Editing Goggles (section)

== Types ==
The requirements for goggles varies depending on the use. Some examples:
* Cold weather: Most modern cold-weather goggles have two layers of [[Lens (optics)|lens]] to prevent the interior from becoming "foggy". With only a single lens, the interior [[water vapor]] condenses onto the lens because the lens is colder than the vapor, although [[anti-fog]] agents can be used. The reasoning behind the dual layer lens is that the inner lens will be warm while the outer lens will be cold. As long as the temperature of the inner lens is close to that of the interior water vapor, the vapor should not condense. However, if water vapor gets between the layers of the lens, condensation can occur between the lenses and is almost impossible to get rid of; thus, properly constructed and maintained dual layer lenses should be airtight to prevent water vapor from entering between the lenses.
* [[Swimming]]: Must be watertight to prevent water, such as [[Seawater|salt water]] when swimming in the [[ocean]], or [[Chlorine|chlorinated]] water when swimming in a pool, from irritating the eyes or blurring vision. Allow swimmers to see clearly underwater. They will not be usable more than a few feet underwater, because the water pressure will press them tightly against the face. (Below this limit, a [[diving mask]] must be used, which allows the user to equalize pressure by exhaling air through the nose.) Examples of these include [[Swedish goggles]].
* [[Power tool]]s: Must be made of an unbreakable material that prevents chunks of metal, wood, plastic, concrete, and so on from hitting or piercing the eye, usually [[polycarbonate]].  Usually has some sort of ventilation to prevent sweat from building up inside the goggles and fogging the surface.
* [[Oxy-fuel welding and cutting#Safety|Blowtorch goggles]]: These protect the eyes from glare and flying sparks and hot metal splashes while using or near a [[blowtorch]]. They are not the correct filters for [[arc welding]].
* [[Welding helmet|Welding goggles]]: Includes all goggles for eye protection during welding or cutting. They provide protection against debris, the heat from welding, and, with the proper filters, the optical radiation resulting from the welding, which can otherwise cause [[arc eye]].
* [[Motorcycle]] riding and other open-air activities: Prevents insects, dust, and so on from hitting the eyes.
* [[Laboratory]] and [[research]]: Combines impact resistance with side shields to prevent chemical splashes reaching the eyes. May also include [[Laser safety|laser protection]] which would be covered by [[EN 207]] (Europe) and ANSI Z 136 (United States). Examples of these include [[dark adaptor goggles|red adaptation goggles]].
* [[Racquetball]]: Protect the eyes from racquets swinging in an enclosed area and from impact from hard rubber ball.
* [[Winter sports]]: Protect the eyes from [[Glare (vision)|glare]] and from icy particles flying up from the ground. Double lens anti-fog ski goggles were invented and patented by Robert Earl "Bob" Smith.<ref>{{cite web |url=https://www.foxsports.com/olympics/story/ski-goggle-pioneer-bob-smith-dies-042712 |title=Ski goggle pioneer Bob Smith dies |work=Fox Sports |date=2012-04-27 |access-date=2020-06-25 |archive-date=2020-06-27 |archive-url=https://web.archive.org/web/20200627233231/https://www.foxsports.com/olympics/story/ski-goggle-pioneer-bob-smith-dies-042712 |url-status=live }}</ref><ref>{{cite patent|country=US|number=4528701|pubdate=1985-07-16|title=Goggle with a renewable protective surface|inventor1-last=Smith|inventor1-first=Robert E.}}</ref><ref>{{cite patent|country=US|number=4428081|pubdate=1984-01-31|title=Goggle with a renewable protective surface|inventor1-last=Smith|inventor1-first=Robert E.}}</ref> Visible Light Transmission (VLT) or S value describes the percentage of light allowed through the lens.<ref>{{Cite web|url=https://www.sport-conrad.com/|title=Sport Conrad|website=www.sport-conrad.com/|access-date=2020-11-13|archive-date=2019-07-30|archive-url=https://web.archive.org/web/20190730112307/https://www.sport-conrad.com/|url-status=live}}</ref> 
* [[Astronomy]] and [[meteorology]]: [[dark adaptor goggles]] are used before going outside at night, in order to help the eyes adapt to the dark.
