Optical illusion shows hidden number – not everyone sees the same

Optical illusions are famous for tricking our eyes and minds. They challenge what we see and make us question reality. Right now, a special optical illusion is taking over the internet. It’s simple at first glance but leaves most people puzzled.

The Hidden Message Illusion

Optical illusions come in different forms. Some make you search for mistakes. Others hide answers in plain sight. This illusion falls into the second category. It tests how well you can see contrasting colors.

The Illusion Test

When you first see this illusion, it looks easy. But the longer you look, the more confusing it gets. The answer is not what most people expect.

Look at the optical illusion. Do you see a number? What number do you see?

The Challenge

This illusion has gone viral on Twitter. It looks simple but is more challenging than it seems. A striped grey and black circle hides a number. Can you see the full number?

Understanding Contrast Sensitivity

This illusion tests your contrast sensitivity, which is your ability to see objects clearly against their background. In everyday life, this is important for tasks like driving in foggy weather or in low light. In such conditions, the contrast between objects and their background is lower.

Viewer Responses

Can you see all the digits? Here are some responses from viewers:

“I can only see 528. Does that mean anything about my eyesight?” – @CookieLousie

“I see 528 with glasses and 45283 without… I can’t read a screen without glasses however.” – @Techn0phobe

“45283…and what’s the catch? Should I book an appointment with my GP?” – @PhilippeAuclair

Most viewers saw either 528 or 45283. But the real answer is surprising.

The Answer Revealed

The actual answer is 3452839 – a seven-digit number. Most people only saw the numbers in the middle, where the contrast was highest. As you move away from the center, the contrast becomes weaker, making the digits on the edges hard to see. If you squint, you might be able to see all the numbers.

If you managed to see all the digits, you have amazing eyesight. Share this optical illusion with friends and family to see how their eyesight compares!
