Eye protectors

An old steel case for safety goggles. Even though the history of such devices goes back to a patent for "eye protectors" awarded to African-American inventor Powell Johnson in 1880, the technology to produce impact-resistant or ballistic eye protectors had to await developments in World War II, and safety glasses weren't in general use in industry until the 1940's.
