IMO i think we need a .sunglasses command. I know they had them in WW2 because the sunglasses where invented by the japanese in 1430 by smoking the glass, worn by judges to conceal there expressions. (just a little history fact)
With World War II brewing in 1936, Ray Ban designed anti-glare aviator style sunglasses, using polarized lens technology newly created by Edwin H. Land, founder of the Polaroid Corporation.
They also designed a slightly drooping frame perimeter to maximally shield an aviator’s eyes, which repeatedly glanced downward toward a plane's instrument panel. Fliers were issued the glasses at no charge, and the public in 1937 was able to purchase the model that banned the sun's rays as Ray-Ban aviator sunglasses.
