Scientists believe that all eyes developed nearly 600 million years ago from a simple, light detecting organism. As we know now, over those millions of years, eyes have become one of the most important and complex senses there are — and we’re not just talking about for humans.

We may not work on animal eyes here at Barry Wasserman’s, but that doesn’t mean we can’t still be amazed by the many eyes of the animal kingdom!

  1. Shark corneas are so similar to human ones, that they’ve been used in human cornea transplants.
  2. Worms don’t have eyes.
  3. Owls can see a moving mouse more than 150-feet away from it.
  4. Box jellyfish have 24 eyes.
  5. Guinea pigs may only have two eyes, but they’re born with them completely open.
  6. Owls are the only bird that can see the color blue.
  7. To give them a wider field of vision, goats have a rectangular pupil.
  8. The four-eyed fish can see above and below the water at the exact same time.
  9. Dragonflies have 30,000 lenses in each of its eyes.
  10. Dolphins must be pretty paranoid because they really do sleep with one eye open!
  11. Cuttlefish might be blind, but they can still perceive light and move according to it.
  12. A tiger’s night vision is six times better than a human’s.
  13. An ant may only have two “true” eyes, but each eye is made up of smaller eyes, which creates a compound eye.
  14. An ostrich’s eye is bigger than its brain.
  15. The Giant Squid holds the record for the largest eye. At 18 inches wide, it’s about the size of a watermelon.
  16. Dog’s can’t tell the difference between red and green (which probably makes Christmas pretty confusing for them).
  17. Despite their incredible night vision, cat’s can’t see in total darkness. But when they can’t see, they can still use their whiskers to navigate.
  18. A gecko’s eyesight is 350 times more sensitive to color than a human’s.
  19. The jumping spider can also see many more colors than a human and in greater detail and vibrancy.
  20. Snakes have two sets of eyes, a daytime pair and a night-time pair.
  21. Many insects have evolved to have 360-degree vision — something they need to better protect themselves.

Unlike the cute, slimy, cuddly, and flying creatures we mentioned above, you have the power to improve your eyesight in the blink of an eye — so what are you waiting for!?
