A martial artist's vision is their greatest asset. To be able to quickly visually discriminate between one thing or another could be the difference between life and death. Below is a graphic that is taking the internet by storm. The faster one can find the panda means that they have what Furuya Sensei used to call, "A discriminating eye."
Here is how I suggest you do it.
1) Look away from the graphic for at least one minute. 2) Look at the graphic but let your eyes blur out the details by looking slightly above the picture for 10 seconds. 3) Then while your vision is blurred change your focus to the center and let your eyes sharpen. 4) You should be able to pick out the panda in just seconds without scanning the picture.
