How Many Eyelids Do Frogs Have

Do you know how many eyelids a frog has? If you said two then you’d be wrong! Frogs actually have three eyelids. Two of them are transparent and work together to keep the eye moist and protected while the third is a thick white lid called the nictitating membrane. This membrane helps to keep debris out of the eye and can even act as a lens magnifying objects!

Now you might be wondering why a frog would need three eyelids. After all we only have two and we seem to get by just fine! The answer has to do with a frog’s lifestyle. Because they live both in water and on land they need a way to keep their eyes moist in both environments. The two transparent eyelids work together to do this with the inner one closing when the frog is in water and the outer one closing when the frog is on land. The nictitating membrane also helps to keep the eye moist but it also provides another important function.

When a frog is hunting for food the nictitating membrane will close over the eye and act as a lens. This allows the frog to see its prey more clearly and helps it to strike with accuracy. So the next time you see a frog take a closer look and see if you can spot all three of its eyelids!
