We’ve got a passion for improving human eyesight here at Barry Wasserman’s office, but we also love reading about the weird and wonderful facts about eyesight for the rest of the animal kingdom! Here are the oddest facts we’ve discovered recently!

The Weird Animal Eyesight Facts

The dragonfly has multiple eyes. The dragonfly’s eyes in particular are large and intricate, covering most of the head. Their amazing field of vision covers 360 degrees!

We bet you never knew that starfish have eyes! In fact, they have five eyes, one located on each of the starfish’s arms. Their vision is not as sharp as human sight—starfish can only use their eyesight to sense lightness and darkness.

Chameleons’ eyes are distinct in that they move all over the place, and independently of each other. This unique characteristic is what allows the chameleon’s vision to reach 360 degrees.

What We Mean When We Say “Eagle-Eyed”

The eyes of the eagle are nearly as large as a human’s, and they do see color. But, the eye of the eagle sees things four times sharper than a human with perfect 20/20 eyesight. The eagle’s vision is so acute that this bird can see prey from more than a mile away and 1,000 feet in the air.

If you thought eagles had good eyesight, the hawk is even more impressive. A hawk’s vision is eight times better than humans. While perfect vision for humans is 20/20, a hawk’s vision could be as perfect as 20/2 (meaning they see at 20 feet with the same acuity as what we see at two feet). Hawks actually have eye muscles not found in other animals that enhance vision.

The Crazy Facts About Mammal Eyesight!

Many mammals including leopards see colors, just not as many as humans do. But that’s okay, since these cats don’t depend on seeing colors to fulfill their primary purpose: hunting. Instead, leopard’s eyes contain light sensitive cells. As a result, leopards have incredible night vision that allows them to sense even the slightest movement. Vision is one of the traits that make leopards the best hunters.

Tigers and humans have something in common: they both have binocular vision, meaning they use both eyes together. The use of depth perception allows the tiger to be the ultimate hunter. Their feel for proper distance between predator and prey is a survival skill. Like humans, the tiger’s eyes help the cat see in three dimensions!

The wolf’s eyes are made to sense any movement. Wolves see in three dimensions with a maximum of a 180-degree field of vision. Wolves’ eyes are golden in color—and unlike humans, wolves NEVER have blue eyes.

Like the house cat, ALL mountain lion kittens are blind at birth, and upon opening their eyelids for the first time have blue eyes. As the cat matures, the eyes change to a greenish gold color.

Goats’ eyes are rectangular. While goats don’t have quite the field of vision as dragonflies, their eyesight covers a wider angle of view than humans. Because the pupils are huge, goats also have excellent night vision.

Believe me Cheryl, if LASIK could make our eyes superhuman, the first patients would be LASIK surgeons!
