What number do YOU see?

This optical swirl illusion which hides some digits has gone viral on Twitter. It is not only hypnotic. This swirl may reveal some surprising information about your own vision.

The puzzle was tweeted by @benonwine who reached thousands of Twitter fans from all over the world since it became viral, and has reached widely divergent opinions about the concealed figures. The grey and white stripes are arranged in irregular spirals, making identifying the number more difficult.

According to Mail Online, this illusion operates by manipulating contrast sensitivity, which is often considered to be a critical indicator of visual function.
