Most Amazing Animal Eyes

Most Amazing Animal Eyes

If I hold up a crayon and tell you it’s purple, you’ll say, “Okay.” But, what does purple really mean? It’s probably a different experience for each of us.  Every human being sees the world differently.

 

If you’ve ever wished you could see through another person’s eyes, imagine what it would be like to use the eyes of a completely different creature. Below I’ve listed five of the most optically incredible animals in the world. Have a look, learn how they work, then close your eyes and try opening theirs!

 

Frogs

Frogs (and toads) keep their eyes on top of their heads, which gives them enormous range of vision. This interesting positioning, believe it or not, also helps with digestion. When these animals swallow, they pull their eyes into their head to help push food into their stomachs. Bet you’ve never eaten with your eyes before!

Geckos

Geckos (specifically, the leaf-tailed variety above) might look strange, but their eyes make sense. The twisty patterns help to camouflage them from predators. They also hide many small openings, similar to our pupils, which let in more light than ours. They are able to see vivid colors, even in very dim places.

Cuttlefish

Cuttlefish are colorblind, but don’t let that fool you. Their unique eyes see light polarization instead, making them unrivaled at determining contrast between dark and light areas. Also, you’ll notice that interesting “w” shape in their lids. That’s because cuttlefish can’t focus their pupils as humans do. They reshape their entire eye to help focus!

Insects

Insects come in many varieties, but what we’re really interested in are their compound eyes. Compound eyes allow insects to see in a wide range all around them. Their vision isn’t as clear as ours, but if you can see a giant thing swatting at you from behind, you can’t waste too much time wondering what it is! They also keep an extra pair (or three) of plain old simple eyes on their heads for clarity.

Owls

All birds of prey have eyes that are both flat and wide, allowing them to see impeccable detail at great distances. After all, they need to be able to swoop out of the sky and catch mice from thousands of feet in the air. But, the owl has the additional advantage of night vision. No animal can see in complete darkness, but give an owl a sliver of light, and it will do what falcons and eagles can only do in daylight.
