Veiligheidsbrillen op sterkte van uvex

Polycarbonaat (PC)

• Organisch materiaal met zeer hoge treksterkte
• Slechts beperkte chemische weerstand
• Mechanische sterkte, klasse "F" (45 m/sec)
• PC+ - polycarbonaat lens die dikker is in het midden, speciaal voor uvex RX brillen

Trivex™

• Organisch materiaal met hoge treksterkte
• Lichtgewicht, ook geschikt voor lenzen met hoge sterkte
• Zeer goede optische beeldweergave, zelfs bij lenzen met hoge sterkte
• Zeer hoge weerstand tegen schoonmaakmiddelen, oliën, cosmetica
• Goede krasbestendigheid
• Beste all-round lensmateriaal
• Mechanische sterkte, klasse "F" (45 m/s)

CR39

• Ook bekend als: plastic
• Niet geschikt voor veiligheidsbrillen, tenzij aangepast, omdat de treksterkte anders te laag is. Het midden van het brillenglas moet dikker zijn om aan de eisen voor treksterkte te voldoen.
• Organisch, lichtgewicht materiaal
• Zeer goede optische beeldweergave, zelfs bij lenzen met hoge sterkte
• Geschikt voor het werken met chemicaliën en verf
• Goede krasbestendigheid dankzij harde coating (optioneel)
• Mechanische sterkte, klasse "S" (kogeldalingstest)

HI (high index), organic lens materials with high refractive index

• Organic-material lenses with a refractive index of 1.6 or 1.67 are optically more effective (than CR 39)
• With less material and less curved surfaces, the lens has the required optical effect
• The lens is thinner and looks more attractive
• Recommended for prescriptions > +/-4.0 dpt.: HI 1.6
• Recommended for prescriptions > +/-6.0 dpt.: HI 1.67
• Mechanical strength, class “S” (ball drop test)

Hard glass

• Also known as: crown glass, silicate, mineral glass, glass
• Not suitable for safety spectacles unless modified, as the tensile strength is otherwise too low
• Tensile strength is increased by thermal or chemical curing
• Mechanical strength, class “S” (ball drop test) extremely scratch-resistant surface, suitable for working with chemicals and paint
• Heavy, not suitable for prescriptions higher than +/-4.0 dpt.
• Protects against flying sparks during welding and grinding work
• Protects against molten metal splashes and hot solid projections

Tinted lenses provide effective protection against glare in areas with high light intensity (for example, sunlight)

 

Constant tinting:

• Available in brown or grey
• Tinting levels: 15%, 25%, 65%, 75%

Variable tinting – Variomatic™

• Lenses tint automatically, depending on the intensity of the UV radiation and temperature 
• Tinting of approx. 8% to 80% in brown
• Available on polycarbonate and Trivex™ prescription safety lenses

 

 

A special absorber has been added to the lens material that completely filters out UV rays and reduces the blue light content.

• The lenses absorb UV radiation up to 400 nm at 100%, filter short-wave blue light until 410 nm almost completely and reduce the range from 410 nm to 420 nm around 86%.
• uvex UV blue protect lenses enhance contrast and effectively prevent signs of fatigue and age-related macular degeneration (AMD)
• UV blue protect is optionally available for polycarbonate (PC) lenses and HI 1.67
• the mechanical strength of the lenses is guaranteed — clear lenses with UV blue protect are marked 2C-1.2 according to EN 170

Didymium

• Special filter with high absorption at 589 nm, resulting in characteristic violet colour
• The 'bright yellow sodium flare' is filtered out
• Lightweight polycarbonate filter with mechanical strength 'F' (45 m/s)
• Level of protection 2-2 in accordance with EN 17
• Marking: 2-2 W 1 F CE
• Note: Didymium lenses do not provide increased protec-tion against infrared radiation (IR)

Areas of application: Glass production, glass processing, e.g. glass blowing

 

X-ray protection

• Mineral lenses that provide protection against X-rays
• The lead equivalent of the protective lenses is 0.75
• The lead content in the lenses gives them their character-istic grey colour (approx. 10% colouring)
• Marking: Pbeq 0.75
• Note: Protective X-ray lenses are not tested and marked in accordance with EN 166

Areas of application: e.g. crack and material testing

 

Welding protection

• Welding protection level 5 in accordance with EN 169
• Grey-tinted polycarbonate filters for reliable protection against UV and infrared radiation with mechanical strength 'F' (45 m/s)
• Perfect colour perception during the welding process
• Marking: 5 W 1 FTK CE
• Note: Welding protection lenses do not provide sufficient protection against laser beams!

Areas of application: Autogenous welding

CBR65

• Contrast enhancement – For better contrast and comforta-ble vision, even in diffused light
• Blue light reduction – Blue light is reduced by up to 50% in extremely bright workplaces
• Relaxed vision – Reduced eye fatigue, even during longer periods of use
• 65% transmission – Slight tint for optimal protection against glare for high visual standards even in extremely bright, artificial light as well as natural light
• Lightweight polycarbonate filter with mechanical strength 'F' (45 m/s)
• Marking: 5-1.4 W 1 FK CE

Areas of application: Workplaces with high visual standards in very bright artifi-cial light or natural light

 

Polarisation filter

• Polarising filters only let in radiation from one vibration direction — scattered radiation (e.g. reflection on the surface of water) is suppressed
• Lightweight polycarbonate filter with mechanical strength 'F' (45 m/s)
• Marking: 5-3.1 W 1 F CE

Areas of application: Particularly suitable for workplaces with a high risk of glare and/or highly reflective surfaces, offshore, maritime environment, construction industry
