Testing 1, 2, 3, ....

Our sense of vision allows us to see the world around us. The organs that help us to see are our eyes.  We can detect objects, colors, motion and the world around us using our sight. The human eye does a great job of giving us visual information, but it is not perfect, there are areas of the eye that do not see images due to our blind spots. In this activity, we will search for our blind spot and see how that has an affect on what we see.
