Eye protection
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.
The human eye is sensitive to intense light because it damages the retina and can even blind the individual. There are many different types of eye protection against light suited for different applications. The most common forms of eye protection against light are sunglasses. These primarily protect against UV light from the sun and help increase visibility in bright conditions. They often tend to be fashionable as well as practical.
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. In some applications, regular eye wear, if manufactured from high-impact materials, can be worn with removable side shields. Oversized spectacles are also manufactured, designed to sit over the users normal eye wear.
Goggles - Goggles are forms of protective eyewear that enclose the eye area in order to prevent particulates, infectious fluids, or chemicals from striking the eyes. Goggles come in two styles, eyecup goggles, and cover goggles. Eyecup goggles completely cover the eye socket to give all-round protection. They have adjustable or elasticized headbands and often are equipped with ventilation ports to allow air in and prevent fogging
Welding helmets & Shields - A welding helmet is a type of headgear used when performing certain types of welding to protect the eyes, face and neck from flash burn, ultraviolet light, sparks, infrared light, and heat. A welding hand shield is a metal plate containing the same protective lens as a welding helmet with a handle on the bottom, intended to be held up in front of the face while working.
Hoods - Hoods (or non-rigid helmets) come with impact-resistant windows usually made of plastic or similar material. An air-supply system may also be incorporated. Hoods are made of non-rigid material for use in confined spaces and of collapsible construction for convenience in carrying and storing
Face shields - A face shield is a device used to protect wearer's entire face (or part of it) from hazards such as impact, splash, heat, or glare. With face shields, as with welding helmets and hand shields, the user is continually lifting and lowering the visor. To protect the eyes when the visor is lifted, spectacles should be worn underneath.
Respirator face pieces - A respirator is a device designed to protect the wearer from inhaling particulate matter, including airborne microorganisms, fumes, vapours and gases.
