Force power "blinding" is an underused light force power. If you use force power "blinding", you can counter four force powers "pull", "grip", "throw" and "deadly sight". Each force power requires line of sight and will be cut-off or won't work in the first place if you use this force power. The force power is also useful in one on one combat. At high level, if your opponent doesn't have force power "sight" enabled, they won't be able to see a thing for about 30 seconds. This makes them a sitting duck for powerful weapons, or even sabre damage.
