Opening the third eye is very simple. Just because the third eye is open, however, does not mean any 'enlightening' experience will take place. That involves meditation and knowledge of spiritual exercises.
Easiest way to open the third eye, place a penny on your lower forehead, right above your brow, or try it with a small round magnet. You will feel it immediately and from there you can exercise the experiences you have.
