinea pig eyelids help to protect the eye.

They also help to keep the eye moist by spreading tears over the surface of the eye.

If you’ve ever wondered why your guinea pig’s eyes sometimes look wet it’s because they are! Guinea pigs produce tears constantly and these tears help to keep the surface of the eye lubricated.

In addition to keeping the eye moist tears also help to remove dirt and debris.

So if your guinea pig’s eyes ever look dirty it’s a good idea to clean them with a soft damp cloth.

Now that you know all about guinea pig eyelids you can rest assured that your furry friend’s eyes are well-protected!

Guinea pigs do have a row of eyelashes that protect their eyes but they do not have actual eyelids.

The reason for this is that guinea pigs have evolved to have very large eyes in order to help them see in the dark.

If they had eyelids their eyes would be much smaller and they would not be able to see as well.

Instead their eyelashes help to keep dirt and debris out of their eyes and they also help to protect their eyes from the bright sunlight.

While guinea pigs do not have eyelids they do have a third eyelid which is a thin membrane that covers the eye when they blink.

This third eyelid helps to keep the eye moist and protected and it also helps to remove any debris that may have gotten into the eye.

So while guinea pigs do not have eyelids they do have a third eyelid that helps to protect their eyes.

Their large eyes and long eyelashes help them to see in the dark and to keep their eyes safe from the bright sunlight.
