These black lensed goggles are vaugely similar to WWII aviator goggles, or thats what some primes once told me. Not every race that walks the planes is comfortable out in sunlight. For some, it can be downright lethal. Others, not so much.These black goggles are specifiacly designed for making the wearer immune to dazzling light effects. For most, it is merely a defense against annoying flare spells and bright lights. For those who have a neutral sensitivity to light, these are a necessitity, unless they do a lot of travel by night.
