Eye sacks were small sacks under Yuuzhan Vong eyes. Colored blue or sometimes purple, they gave the Yuuzhan Vong the appearance of dark circles. They pulsated slightly in response to the Yuuzhan Vong's emotional state. Eye sacks were also considered a mark of beauty among female Yuuzhan Vong; the bluer the sacks, the more attractive.
