Eye tests aren’t just for doctor visits — sometimes they come as fun puzzles that test how well your eyes and brain work together. In this optical illusion, a number is hidden among a sea of red speckles. At first glance, the image looks like random noise, but if you look closely, a three-digit number emerges. Can you spot it? Why is it so tricky? The red dots create heavy visual noise, your brain struggles to recognize patterns, and the number is blended in with only slight tonal differences. Some people even find it easier to see when they glance indirectly instead of staring straight on.

Tips to help:
Soften your gaze instead of focusing too hard.
Step back or move closer to your screen.
Try squinting slightly to blur distractions.
Scan for small breaks in the pattern.
Still stuck? The hidden number is 571.

If you found it, congratulations — your observation skills are sharp! If not, don’t worry. These puzzles are meant to challenge, and with practice, you’ll get better at spotting hidden details. Optical illusions like this boost focus, patience, and visual acuity — plus, they’re just plain fun to share.
