The thing about eyewear is that it is so potent, There are very few accessories that, if you were not wearing anything, if you put on they would date you to a whole era. You could look the Thirties, the Fifties, and the Nineties just by your eyewear. It's like a pair of shoes because it is sculptural. It exists without a face. It tells a lot about where you are architecturally or aesthetically in a particular period in time.
