Legal note
uvex cannot be held liable for any damage resulting fromthe advice given in this booklet. This booklet must not beconsidered a substitute for either a risk assessment orpurchase advice.
Definition of eye protection
Safety eyewear protects the eyes against harmfulinfluences such as intense light, UV radiation, liquid splash,dust, splinters or weather effects. Eye protection typicallytakes the form of single-or twin-lensed glasses whichare held in place by side arms that go over the ears orgoggles that provide additional protection against highenergy impacts, liquid splash or dust due to the all roundseal. These are held in place by an adjustable headband.
Please note that selecting and using appropriate eyeprotection requires a detailed risk analysis of the work-place and the hazards present. Legal regulations andprovisions must be also be observed.

Types of workplace hazards
When identifying hazards it is important to take intoaccount and distinguish between the type of hazard, thescope, duration, probability and the severity of the incidenton the individual.
Potential hazards include mechanical, optical, liquid splash,thermal, biological and electrical hazards. In many cases,several hazards may be present at any one time.
Welding, for example, involves optical, mechanical andthermal hazards. Applications in which liquids or gasescan escape under high pressure involve mechanical aswell as chemical or thermal hazards.
9
Mechanical hazards: Foreign objects such as dust andsolids (chips or grains) that can get into the eye.
Optical hazards: Ultraviolet, visible and infrared radiationin the form of ultraviolet glare, flash burns or thermalhazards.
Chemical hazards: Solid, liquid or gaseous substancessuch as vapour, mist and smoke as well as acids or lyes.
Thermal hazards: Heat that is transferred through solidsor liquids via gases or infrared radiation as well as extremecold.
Biological hazards: Bacteria, viruses and spores thatcan enter the body through the eyes can cause infections.
Electrical hazards: Electric arcs caused by short-circuitswhen working in electrical power distribution plants, forexample.

Optical radiation is divided into three areas:
• UV radiation 100 nm – 380 nm (UV = ultraviolet,short-wave, invisible and high-energy)
• Solarium• Sun• Fluorescence
• VIS radiation 380 nm – 780 nm (VIS = visible)• Prismatic colours
• IR radiation 780 nm – 1 mm (IR = infrared, long-wave,invisible)
• Thermal radiation• Heat lamps• Welding

Optical clarity and useful life
Optical class 1 lenses are particularly suitable when ahigh level of visual performance is required while protec-ting the human eye against damage in the form ofdefective vision, even when worn for prolonged periodsof time.
All uvex eyewear conforms to optical class 1.
When stored correctly and without use, the maximumlifetime of a safety eyewear product is 6 years. Dependingon the intensity of use and wear caused by externalinfluences, the maximum life of a product is 2 years.If protective eyewear has been scratched or otherwisedamaged it must be replaced.

Cleaning
Cleaning recommendations for protective eyewear
• Rinse off coarse dirt under flowing water, when possible
• Clean the lenses using uvex cleaning spray and tissues,or uvex lens cleaning towelettes
• Commercially available disinfectants can be used byspraying or wiping; do not immerse eyewear indisinfectant
• Store eyewear in a case when not in use

Types of protective eyewear
Safety spectaclesClassic style safety glassesusually come in the form ofsingle- or twin-lensedglasses. Well fitting spectacleswill ensure a secure andcomfortable fit and protectagainst common hazards.
OverspecsProtective eyewear that can beworn over prescription glassesand are often worn by sitevisitors. Ideal for short-term use.
GogglesProtective eyewear with anallround seal and headband forprotection against increasedmechanical and liquid splashhazards. Depending on theshape, some can be worn overprescription glasses.
VisorCovers the entire face, speciallydesigned to protect againstmechanical and liquid splashhazards. Some designs allowgoggles to be worn under avisor which can increase theprotection against liquid splash.

uvex UV protection
Polycarbonate which is used to manufacture uvex safetylenses absorb 100% of UV radiation up to 400 nm.All uvex lenses offer 100% UVA, UVB and UVC protection.

uvex lens coating technology
Fogged up and scratched lenses are often the mainreasons that safety eyewear is taken off or not worn.High quality, effective and durable lens coatings raise thevalue and 'wearability' of eyewear for the wearer.
uvex has developed specially formulated scratch-resistantand anti-fog coatings that are permanent for the lifetimeof the product. No matter how many times the productgets cleaned, the eyewear will remain fog free.
The unique uvex lens coating process enables differentcoatings to be applied to the inside and outside of thelens. Unlike conventional dip coating processes used byother manufacturers (applying one coating to both sides),the uvex process allows each coating to performindependently and therefore delivers a more effectiveand visibly noticeable result.

Different workplaces require different lens coatingsdepending on the level of dirt, heat and humidity. uvexhas developed a range of coatings with these variablesin mind. For example, a very humid environment such asa foundry will require an anti-fog coating on both sidesof the lens to ensure clear vision.
uvex's most popular lens coating, uvex supravisionexcellence is ideal for those that require anti-fog on theinside of the lens due to body heat, and a scratch resistantcoating on the outside to help with external factors thatmay damage the lens. A scratch resistant coating helpsprolong the life of the product.

Choosing the right glasses
As well as the protection level offered, design (both shapeand style) coupled with comfort all play an important rolewhen choosing the right eye protection. Not all safetyeyewear is the same and no two people are the same aspeople's faces vary considerably and is why the size andshape is important to ensuring the best fit and level ofprotection. Different models are offered which take intoaccount different head and facial features. Trying ondifferent styles of safety eyewear to ensure a closecomfortable fit that meet the identified protection levelfor the workplace risk is paramount.
It is important to consider prescription wearers whenselecting safety eyewear. For example, uvex offersoverspecs that can be worn over prescriptionglasses for short periods. Alternatively, uvex offerscustomised protective eyewear, our prescription safetyspectacles which offer considerably higher levels ofcomfort.
