Force power "sight" is perhaps the most under used neutral force power. Which is a shame. This force power counters two light force powers, "blinding" and "persuasion". If you have the force power activated before some one attempts to blind you, you will suffer no ill effects. If you know there is a jedi using force power "persuasion" in the area, using force power "sight" will allow you to see them. Another aspect of force power "sight" is that when you have the map overlay, you will see all items and the location of all players. This is useful if you want to know if a jedi is in the next room behind the door. You will also be able to tell what direction they are facing.
