SRD:Seeing

Seeing: This kind of armor grants a wider than normal field of vision, so that opponents flanking the wearer gain only a +1 bonus on their attack rolls instead of +2 (rogues still get their full sneak attack damage because the wearer is still flanked). The wearer gains a +1 enhancement bonus on Spot checks but takes a –2 penalty on saves against gaze attacks.

Faint clairsentience; ML 5th; Craft Psionic Arms and Armor, ubiquitous vision; Price +6,000 gp.
