Optical Illusion Eye Test!
Today’s optical illusion is not just a treat for your eyes; it is a challenge for your brain. At first glance, the image seems like a perfectly organised sea of red and cream circles, each containing either the number 16 or 19. It’s neat, repetitive, and oddly satisfying. But hidden in this numerical ocean is number 17.
Sounds simple? Not quite.
This puzzle is designed to test your focus, patience, and attention to detail. As your eyes dart across the pattern, they quickly adapt to spotting only the 16s and 19s. Your brain, in a bid to save energy, starts ignoring minor differences—and that’s when the 17 slips through unnoticed.
Optical illusions like this one are more than just fun distractions—they’re actually excellent cognitive workouts. They test your visual acuity, pattern recognition, and even your resistance to cognitive bias. In this case, your mind gets used to seeing only two numbers and assumes the rest will follow suit.
Still can’t find it?
Scan the image from top to bottom instead of left to right. Sometimes breaking the way you usually look at things can make all the difference.
These kinds of puzzles are used in everything from memory training apps to neuropsychological assessments, and for good reason. They’re engaging, frustrating, and rewarding—all at once.
So, did you find the hidden 17? Or is it still playing hide and seek with your eyeballs? If you’re truly stuck, look slightly right of centre, around the middle row.
Let us know how long it took you to find it, and don’t forget to share it with a friend who thinks they’ve got sharp eyes.