* [[Basketball]]: Several [[National Basketball Association|NBA]] players have worn goggles during play, including [[Kareem Abdul-Jabbar]], [[James Worthy]], [[Horace Grant]], [[Kurt Rambis]] and [[Amar'e Stoudemire]]; they prevent a fellow player from scratching or hitting the eyes when trying to grab the basketball. In most circumstances, a player starts wearing protective goggles to prevent ''further'' injury to the eyes. They are typically fitted with [[polycarbonate]] lenses to ensure impact resistance.
* [[Gaelic handball]] and [[squash (sport)|squash]]: goggles are worn to protect the eye from injury by the ball. The ball used in these sports is smaller than the [[Orbit (anatomy)|eye socket]], meaning that it can strike the eyeball directly.<ref>{{Cite web|url=https://theracketlife.com/best-squash-goggles/|title=Best Squash Goggles|first=Zeid|last=Kaddoura|date=December 28, 2022|website=The Racket Life|access-date=February 20, 2023|archive-date=February 20, 2023|archive-url=https://web.archive.org/web/20230220121200/https://theracketlife.com/best-squash-goggles/|url-status=live}}</ref><ref>{{Cite web|url=https://www.opticianonline.net/features/sports-injuries-never-saw-coming|title=Sports injuries: 'I never saw it coming' - Optician|website=www.opticianonline.net|access-date=2023-02-20|archive-date=2023-02-20|archive-url=https://web.archive.org/web/20230220121114/https://www.opticianonline.net/features/sports-injuries-never-saw-coming|url-status=live}}</ref><ref>{{Cite web|url=https://imj.ie/epidemiology-of-injury-in-gaelic-handball/|title=Epidemiology of Injury in Gaelic Handball – Irish Medical Journal|access-date=2023-02-20|archive-date=2023-03-28|archive-url=https://web.archive.org/web/20230328145404/https://imj.ie/epidemiology-of-injury-in-gaelic-handball/|url-status=live}}</ref>
* [[Aviation]]: In open [[cockpit]] aircraft, such as old [[biplane]]s, [[Aircraft pilot|aviators]], such as [[Amelia Earhart]] and [[Charles Kingsford Smith]], would wear goggles to help protect from the wind and are still in use today. Examples of these include the [[AN-6530 goggles]].
* [[Virtual reality]]: A virtual reality headset, sometimes called "goggles", is a wrap-around visual interface to display computer output. Commonly the computer display information is presented as a three-dimensional representation of real-world environments.
* [[Alcohol intoxication|Drunkenness]]: Goggles designed to simulate the vision altering effects of [[psychoactive drug]]s, in particular [[Alcoholic beverage|alcohol]]. Examples include [[Fatal Vision (goggles)|Fatal Vision goggles]]. There are no studies that have found beneficial effects of use of fatal vision goggles on the likelihood that individuals will later engage in impaired driving.<ref name="MeekerSI">{{cite journal |last1=Meeker |first1=Miranda |last2=Kehl |first2=LeAnna |title=Substance use: Are specialized goggles effective at preventing impaired driving |journal=[[Skeptical Inquirer]] |date=2020 |volume=44 |issue=3 |page=56}}</ref><ref name="Jewell1">{{cite journal |last1=Jewell |first1=J |last2=Hupp |first2=S.D. |title=Examining the effects of fatal vision goggles on changing attitudes and behaviors related to drinking and driving |journal=Journal of Primary Prevention |date=2005 |volume=26 |issue=6 |pages=553–565|doi=10.1007/s10935-005-0013-9 |pmid=16228116 |s2cid=19762828 }}</ref>
