Ok, I'm finally catching up with the rest of the crowd and reading a steampunk book. I'm enjoying it, but - okay - if the purpose of your particular special eyewear is to let you look through special lenses, rather to protect your eyes from harm, why oh why are they goggles instead of glasses? And why is everybody else in town also wearing goggles instead of glasses? Is metal and metalwork free or something? Are noses and ears made out of bone, in this alternate reality, instead of cartilage, so the extra weight is no biggie?
