VISOR
A visor (also spelled vizor) is a surface that protects the eyes, such as shading them from the sun or other bright light or protecting them from objects. Nowadays many visors are transparent, but before strong transparent substances such as polycarbonate were invented, visors were opaque like a mask * The part of a helmet in a suit of armor that protects the eyes. *A type of headgear consisting only of a visor and a band as a way to fasten it around the head. *Any such vertical surface on any hat or helmet. *Any such horizontal surface on any hat or helmet (called a ''peak'' in British English). *A device in an automobile that the driver or front passenger can lower over part of the windshield to block the sun (sun visor).

Sun Visor
A sun visor is a component of an automobile located on the interior just above the windshield (also known as the windscreen). They are designed with a hinged flap that is adjustable to help shade the eyes of drivers and passengers from the glare of sunlight. Design Starting in 1924, automobiles such as the Ford Model T began to include an exterior sun visor on its closed body versions. Other early automobiles also had externally attached sun visors to their windshields until 1931, when interior mounts were introduced. As automobile design advanced with windshields mounted on an angle to lessen wind resistance, the outside or "cadet-type" sun visors were no longer seen on cars starting from 1932. Henceforth, sun visors were mounted inside the vehicle, making the hinged flap easier to reach and adjust. Most modern cars have two sun visors, one for the driver's side and a second for the passenger's side, with the rear-view mirror often mounted in between the two sun visors. Each ...

Hats
A hat is a head covering which is worn for various reasons, including protection against weather conditions, ceremonial reasons such as university graduation, religious reasons, safety, or as a fashion accessory. Hats which incorporate mechanical features, such as visors, spikes, flaps, orthodontic headgear, braces or party hat, beer holders shade into the broader category of headgear. In the past, hats were an indicator of social status. In the military, hats may denote nationality, branch of service, rank or regiment. Police typically wear distinctive hats such as peaked caps or brimmed hats, such as those worn by the Royal Canadian Mounted Police. Some hats have a protective function. As examples, the hard hat protects construction workers' heads from injury by falling objects, a British police Custodian helmet protects the officer's head, a sun hat shades the face and shoulders from the sun, a cowboy hat protects against sun and rain and an ushanka fur hat with fold-down ...

Visard
A visard (also spelled vizard) is an oval mask of black velvet, worn by travelling women in the 16th century to protect their skin from sunburn. The fashion of the period for wealthy women was to keep their skin pale, because a tan suggested that the bearer worked outside and was hence poor. Some types of vizard were not held in place by a fastening or ribbon ties, and instead the wearer clasped a bead attached to the interior of the mask between their teeth. The practice did not meet universal approval, as evidenced in this excerpt from a contemporary polemic: A visard recovered from inside the wall of a 16th-century building in Daventry, England. In Venice, the visard developed into a design without a mouth hole, the ''moretta'', and was gripped with a button between the teeth rather than a bead. The mask's prevention of speech was deliberate, intended to heighten the mystery of a masked woman even further. A Spanish observer at the wedding of Mary I of England and P ...

Accountants
An accountant is a practitioner of accounting or accountancy. Accountants who have demonstrated competency through their professional associations' certification exams are certified to use titles such as Chartered Accountant, Chartered Certified Accountant or Certified Public Accountant, or Registered Public Accountant. Such professionals are granted certain responsibilities by statute, such as the ability to certify an organization's financial statements, and may be held liable for professional misconduct. Non-qualified accountants may be employed by a qualified accountant, or may work independently without statutory privileges and obligations. Cahan & Sun (2015) used archival study to find out that accountants’ personal characteristics may exert a very significant impact during the audit process and further influence audit fees and audit quality. Practitioners have been portrayed in popular culture by the stereotype of the humorless, introspective bean-counter. It has bee ...

Green Eyeshade
Green eyeshades are a type of visor that were worn most often from the late 19th century to the mid-20th century by accountants, telegraphers, copy editors and others engaged in vision-intensive, detail-oriented occupations to lessen eye strain due to early incandescent lights and candles, which tended to be harsh (the classic banker's lamp had a green shade for similar reasons). Because they were often worn by people involved in accounting, auditing, economics, and budgeting, they became associated with these activities. Green eyeshades were often made of a transparent dark green or blue-green colored celluloid, although leather and paper were used to make the visor portion as well. One manufacturer, the Featherweight Eyeshade Company, described their eyeshade as "healthful, color peculiarly restful to the eyes". Green eyeshades are still on the market, typically sold as "dealer's visors". They retain some popularity in the gambling community. Several individuals, including Wil ...

