Wraith goggles
From The Stargate Omnipedia
Device worn over the eyes of Wraith hunters while they hunt Runners. The headset likely aids in targeting long-range, and may display information which improves firing accuracy in other ways.
The goggles appear to be used only in daylight. When light is low -- or nonexistent -- a commander can rely upon ocular implants built into his eyes.
KEY EPISODE
