Gesicht mit Brille
Some people use glasses not because of their problems with eye-sight. They wear it as a fashionable item. The smile in dark glasses never really spent hundreds of years hiding in a bunker — it doesn't need to protect its eyes from the sun rays. He just wants to look like a boss. Other emojis are not preoccupied with eye problems either. They rather personify a nerdy and snobbish character.
