Visors
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). *As masque costume, Henry VIII and his courtiers wore "visors of good proportion of physiognomy".Richard P.

Sun Visor
A sun visor is a component of an automobile located on the interior just above the windshield (also known as the shield). 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 vis ...

Eyeshield
An eyeshield, also referred to as a visor, is a piece of gridiron football equipment that was invented 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 because eyes need 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. Eyeshields can be ...

Visor (armor)
A visor was an armored covering for the face often used in conjunction with Late Medieval war helmets such as the bascinet or sallet. The visor usually consisted of a hinged piece of steel that contained openings for breathing and vision. Appropriately, ''breaths'' refers to the holes in the metal of the visor. Visors protected the face during battle and could be remarkably durable. One surviving artifact was found to be "equivalent in hardness to cold worked high speed steel." __FORCETOC__ History The first recorded European reference to a helmet's visor in the Middle Ages is found in the 1298 will of Odo de Roussillon, which speaks of a ''heume a vissere''. Whether this statement refers to a pivoting visor or a fixed faceplate is not clear; but by the early fourteenth century artistic depictions of moving visors appear quite frequently. The popularization of the visor also increased the practical value of armorial surcoats in battle, since when the visor was down "it was no long ...

Eye Protection
Eye protection is protective gear for the eyes, and sometimes face, designed to reduce the risk of injury. Examples of risks requiring eye protection can include: impact from particles or debris, light or radiation, wind blast, heat, sea spray or impact from some type of ball or puck used in sports. Eye protection are typically separated into categories based on the style of eye wear and the hazard they are designed to reduce. There categories include: Spectacles with side protection; Goggles; Welding helmet; Welding Hand Shields; Non-Rigid Helmets (hoods); Face shield; and Respirator Face pieces. Styles Spectacles Safety glasses or spectacles, although often used as a catch-all term for all types of eye protection, specifically revers to protective equipment that closely resembles common eye wear. To meet most national standards, spectacles must include side shields to reduce the ability of debris to get behind the lenses from the side. Safety glasses can often moun ...

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. 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 of t ...

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. However, only 10.4% of all motorcyclists wear helmets, according to the World Health Organization in 2016. 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 a wireless microphone. 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 we ...

Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate ester, carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, toughness, tough materials, and some grades are optically transparent. They are easily worked, injection molding, molded, and thermoforming, thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code, resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confer rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate ester, carbonate groups (−O−( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Eyeshade
Green eyeshades or dealer's visors are a type of visor that were worn most often from the late 19th century to the mid-20th century by accountant 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 Certif ...s, 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 translucent dark green- or blue-green-colored celluloid, although leather and paper were used to make the visor portion, as well. One manufacturer, the Feat ...

Riot Helmet
A riot protection helmet or riot helmet is a type of helmet designed for law enforcement and military use to protect the 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 ...

Peaked Cap
A peaked cap, peaked hat, service cap, barracks cover, or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor, or peak, which was historically made of polished leather but increasingly is made of a cheaper synthetic substitute. The term forage cap is also used, although that also applies to the "field service cap" or the side cap. Other principal components are the crown, band, and insignia, typically a cap badge and scrambled egg (uniform), embroidery in proportion to rank. Piping is also often found, typically in contrast to the crown colour, which is usually white for navy, blue for air force, and green for army. The band is typically a dark, contrasting colour, often black, but may be patterned or striped. In the British Army, each regiment and corps has a different badge. In the United States Armed Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Visor
A sports visor, also called a sun visor or visor cap, is a type of headgear that consists of a bill to shade the eyes, attached to a headband used to secure it to the head. Some visors have a very large bill that can shade most of the entire face, while others have a bill similar to that of a baseball cap. Sports visors are often worn in hot sunny weather, where shading the eyes and face is desirable, but where trapped heat from a traditional baseball cap is not wanted.

Visard
A visard, also known as a vizard, is an oval mask of black velvet which was worn by travelling women in the early modern period 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 ''Carnival of Venice#Moretta/servetta muta, 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 Venetian mask, masked woman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
