British WW2 Anti Gas Glasses Tinted and Clear survival According to JBM BallisticsThe British WW2 Anti Gas Glasses were issued to soldiers during World War II as a protective measure against gas attacks. The glasses came in two variants, one with clear lenses and the other with tinted lenses for use in bright sunlight. The glasses were designed to protect the eyes from harmful gases that could cause irritation and blindness. They were typically made with frames and hinged sides, allowing the lenses to be folded flat for storage.
