If You Can Conquer These 20 Optical Illusions, Then You're A Master Of The Deceptive Arts
"Illusion is the first of all pleasures"
If you focus on the white shapes, you'll see a series of columns, but take a moment to look at the black space and you'll also see pairs of people in conversation.
Straight into the curve
Relax your eyes and you'll see the grey lines curve even though they're completely straight.
Yes, it does look like this picture is moving, but if you focus intently on one spot, it'll freeze for you.
As you scan across the grid, they should change from white to black as they enter your peripheral vision.
These lines look like a crooked mess, but they're all perfectly straight diagonal lines with distorting hashmarks.
Pink, green, gone?
If you focus on the black cross, you'll notice green dots replacing the pink. Focus for a bit longer and the pink dots will disappear all together.
See the difference fade by placing your finger between the two at the arrows.
Which line is longer?
This simple illusion leads you to believe the bottom line is longer thanks to the positioning of the arrows inward or outward while they're actually the same length.
Which way is she spinning?
If the grounded foot is thought to be the left, she's spinning clockwise, while if you glance away and consider the grounded foot as the right, she spins clockwise.
While you will naturally see one option, look away, and refocus to get a view of both options.
The intersect of black and white trick your eye into thinking there are grey dots where there aren't.
They're actually the same size, though the surrounding circles lead you to believe that the right is larger.
Count the circles.
You may think we're asking to count the wrong shape, but if you take a closer look, there are more circles than you may expect.
Believe it or not, the "blue" and "green" spirals are actually the same light teal color.
If you look closely, you'll see that an orange strip passes through the "green" and pink spirals, and skips over the "blue" spiral seriously changing how we perceive the color relative to those near it. Don't believe me? Check out this explanation.
Stare at the black bulb for about 30 seconds and then immediately switch your attention to a light surface and you should see the bulb all light up!
