A mind-boggling social media post from a Japanese professor went viral over the weekend.

It stated: “When the white disks in a scintillating grid are reduced in size, and outlined in black, they tend to disappear”. Move your eyes around and you will see other dots emerge as you focus on different parts of the image. Most viewers can see just a couple of black dots at a time. The image even made it to Twitter on September 12 and has been retweeted over 33,600 times and has more than 32,000 ‘likes’. Interestingly, whether you can see through this particular meme might indicate the health of your vision, or at least your color-sensitivity. However, brain uses its own understanding to make the best guess about what’s most likely to follow.
There are 12 dots in all, but you can not spot all of them at once. At certain crossings, there are back dots (12 in the original image) that seem to blink in and out of existence as the eye scans over the picture. (That was shared more than 20,000 times, and liked by about 155,000.) A hint: The phone’s patterned case is very similar to that of the rug, but they don’t perfectly match up.
So can you spot the household pet perching in the picture below? Your brain just interprets it that way.
In this optical illusion the black dot in the centre of your vision should always appear but, because humans have bad peripheral vision, the dots around the centre ones disappear. The illusion was sourced from a Facebook post, according to Kerslake.

You’ll feel like you need an eye exam after you study this optical illusion.
