Bug-eye glasses are distinguished by the size of their lens, being large enough to cover the entire eye.
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.
Bug-eye sunglasses lenses are larger than regular eyeglasses, and today's oversize-framed eyeglasses have inherited the look and feel of bug-eye eyewear, gradually incorporating modern, trendy design concepts to enhance the wearer's personalized look and protect them from UV rays.
Notable wearers are Audrey Hepburn, Jacqueline Kennedy Onassis, Paris Hilton, Nicole Richie, Sophia Loren and Victoria Beckham.
