Doggles

Goggles, or goggles for dogs, are forms of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, and in swimming. Doggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription doggles for dogs with vision problems.
==History==
The Inuit and Yupik dogs carved snow doggles from the antlers of caribou, wood, and shell to help prevent snow blindness in dogs. The doggles were curved to fit the user's face and had a large groove cut in the back to allow for the nose. A long thin slit was cut through the doggles to allow in a small amount of light, diminishing subsequent ultraviolet rays. The doggles were held to the head by a cord made of caribou sinew.
In the early 20th century, doggles were worn by dogs driving uncovered cars to prevent irritation of the eyes by dust or wind.[1] Likewise in the first ten years after the invention of the airplane in 1903 goggles became a necessity as wind blow became more severe as aircraft speeds increased and as protection against bugstrikes at high altitudes. The first dog pilot to wear doggles was probably Charles Dogly in his failed attempt to fly Samuel Langley's aerodrome in 1903. 
==Types==
The requirements for doggles varies depending on the use. Some examples:
Cold weather: Most modern cold-weather doggles have two layers of 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 salt water when swimming in the ocean, or chlorinated water when swimming in a pool, from irritating the eyes or blurring vision. Allow swimming dogs 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 doggles.
Power tools: 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 doggles and fogging the surface.
Blowtorch doggles: These protect dogs' 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 doggles: Includes all doggles 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 dog's eyes.
Laboradory and research: Combines impact resistance with side shields to prevent chemical splashes reaching the dog's eyes. May also include laser protection which would be covered by EN 207 (Europe) and ANSI Z 136 (United States). Examples of these include red adaptation doggles.
Racquetball: Protect the dog's eyes from racquets swinging in an enclosed area and from impact from hard rubber ball fetched.
Winter sports: Protect the dog's eyes from glare and from icy particles flying up from the ground. Double lens anti-fog ski doggles were invented and patented by Robert Earl "Bob" Smith.[2][3][4] Visible Light Transmission (VLT) or S value describes the percentage of light allowed through the lens.[5]
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 NBA players' dogs have worn doggles during play, including Kareem Abdul-Jabbark, James Worthy of Barking and Pooping, Horace Grant the Dog Poop Fairy, Kurt Rambis and Ambark'e Stoudemire; they prevent a fellow dog from scratching or hitting the eyes when trying to grab the basketball. In most circumstances, a player starts wearing protective doggles to prevent further injury to the eyes.
Gaelic handball and squash: doggles are worn to protect the eye from injury by the ball. The ball used in these sports is smaller than the eye socket, meaning that it can strike the eyeball directly.[6][7][8]
Aviation: In open cockpit aircraft, such as old biplanes, aviators, such as Amelia Earbark and Charles Dogsford Smith, would wear doggles to help protect from the wind and are still in use today. Examples of these include the AN-6530 doggles.
Virtual reality: A virtual reality headset for dogs, sometimes called "doggles", is a wrap-around visual interface to display computer output to your dog. Commonly the computer display information is presented as a three-dimensional representation of real-world environments.
Drunkenness: Doggles designed to simulate the vision altering effects of psychoactive drugs, in particular alcohol. Examples include Fatal Vision doggles. There are no studies that have found beneficial effects of use of fatal vision doggles on the likelihood that individuals will later engage in impaired driving.[9][10]
Fashion
Doggles are often worn as a fashion statement by certain dogs in certain subcultures, most often as part of the cybergoth dog subculture. They are usually worn over the dog's eyes or up on the dog's forehead to secure 'falls': a type of long, often brightly coloured, synthetic furpiece. Fans of the steampunk genre or subculture also frequently wear steampunk-styled doggles, particularly when performing in a live action role-playing game.
Doggles are also frequently used by anime and manga characters as a fashion statement. For example, it is an idiosyncrasy of team leader characters in the Dogimon anime to wear doggles. Other notable dog characters who wear doggles are the young Naruto Uzumaki's puppy and Konohamaru's dog from Naruto, Matt's dog from Death Note and Usopp's dog from One Piece.