Eyeshield
An eyeshield is a piece of football equipment that is also referred to as a visor that was created in the 1980s. In the mid 1990s as an effort to prevent brain and head injuries, headgear became mandatory in the game of football. The eyeshield was created to protect the eyes of football players during games and practices. It is a curved piece of plastic that attaches to the front of a football helmet. Safety equipment such as the facemask, eyeshields, and other face shields have been adopted over time to prevent player injury. The eyeshield leaves the mouth exposed, but covers the eyes and nose. The piece of equipment is made from various materials and by many different brands. Only clear eyeshields are permitted for use in high school football games due to the fact that eyes are needed to be seen while checking for a concussion. For college level players, the eyeshield may be tinted for players with eye problems. Production The first football visors were made by Oakley. Eyesh ...

Face Shield
A face shield, an item of personal protective equipment (PPE), aims to protect the wearer's entire face (or part of it) from hazards such as flying objects and road debris, chemical splashes (in laboratories or in industry), or potentially infectious materials (in medical and laboratory environments). Depending on the type used, a face shield may protect its wearer from a physical hazard, chemical splashes, or biological hazards. Industry A face shield is intended to protect the wearer's partial or entire face and the eyes from hazards. Face shields should be used with spectacles and/or goggles. Standards ;ANSI (American Standard) * Mark Z87: Basic impact: Faceshields shall be capable of resisting impact from a 25.4 mm (1 in) diameter steel ball dropped from a height of 127 cm (50 in). * Mark Z87+: High impact: Faceshields shall be capable of resisting impact from a 6.35 mm (0.25 in) diameter steel ball traveling at a velocity of 91.4 ...

Riotsquad Helmet
A riot protection helmet is a type of helmet designed for law enforcement and military use to protect its wearer's head, face and eyes from handheld melee weapons, and thrown projectiles such as bricks, as may be met in riot control. Many modern riot squad helmets are reinforced with materials that will protect the wearer from dangerous substances such as acids or industrial chemicals. The riot protection helmets are usually made to be able to easily fit a Gas mask, especially when tear gas is being used. There have been rare cases of riot protection helmets being worn to protect against objects blown by tornadoes or fierce storms for example in England in the 18 January 2007 gale. Description The simplest form is a hard shell with reinforced padding, and a chinstrap and a hinge-up (usually polycarbonate) visor, as in this image. These riot protection helmet visors are usually curved sideways and straight up-and-down, not curved both ways like on the older type of motorcycle h ...

Motorcycle Helmet
A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries. Motorcycle helmets consist of a Polystyrene, polystyrene foam inner shell that absorbs the shock of an impact, and a protective plastic outer layer. Several variations exist, notably helmets that cover the chin area and helmets that do not. Some helmets provide additional conveniences, such as ventilation, face shields, sun visors, ear protection or intercom. Origins The origins of the crash helmet date back to the Brooklands race track in early 1914, when a medical officer, Dr. Eric Gardner, noticed he was seeing a motor cyclist with head injuries about every two weeks. He got a Mr. Moss of Bethnal Green to make canvas and shellac helmets stiff enough to stand a heavy blow and smooth e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Visor (ice Hockey)
A hockey helmet is worn by players of ice hockey, inline hockey, and bandy to help protect the head from potential injury when hit by the puck, sticks, skates, boards, other players, or the ice. The shell of a hockey helmet is generally made of a substance called vinyl nitrile that disperses force from the point of contact, while the liner may be made of either vinyl nitrile foam, expanded polypropylene foam, or other material to absorb the energy, to reduce the chances of concussion. Hockey helmets grip the head from inside by cupping the back of head, or the occipital protuberance. Helmet manufacturers will have a chart that relates their helmet sizes to head measurements. Mt on older models, the helmet size is adjusted by loosening the screws on the side to slide the front portion forward or back. Visors and shields A visor or face shield in ice hockey is a device attached to the front of a helmet to reduce potential of injury to the face. Visors cover the upper half ...

Windshield
The windshield (North American English) or windscreen (Commonwealth English) of an aircraft, car, bus, motorbike, truck, train, boat or streetcar is the front window, which provides visibility while protecting occupants from the elements. Modern windshields are generally made of laminated safety glass, a type of treated glass, which consists of, typically, two curved sheets of glass with a plastic layer laminated between them for safety, and bonded into the window frame. Motorcycle windshields are often made of high-impact polycarbonate or acrylic plastic. Usage Windshields protect the vehicle's occupants from wind and flying debris such as dust, insects, and rocks, and provide an aerodynamically formed window towards the front. UV coating may be applied to screen out harmful ultraviolet radiation. However, this is usually unnecessary since most auto windshields are made from laminated safety glass. The majority of UV-B is absorbed by the glass itself, and any remaining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
