These lenses are small, clear, crystalline constructions set into a golden frame.

When you place these lenses over your eyes, they become all but invisible (Spot DC 30 to notice). While wearing the lenses, you gain a +10 circumstance bonus on Spot checks to see through a disguise. This is a continuous effect and requires no activation.
In addition, once per day you can activate the lenses to force a single shapeshifted creature within 30 feet to resume its natural form. The target creature can attempt a DC 14 Will save to resist.
Failure means it immediately assumes its natural form, shape, and size, and it cannot assume a different shape for the next 2d4 rounds.

Prerequisites: Craft Wondrous Item, true seeing, dispel magic or greater dispel magic.
Cost to Create: 5,000 gp, 400 XP, 10 days.
