D&D 3.0: Tales from Mystara
Eye of the Eagle
Eyes of the Eagle – These items are made of special crystal and fit over the eyes of the wearer. These lenses grant a + 5 circumstance bonus to 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 the character covers his or her other eye. Of course, the wearer can remove the single lens and see normally at any time, or wear both lenses to end or avoid the dizziness.
