Eye protection must be suitable for the conditions it is used in. During winter, safety eyewear must offer reliable performance at low temperatures, adapt to changing light levels, and fit correctly alongside other PPE and clothing layers. Selecting the right eyewear ensures workers remain protected without introducing unnecessary risk.
Impact protection at low temperatures
The EN 166 standard includes optional testing for impact performance in extreme temperatures. For cold conditions, eyewear is tested after being conditioned for one hour at -5°C. Products that pass this test are marked with a ‘T’ after the impact rating on both the lens and frame.
For example:
A goggle rated BT provides medium energy (B) impact protection at low temperatures (T).
JSP’s range of spectacles, overspectacles, and goggles includes models that meet this standard. The JSP Thermex™ goggle is one such product, offering BT protection and additional testing at -40°C for extreme cold conditions.
Visibility and optical radiation
Winter brings reduced daylight hours and lower visibility. Safety eyewear with high optical clarity and good light transmission helps wearers maintain clear vision in darker conditions.
Despite lower sun intensity, UV exposure and glare risks still exist in winter—especially due to reflection from ice and snow. Choose lenses with UV and sunglare filtering to protect the eyes and support visibility. JSP offers multiple lens tints suitable for winter use, including:
Clear
Smoke
Indoor/outdoor
Polarised options
Anti-mist performance
Cold conditions increase the risk of lens fogging, which can obscure vision and increase the chance of accidents. Eye protection marked ‘N’ meets anti-mist performance standards. Products with both anti-mist and anti-scratch coatings are also marked ‘KN’.
The JSP Thermex™ goggle includes dual lenses with advanced fog resistance:
Inner lens marked N for anti-mist performance.
Outer lens marked KN, combining anti-scratch and anti-mist protection.
A moisture control patch helps regulate pressure and reduce fogging.
Tested for reliable vision down to -40°C.
Other JSP goggles and safety spectacles also offer anti-mist coatings to suit cold environments.
Fit and compatibility with winter clothing
Extra clothing layers like hats, balaclavas, and headwarmers can interfere with the fit of spectacles and goggles. Poor fit can reduce impact protection, affect lens clarity, and increase fogging.
Make sure:
Eyewear fits properly alongside cold-weather accessories.
Adjustable options are selected to ensure a secure and safe fit.
Equipment is designed to be compatible and worn together without compromise.
JSP’s adjustable eyewear ensures compatibility with a range of headwear and other PPE within the range of products of JSP. The JSP-GO™ platform includes fitting guides and videos to help users get the best fit.
Summary of key points:
Look for ‘T’-marked eyewear for impact protection in low temperatures.
Use high light transmission lenses to maintain visibility in low-light conditions.
Select lenses with UV and sunglare protection to reduce glare from snow and ice.
Choose anti-mist (N) or anti-mist/anti-scratch (KN) marked eyewear for fog-free performance.
Ensure eyewear fits correctly with hats and winter PPE to maintain protection and comfort.
