Pig Goggles also know as Onassis glasses or "Jackie O's" are very large sunglasses worn generally by unattractive women. This style of sunglasses is said to mimic the kind most famously worn by Jacqueline Kennedy Onassis. While originally worn by Onassis in the 1960's, the glasses eventually became popular with younger American girls around the year 2003. Big sunglasses have maintained their popularity through 2007. They have also expanded their demographic reach to adult women throughout the world. Modern day celebrities use these to hide from paparazzi but they are mostly favoured by visually unfortunate woman for the purpose of hiding the face, the glasses create the illusion of a aesthetically pleasing face as they only reveal the mouth and tip of the nose and give the impression of perfect symmetry for upper facial and bone structure which according to the golden ratio theory is the most important part of the face for creating aesthetics. The glasses are also known as reverse beer goggles and are disfavoured by males as they cause unnecessary head turning and checking out of unattractive females that from even short distances may appear attractive, numerous reputable mens magazines have called for a ban on the glasses.
