Eye protection

Spectacles

Examples of different styles of Safety Glasses

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 mount insert frames to mount prescription corrective lenses for users with suboptimal vision. Such insert frames are mounted behind the protective lens. 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

Cover style safety 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. For example, swimming goggles to protect the eyes from salt or chlorine. Cover goggles are designed to be worn over eye wear. Like eyecup goggles, they have adjustable or elasticized headbands and are equipped with direct or indirect ventilation ports to allow air in and prevent fogging. While both models keep out large particles, indirect-vented goggles are better at keeping out liquids and dusts.

Welding helmets and 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

Sand Blasting in protective hood

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.

Use screen filters

Using special screen filters to the front of your device can reduce the amount of digital blue light emitted from your device. Now it is available on the market like – mobile screen protector, computer screen protector for reducing blue rays from electronic devices.^[1]

Flying objects

Flying particles, dust, and wind

Heat, sparks, and splash from molten materials

Acid splash; chemical burns

A large percentage of eye injuries are caused by direct contact with chemicals. These injuries often result from an inappropriate choice of personal protective equipment that allows a chemical substance to enter from around or under protective eye equipment. Serious and irreversible damage can occur when chemical substances contact the eyes in the form of splash, mists, vapors, or fumes. When working with or around chemicals, it is important to know the location of emergency eyewash stations and how to access them with restricted vision.^[2]

When fitted and worn correctly, goggles protect your eyes from hazardous substances. A face shield may be required in areas where workers are exposed to severe chemical hazards.^[2]

Personal protective equipment devices for chemical hazards:

• Safety goggles: Primary protectors intended to shield the eyes against liquid or chemical splash, irritating mists, vapors, and fumes.
• Face shields: Secondary protectors intended to protect the entire face against exposure to chemical hazards.^[2]

Abrasive blasting materials

Glare or stray light

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.

Injurious optical radiation (Moderate)

Laser protection eyewear will filter out a particular (or small range of) wavelength(s), customized to the laser being viewed. Laser protection eye wear is particularly important because of the extremely high intensity of laser light.

Injurious optical radiation (Severe)

Welding glass protects against glare and flying sparks. It is a more extreme implementation of the same idea as sunglasses, suited to the more intense light generated during welding. Arc welding goggles must be much darker than blowtorch goggles. Shades 12, 13, and 14 welding glass must be used to stare directly at the sun or a solar eclipse. These higher index shades are suitable for arc welding and therefore are suitable for solar viewing.^[3][4] Sunglasses will not provide sufficient protection.^[5]
