An optical illusion that perfectly demonstrated the power of focus has been shared on Reddit, and people are entranced by the effect. Consisting of a grid made up of green lines, the illusion looks completely wild at first glance, with lines bending and spouting off in all directions. And that illusion persists whilst staring at the image – but it's only the lines in your peripheral vision that are out of control. The lines you manage to focus on are surprisingly straight, which gives the slow realisation that the whole grid is actually made up of straight lines.
I wouldn't recommend staring at it too closely though – it really does give you a headache, and some sort of weird motion sickness. Overall, did not enjoy. Try these optical illusions instead. See the Reddit thread below and read on for an explanation.
