Grey frameless safety glasses cut sun glare and brightness for outdoor work while protecting the eyes from flying particles. The tinted polycarbonate lens wraps round the face with no frame around it, held in place by a soft TPE nose bridge and temple tips. They suit highways, groundworks and site work in bright, sunny conditions.
How a Grey Sun Glare Lens Stops Squinting on Bright Sites
Clear safety glasses let full sunlight through, so on a bright day workers squint against the glare. That leads to tired eyes, missed hazards, or ordinary sunglasses worn in place of rated eye protection. A grey 5-2.5 sun glare lens cuts the brightness while keeping the same EN 166 impact protection as a clear pair.
Key Features
- Grey sun glare filter lens: marked 5-2.5, it reduces brightness and glare on sunny days, so there is no need to swap to unrated sunglasses.
- Frameless wraparound lens: no rim at the edge of your view, so you can see plant and traffic moving beside you.
- UV and solar radiation protection: shields the eyes during long days working outdoors.
- FT impact rating: lens and frame are tested against low-energy impact at 55°C and -5°C, from hot summer sites to frosty mornings.
- Optical class 1: clear, undistorted vision through the tint for a full shift.
- Soft TPE nose bridge and temple tips: a secure, comfortable fit across a wide range of face sizes, metal free at just 26g.

Typical Users and Projects
Highways, groundworks and landscaping teams wear grey frameless safety glasses for outdoor work in bright sun. They suit daytime tasks where flying particles are a low-energy hazard and glare makes it hard to see, such as roadworks, site set-out and grounds maintenance. The frameless lens keeps side vision clear, which matters when working near moving plant and traffic.
Typical applications
- Setting out and supervising roadworks and traffic management in daylight.
- Working on groundworks, drainage and external works on sunny sites.
- Carrying out grounds maintenance and landscaping work on bright days.
- Fitting and maintaining street furniture and signage outdoors.
- Carrying out roofing and external building maintenance in direct sun.
- Inspecting utility and infrastructure assets outdoors.
How to use
Step 1: Check that the light is bright enough for a tinted lens. Use a clear lens indoors or in low light.
Step 2: Inspect the lens and frame for scratches, pits or damage before each use.
Step 3: Put the glasses on so the nose bridge sits on your nose and the temple tips rest behind your ears.
Step 4: Attach the neck cord so the glasses hang safely when you move indoors and take them off.
Step 5: After use, clean the lens and store the glasses out of direct sunlight.
Common mistakes
- Keeping the grey lens on when moving indoors or working on into dusk.
- Wearing them to drive, especially into tunnels where light drops suddenly.
- Treating the grey tint as welding protection, which it is not.
- Relying on them for grinding, where fragmenting wheels need higher-rated eye protection.
- Leaving them on a van dashboard in direct sunlight, against the manufacturer’s storage advice.
Safety
Under the Personal Protective Equipment at Work Regulations 1992, employers must provide suitable eye protection where a risk assessment shows it is needed. The tinted lens reduces the light reaching your eyes, so do not wear it in low light, at night or when driving into tunnels. The impact rating covers low-energy impact only, not fragmenting grinding wheels, high-speed projectiles, explosive devices or molten metal. Seek medical advice if the materials cause a skin reaction.
Maintenance
Rinse the lens with water and pat it dry with a lint-free cloth. A mild detergent mixed with water disinfects the glasses. Keep them in a microfibre pouch or case, out of direct sunlight and away from abrasive chemicals. Once the lens is scratched, pitted or damaged, replace the whole pair, as no spare lenses or parts are available.
Frequently Asked Questions
Q: Are grey safety glasses suitable for working in bright sunlight?
A: The grey lens is a sun glare filter marked 5-2.5 under EN 172, made for outdoor work in bright conditions. It reduces brightness and glare and protects against UV and solar radiation. It also keeps the same EN 166 impact rating as a clear pair.
Q: What does 5-2.5 1 FT mean on tinted safety glasses?
A: The 5 means a sun glare filter without an infrared specification, and 2.5 is the shade number. The 1 is optical class 1, the best optical class. FT is the impact rating: F for low-energy impact, with T confirming it was tested at -5°C and 55°C.
Q: Are these grey safety glasses impact rated?
A: Both lens and frame carry the EN 166 F rating for low-energy impact, tested with a 6mm steel ball at 45 metres per second. The added T means the rating also holds in extreme heat and cold. Tasks with medium or high-energy impact need eye protection marked B or A.
Q: What should I not use grey safety glasses for?
A: Do not wear them in low light, at night or for driving, as the tint reduces what you can see. The 5-2.5 lens is not a welding filter. They are also not rated for fragmenting grinding wheels, high-speed projectiles, molten metal, liquid droplets, dust or gas.
Q: Grey or clear lens: which should I buy?
A: Pick grey for daytime outdoor work where glare is a problem, such as highways and groundworks. Pick clear for indoor work, low light and tasks that need true colour vision. Many teams keep both, as the frameless fit and impact rating are the same.
Q: Can I wear these when moving between indoors and outdoors?
A: The grey tint is made for bright outdoor light, so it will reduce visibility indoors. Take them off, let them hang on the neck cord and switch to a clear pair inside. For work that moves in and out often, ask our team about a lighter indoor/outdoor lens.
Q: Are the lenses anti-fog or anti-scratch?
A: The lens marking does not include the EN 166 N (anti-fog) or K (anti-scratch) symbol, so we do not claim either. A factory coating is applied, but it is not rated under EN 166. For misting conditions, look for eye protection marked N or KN.
Q: How do I clean and store tinted safety glasses?
A: Rinse with water, pat dry with a lint-free cloth and disinfect with a mild detergent solution when needed. Store them out of direct sunlight, ideally in a pouch or case. With correct care they should give adequate protection for 2 years. Replace them sooner if the lens is scratched or pitted.
Q: Can our buyers order safety glasses through a procurement portal?
A: EDGE is a free procurement portal with user access control, per-project budgets and delivery addresses, and Punchout, EDI or API integration. Site teams can also order through the EDGE App, with live pricing and stock on over 8,000 products. Everything is tracked in one place with CMT Group.
Q: What do other customers say about ordering PPE from you?
A: We are rated Excellent on Trustpilot and hold 4 stars from over 400 verified reviews on Reviews.io. Trade customers across the UK have relied on us for site equipment and PPE since 2010.
