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.
 Notable wearers are: Audrey Hepburn, Jacqueline Kennedy Onassis, Paris Hilton, Nicole Richie, Sophia Loren and Victoria Beckham.
A corrective lens is a lens worn in front of the eye, mainly used to treat myopia, hyperopia, astigmatism, and presbyopia.
 Glasses or "spectacles" are worn on the face a short distance in front of the eye.
 Contact lenses are worn directly on the surface of the eye.
 Intraocular lenses are surgically implanted most commonly after cataract removal, but recently for purely refractive purposes.
 Myopia (near-sightedness) requires a divergent lens, whereas hyperopia (far-sightedness) requires a convergent lens.
Dame Edna Everage is a character created and performed by Australian comedian Barry Humphries, famous for her lilac-coloured or "wisteria hue" hair and cat eye glasses or "face furniture", her favourite flower, the gladiolus ("gladdies") and her boisterous greeting: "Hello, Possums!"
 As Dame Edna, Humphries has written several books including an autobiography, "My Gorgeous Life", appeared in several films and hosted several television shows (on which Humphries has also appeared as himself and other alter-egos).
Cat eye glasses are a shape of women's and sometimes men's eyewear.
 They have an upsweep at the outer edges where the temples (commonly referred to as the arms) join the frame front.
 They were mainly popular in the 1950s and 1960s among fashionable women and are usually associated with the Beehive hairstyle.
 They preceded the large bug-eye glasses of the 1970s, 1980s, and 1990s.
 Notable wearers of cat eye glasses include: Audrey Hepburn, Barry Humphries as Dame Edna Everage, Jane Jacobs, Amy Lame, Lisa Loeb, Dinah Manoff, Elizabeth Taylor, Marilyn Monroe, Mary Whitehouse, and Barbara Windsor.
Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears.
 Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness.
 Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses.
 Some types of safety glasses are used to protect against visible and near-visible light or radiation.
 Glasses are worn for eye protection in some sports, such as squash.
 Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports.
 Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.
Rev Bruce Kenrick (18 January 1920 – 15 January 2007) was an English social activist and Minister in the United Reformed Church and the Church of Scotland.

Cat eye syndrome (CES), or Schmid–Fraccaro syndrome, is a rare condition caused by the short arm (p) and a small section of the long arm (q) of human chromosome 22 being present three (trisomic) or four times (tetrasomic) (usually 3 times) instead of the usual two times.
 The term "cat eye" syndrome was coined because of the particular appearance of the vertical colobomas in the eyes of some patients.
 However, over half of the CES patients in the literature do not present with this trait.
 There is no significant reduction in life expectancy in patients who are not afflicted with one of CES' life-threatening abnormalities.

Constance Mary Whitehouse, CBE ("née" Hutcheson; 13 June 191023 November 2001), better known simply as Mary Whitehouse, was an English social activist known for her strong opposition to social liberalism and the mainstream British media, both of which she accused of encouraging a more permissive society.
 She was the founder and first president of the National Viewers' and Listeners' Association, through which she led a longstanding campaign against the BBC.
 A staunch social conservative, she was disparagingly termed a reactionary by her socially liberal opponents.
 Her motivation derived from her traditional Christian beliefs, her aversion to the rapid social and political changes in British society of the 1960s and her work as a teacher of sex education.
Lensless glasses are glasses that lack lenses.
 They are worn solely for aesthetic or fashion purposes, having no function in vision correction or eye protection.
 The frames are usually oversized, and commonly all black in color.
 They may be worn in conjunction with contact lenses.
 Advantages of lensless glasses are that they do not fog or reflect, and there is no lens that will touch long eyelashes and eyelash extensions.
