Test Your Blind Spot

Alright, right now you can see both an x and circle. Close or cover up one your left eye. Now SLOWLY move your head closer to the screen and stay focused on only the X. As you get about six inches from the computer screen, you'll see that the circle has actually disappeared. You just found your blind spot!

You'll find that different people have their blind spots in different areas, so have your friends try this eye trick and see how far away from their screen they were when the circle disappeared.
