Viral Optical Illusion: Nobody Has Found the Right Number

VIVA – An optical illusion on Twitter is going viral because it contains a riddle to be solved. The tweet caption says "So far, no one has found the right number,".

The tweet containing the optical illusion image is black and white with diagonal zigzag lines on it. This optical illusion is then blocked by the lines to produce a specific number. So, where's the problem?

As reported by the Times of India, Tuesday, December 27, 2022, the problem is that no one can solve the solution even though several people have provided various solutions. The tweet, shared by the @benonwine account, asked its followers what number they saw in the image.

Until today, the tweet has 4,581 likes, 1,286 answers, and 1,226 retweets. People on social media have responded by guessing various numbers, ranging from three to seven digits, with countless possible combinations.

The most people-guessed answers included 15283, 845283, and 45283.

Some Twitter users were clever in their comments. Others employed various strategies to see the numbers, from tilting their heads, to close their eyes, to moving pictures.

So, what is the right number? Have you found it out yet?

Yes, despite all the vastly different responses, the correct answer is 3452839. By adjusting the contrast of the image, you can more easily figure it out. What is contrast sensitivity?

This idea refers to the ability to distinguish an object from its environment. Unlike visual acuity (how you see something from a distance) you can have good visual acuity, but poor contrast sensitivity, and the reverse is also true.

Like astigmatism, contrast sensitivity is a refractive defect. Essentially, it prevents light from confusing properly on people's retinas. Using a chart with characters that gradually transition from black to gray, where doctors can test them.

But in the end, these are just some optical illusions that internet users can enjoy, or maybe you can even learn something new. Well, what number do you see?
