These Optical Illusions Will Reveal A Secret About The Health Of Your Eyes


It’s important that you regularly get your eyes tested to make sure everything is in working order.

Our bodies are constantly changing, and this includes our eyes. One minute we could have perfect vision, and the next three months we could be short-sighted.

That’s why it’s important to keep up with the health of our eyes.

Most people use a simple chart in the doctor’s office to find out if our eyes are healthy or not.

The whole process may seem simple to us, but there are some eyesight tests that are far trickier than others.

A large number of people who try this particular test, for instance, discover they have more trouble with their eyesight than they expected!

Check out these tricky tests below.

Do you have what it takes to pass them? Well, good luck! You’re going to need it!

When it comes to examinations, the eye exam is likely the easiest one you’ll ever take—at least for those of you with really good vision.

Really, all you have to do is cover your eye with one hand and read a chart from top to bottom. Pretty simple, right?

Well, you might want to reconsider that. 

As it turns out, not all eye examinations are created equal. Honestly, anyone can read a bunch of letters on a board, but there are some tests out there that test more thoroughly.

Are you ready to take an exam yourself?


For this exam, all you have to do is spot the letter hidden in this picture in under seven seconds and you win.

But trust me, it’s not as easy as you think. Give it a shot!

Did you find it?

It’s the letter “C,” it’s tucked between the bottom right corner and center of the puzzle!

You could actually consider an optical illusion to be an eye test, while it may but your brain and perception to the test, it also tests your vision.  

Here’s another vision test that has stumped a lot of people on the Internet.


 First, just stare at the large red circle for a few seconds. Now, what do you see?

Don’t try to rush it or you’ll completely miss it!

You might see a little shape or even a blob, but there’s much more to it than! 

This blob will soon become clear to you, revealing the outline of a horse.

When more details are filled in, you can really see that there was much more to the outline than just its shape! You’ll soon see that the horse is even wearing a saddle!


This next puzzle actually tests people’s ability to detect light sensitivity. It lists five numbers, letters, or symbols in a row, each one is a shade lighter than the one to its left.

Are you ready?

The images become increasingly harder to decipher as the exam goes on. But it’s thought that people who are able to recognize the fifth number or symbol in one of the rows are said to have higher sensitivity to color than people who don’t!

Were you able to catch the last number or symbol in those series? Let me know your answers in the comments!


This next photo became a major viral hit a few years back, but it actually does reveal a lot about the health of your eyes and your vision.

Now tell me, what color is the dress?
