Can you get the curve right?
Your eyes are deceiving you.
Although some of these lines appear to be curved, it is actually a grid of straight lines.
That’s because the illusion relies on a strategic arrangement of colors and shapes to trick your brain.
Scientists have previously explained that the illusion can occur when your brain guesses what’s happening in an image while you’re only looking at a part of it.
Illusionist Michael Bach offered an explanation on his blog.
“It can be made more noticeable by applying a small amount of blur (4–5). Blur happens automatically in our visual system because, mostly imperceptibly, our visual resolution drops rapidly from the center of view: to 10° of eccentricity, our visual acuity is 1/10 of the central one.
“However, the periphery doesn’t ‘feel’ blurry, right? Its sharpness is ‘invented’ by our visual system, just like our blind spots are ‘filled in.’
Bach’s theory suggests that the lines in the illusion aren’t really curved the way your brain tells you.
