  • Better Instructions:

    Full screen, pause when there is only an X and a O on the screen. Begin close to the screen looking at the O with your right eye and your left covered, or at the X with your left eye. Now slowly back up until the symbol your not looking at disappears.

  • where the optic nerve attaches the the eye that area doesnt have recepters, damn good job we have two eyes ;¬)))

  • it doesnt disapear :/

    

  • Freaking awesome!!

  • Yes my nose was in the way when i was very close

    ( and i dnt have a jew nose)

  • This is so cool!

  • you have to adjust your open eye at exactly 90 degrees from the X or O you are looking at!!!

  • you need to adjust your distance from the screen sometimes. I had this in my Biology 30 text book. It worked if I pulled the text book to about 20cm from my eyes. Works here too.

  • nah that was shite u little fart bubble

  • Interesting...

  • the moment the image strikes the optic disc also known as the "blind spot", the image will disappear, because the optic disc contains no photoreceptor(cons & rods).

  • what is the sound?
