Bug-eye glasses: Bug-eye glasses are a form of eyewear.  They were popular in the 1970s, 1980s and 1990s, and were used for regular glasses and sunglasses.  They first became popular in the mid-1970s, and succeeded the cat eye glasses of the 1950s and 1960s.  In the 1970s, they were more of a square shape, and then later evolved into the more characteristic, larger, rounder and more familiar bug-eyed style of the 1980s.  Their popularity began to decline later, as glasses became easier to get and more affordable.  They were fashionable for men and women and are still fashionable today but as retro sunglasses.  They were followed by the thick-rimmed, rectangular styled glasses of the 2000s.
