Force Blinding

Force Blinding uses a blinding flash of energy emanated from a user's hand, manifested as a flash of light that overloads a target's vision, causing temporary blindness. A powerful tool of the Light Side, a Force-user can obfuscate an opponent's sight, making it difficult for the adversary to spot and attack the user or anyone else.

However, trained Force-sensitives who have prepared themselves can defend against this technique by using Force Sight. It is ineffective against those who are blind, lack eyes, or who use some sense other than sight as their primary means of navigation.
