SRD:Eyes of Expanded Vision

Eyes of Expanded Vision: These crystal lenses fit over the user’s eyes to expand his field of vision. Flanking opponents gain only a +1 bonus when attacking the user 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 1st; Craft Universal Item, ubiquitous vision; Price 3,000 gp.
