Fun Visual Illusions

Fun Visual Illusions

Fun Optical Illusions for Everyone!

The way our brains perceive certain images can sometimes be a bit tricky. Optical illusions are visually perceived images that differ from objective reality. Meaning, we see and perceive something to be one way, but when we measure it or compare it to a known standard, it differs from our perception. Check out the image on the left - Would you say those lines are straight or slanted? Use a straight edge, line it up with the bottom of your monitor, and you'll find that the lines are exactly straight, despite our perception that they are slanted at an angle. To view some more mind-bending visual illusions that will leave you scratching your head, read on...

See the blocks marked "A" and "B"? Believe it or not, these are the exact same shade of grey!

Both orange dots are the exact same size.

Despite what you may think, the gray bar is the same shade of gray throughout.

Duck or rabbit??

Try and count the black dots (hint: they don't actually exist on the image!).

The red lines, despite appearances, are all exactly straight!
