Although we have 5 different senses and each of them allows us to interact with the world in a unique way, the one that most of us appreciate is our vision. Without being able to see, we would have a difficult time getting through life and that is why we often take care of our vision, avoiding too much eyestrain and having our vision tested on a regular basis.
Maintaining healthy vision is obviously going to benefit us, but it is also something that we may end up taking for granted. As our eyes begin to deteriorate due to aging, overexposure or eyestrain, however, we become more tuned in to the need to take care of this vital sense. That is what this test is designed to do. It can test our eyes and see if it is necessary to have them checked further by a professional.
This test is easy to take. As long as you can see, you can focus on the image and try to look beyond to see what is hidden behind it. Most people will be able to see it, even though it is rather subtle. Try to figure out what you are seeing and then look for the answer to check what is actually hidden.
