Sungoggles are "high quality sunglasses" designed to protect the eyes from the harmful effects of solar radiation, ranging from visible light to UV, without impeding sight in the least.
Due to their light sensitivity, Yazirians are often seen wearing them even in urban settings.
Due to their extreme usefulness in blindness prevention, Sungoggles are often included in emergency survival kits.
Sungoggles are also used by interstellar travelers of all races to compensate for lighting conditions on different worlds caused by different stellar classes.
Purchased individually, sungoggles cost 2 Cr.
