Prescription safety spectacles by uvex

Polycarbonate (PC)

• Organic material with very high tensile strength
• Only limited chemical resistance
• Mechanical strength, class “F” (45 m/sec)
• PC+ – polycarbonate lens that is thicker in the middle, especially for uvex RX goggles

Trivex™

• Organic material with high tensile strength
• Lightweight, also suitable for high prescriptions
• Very good optical image reproduction properties even on high prescriptions
• Very high resistance to cleaning solutions, oils, cosmetics
• Good scratch resistance
• Best all-round lens material
• Mechanical strength, class “F” (45 m/sec)

CR39

• Also known as: plastic
• Not suitable for safety spectacles unless modified, as the tensile strength is otherwise too low. The middle of the lens must be thicker in order to meet the requirements for tensile strength.
• Organic, lightweight material
• Very good optical image reproduction properties even on high prescriptions
• Suitable for working with chemicals and paint
• Good scratch resistance thanks to hard coating (optional)
• Mechanical strength, class “S” (ball drop test)

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
