1-With this one, you want to focus your attention on the black plus sign in the center of the circle. As the pink circles spin and fade in and out, they will eventually start alternating between pink and green. (by Jeremy L. Hinton)



2-This image is not moving. I’ll leave it at that. Sorry if you get a headache from this one.



3-Focus on the blue dot at the bottom right of the image. Don’t take your eyes off that dot. As you concentrate on that, the moving gray bar will eventually appear blue although the color 
doesn’t actually change.



4-Negative images make for great optical illusions. Stare at the red dot on the young woman’s nose for thirty seconds. When thirty seconds is up, look to a solid, plain surface like the wall, floor or ceiling. Close and open your eyes repeatedly. You’ll see the image in full color! Click the photo for a bigger version if the smaller version doesn’t work for you



5-Focus on this image for thirty seconds. After thirty seconds look away and turn your attention to a flat, plane surface like the wall, floor or ceiling. Close and open your eyes repeatedly. You’ll see the Italian flag in full color!



6-Stare at the flag for thirty seconds. When thirty seconds has passed, look at a flat surface such as the wall, floor or ceiling. Close and open your eyes repeatedly. You’ll see the US flag in full color.



7-The red and blue lines are different lengths, right? Wrong. Aside from color, both lines are exactly the same.



8-It might appear that these lines are bent but that isn’t the case. The background in this image causes distortion giving the viewer a skewed view by creating false depth. These lines are all in fact straight.



9-Looking at these lines, it’s pretty obvious that the horizontal lines are bent but in truth, they’re not.



10-A blue dog and a yellow dog, right? Nope! Both dogs are the same color. As with some of our other color illusions you can use your favorite photo editing software to confirm.
