Cool Facts About Dolphin Eyes - Part 3



“A dolphin’s pupil has a type of built-in shade. When our eyes are exposed to light, our pupils get smaller to let less light in. Dolphins have a kind of lid, called an operculum, that slides down to cover most of the pupil when it is bright. It almost looks like two pupils when this ‘lid’ comes down.”
-          Joy Clausen Soto, Senior Dolphin Trainer at SeaWorld

Humans don’t have instant shades on our eyes. We have to wear sunglasses to protect our eyes from the harsh sun. When you are nearsighted, farsighted or have astigmatism, it’s often necessary for you to purchase expensive prescription sunglasses to be able to see in sunlight.

LASIK has allowed millions of Americans to expand their sunglasses collections with a multitude of cheap sunglasses by correcting their refractive errors.

In a LASIK procedure, a surgeon creates a thin flap on the cornea that is peeled back to allow access to the underlying corneal tissue. This can be done using a microkeratome or femtosecond laser. Once the flap has been created, an excimerlaser is used to reshape the cornea (correct the refractive error) so it can properly focus light on the retina (the back of the eye). This is the actual vision correction step in the procedure. Once the cornea is reshaped, the flap is put back into place so it can heal. The entire procedure only takes minutes per eye.

Like any surgical procedure, LASIK does carry risks. You should always have an open discussion about all of the risks of LASIK with your surgeon before you make any decisions to move forward with the procedure. You should also remember that even if you have 20/20 vision, it’s still important to wear sunglasses to protect your eyes. You’re not a dolphin, after all!
