Optical illusion makes Twitter community doubt their senses. A photo with a black and gray spiral went viral on social media.
Munich – Anyone who recognizes a number is already right. But this optical illusion is amazing. Some claim to only see “528” in the center of the spiral, others report seeing entirely different sequences of numbers. Users on Twitter rack their brains over the visual puzzle. Thousands of answers seem possible. Twitter user “benowine” shared the mystery, and reactions followed promptly.
Who sees through? How many numbers can you see
Which number or digits most can recognize at first glance is different. Sometimes there are only three numbers, but others see a much longer series of numbers, for example “45283”.
Some Twitter fans quickly doubted their eyesight because they could only see a few numbers or none at all when looking at them. “I can only see 528. Does that say anything about my vision?” asks a Twitter user. Of course, a suggestion follows to have an eye test done. And indeed, anyone who has difficulties with contrasts will have a hard time.
Optical illusion: how well do you recognize contrasts?
Contrast sensitivity allows us to distinguish objects from their background. This eye function pays off in certain situations.
If you have a higher contrast sensitivity, you can better perceive the position of objects in poor lighting conditions, haze or fog, for example. Better recognize the difference between what is in the foreground and what is in the background.
In the visual puzzle, people with a strong sensitivity to contrast can see the digits better. By the way, there are seven. Those whose eye function is less pronounced in this area may only be able to make out shorter sequences. This optical illusion tricks the human eye with the lines and the spiral.
If eyes have low contrast sensitivity, those affected may find it difficult to drive at night. Low contrast sensitivity can be a symptom of certain eye diseases. These include cataracts, glaucoma or diabetic retinopathy.
Optical illusion: who recognized the number they were looking for?
At first glance, however, most people only see a three-digit number. Very few people immediately recognized the seven-digit number they were looking for: 3452839.
Optical illusions: Stunning videos and photos trick our brains
Maybe someone remembers a video with a horse? The direction in which the horse is trotting should give an indication of the viewer’s* preferred brain half. The human brain obviously works differently for everyone, as the discussion “What color is the dress” showed years ago. (ml)*Merkur.de is an offer from IPPEN.MEDIA
