When Lucius Domitus Ahenobarbus, more commonly known as Roman Emperor Nero, used emerald lenses to view gladiator games in ancient Rome. His precious gem lenses, which didn't necessarily help him see any better, became an instant, must-have fashion accessory.

Nero perhaps should be remembered as one of Italy's earliest fashion trendsetters.
