A STRANGE optical illusion can reveal if you are ‘blind curvature’.
It’s the name of a mind trick that makes you see angles instead of curves.

This Optical Illusion Can Trick You Into Seeing Zigzag Lines
The terrifying trick was devised by experimental psychologist Kohske Takahashi and is called the “curvature blindness illusion.”
Depending on the types of lines you see in the image above, you may be ‘blind curvature’.
Don’t worry, it’s not a medical condition, just the name given to this interesting mind trick.
Takahashi describes the trick in the research paper as “a wavy line is perceived as a zigzag line.”
Look at the image and determine if you see straight zigzags, softer rounded waves, or both.
Especially when they look at the gray part of the image.
But if you look closely, you should be able to see that all the lines are exactly the same soft, curvy waves.
Many of us will still see sharp zigzag patterns in the gray area, even now that we know the lines aren’t actually that shape.
This is called “curvature blindness,” and Takahashi believes it may be due to how we perceive the difference between angles and curvature in the real world.
When we look at an optical illusion and its different patterns and colors, our brain’s visual system can get confused.
Shades, colors, and different levels of brightness can be used to trick the brain.
Takahashi wrote in his study: “We propose that the underlying mechanisms for the perception of smooth curvature and those for the perception of obtuse angles compete with each other in an unbalanced manner.”
He suggested that angle perception might be more dominant in the brain.
The psychologist previously told The Telegraph: “I would say perhaps our eyes and brains are evolutionarily adapted to detect angles more effectively than curves.
“We are surrounded by artificial products, which have many more angles than [the] the natural environment does it, and therefore our vision.
“This visual phenomenon does not create a problem in our daily lives, otherwise someone should have found this illusion earlier.”
