Do you still remember the clothes that went viral on the internet more than 5 years ago? Do you believe it is yellow and white or black and blue? Another eye-catching tweet is currently trending. It’s a meme that says: “So far, no one has found the right number.” The image used in the meme is black and white with diagonal zigzag lines on it. The optical illusion created by these lines leads to specific numbers. What’s the problem? No one can agree on the solution because some people are seeing many different solutions. Benonwine, a Twitter user, shared this now famous image and he asked his followers about the number they observed. As you might expect, a discussion ensued. The tweet currently has 4,581 likes, 1,286 replies and 1,226 retweets. People respond with a series of numbers, ranging from three to seven digits, with countless possible combinations. The most popular answers are 15283, 845283 and 45283. And as we all know, the real question of which number is likely to happen is never resolved on the internet. Naturally, some Twitter users were humorous in their comments. Others are so dedicated that they even experiment with other techniques, such as head tilts, eye closures and visual movements, in an effort to recognize the right number. “Scroll down the image quickly – then I can see 2 more!!!,” one user tweeted in response. What is the correct answer? The correct answer seems to be 3452839, despite all the wildly different answers. By adjusting the contrast of the image, you can find out. What is contrast sensitivity? Yes, this idea refers to the ability to distinguish an object from its surroundings. The opposite of eyesight, it (how clearly you see things from a distance). You can have excellent eyesight but poor contrast sensitivity, and the reverse is also true. Like astigmatism, contrast sensitivity is a refractive defect. In essence, it prevents light from focusing properly on your retina. By using a chart with letters that gradually fade from black to gray, doctors can check for this. In the end, however, these are just a few entertaining optical illusions for Internet users to enjoy and maybe even learn something new. What number do you see then? ?
