Blake Lively Is Driving Everyone Insane With This Optical Illusion

By

Shout out to Blake Lively for both making me worry about my eyes and giving me a headache with this Instagram post.

If you're a true '90s kid, you might remember a little book series called "Magic Eye."

If you're NOT a true '90s kid, please hand in your birth certificate before reading the following explanation of what "Magic Eye" is.

Basically, it was just pages and pages of various patterns, and you were supposed to focus your eyes in a certain way that would reveal a hidden image within the pattern.

Not to brag or anything, but I was kind of a beast at this game when I was a kid. To this day I blame these things for my -8.75 glasses prescription.

That's why it's so frustrating I can't get the Magic Eye that Blake Lively posted on Instagram on Tuesday to work for me.

As part of a promotion for her upcoming film "The Shallows," the 28-year-old actress uploaded an image of this glittery blue pattern.

Supposedly, if you do it right, you'll be able to see a shark jumping out of the water.

Here's what you have to do to see the hidden image, straight from the Magic Eye website:

Hold the center of the printed image right up to your nose. It should be blurry. Focus as though you are looking through the image into the distance. Very slowly move the image away from your face. [...] Once you perceive the hidden image and depth, you can look around the entire 3D image. The longer you look, the clearer the illusion becomes. The farther away you hold the page, the deeper it becomes. Good Luck!

BUT NO MATTER WHAT I DO, I CAN'T FREAKIN' SEE THE SHARK.

The comments on Blake's post only make it more frustrating since so many people CAN see the shark, apparently. Those of us who can't, however, are left in despair.

Listen. I have tried everything. I have stuck my nose on my computer screen many, many times in the past hour, in full view of my co-workers. I have tried it on mobile. I have tried taking out my contacts. I have periodically stopped writing this article to try it once again every few minutes.

And all I have to show for it is a piercing headache and a sense of defeat.

THANKS A LOT, BLAKE LIVELY.
