These items are made of special crystal and fit over the eyes of the wearer.

These lenses grant a +5 competence bonus on Spot checks. Wearing only one of the pair causes a character to become dizzy and, in effect, stunned for 1 round. Thereafter, the wearer can use the single lens without being stunned so long as she covers her other eye. Of course, she can remove the single lens and see normally at any time, or wear both lenses to end or avoid the dizziness.

Prerequisites: Craft Wondrous Item, clairaudience/clairvoyance.
Cost to Create: 1,000 gp (plus 500 gp for base item), 80 XP, 2 days.
