Mirror is a common pair of silver, mirrored aviator sunglasses but the lenses have been reversed so the mirror is facing the eyes. Sunglasses are an external device used to shade our eyes from the sun so we may see better during the day. As most products evolve they become more fashion conscious and often the more fashionable the less functional they become. If a person were to wear these glasses it would be nearly impossible to see anything but their own eyes. There would be a shift in focus from function and appearance to self. To see or be seen is the question.
