These sunglasses were part of the survival rucksack flown on the Apollo 15 mission in July 1971. They are made of ultra-violet filtering plastic and yellow coated nylon. An elastic and velcro strap secured them in place, providing the astronauts with the maximum amount of eye protection.
These sunglasses were transferred from NASA to the Smithsonian in 1978.
