Clear frameless safety glasses protect the eyes from flying particles and UV radiation while keeping colours true. The single polycarbonate lens wraps round the face with no frame around it, and a soft TPE nose bridge and temple tips hold it in place. They suit site, workshop and maintenance work indoors and in low light.
How a Frameless Wraparound Lens Keeps Side Vision Clear
Standard framed safety glasses put a rim across the edge of your view. On site, that blind edge leads people to lift their glasses or take them off to check around them, leaving their eyes exposed. A frameless wraparound lens has no rim in the line of sight, so side vision stays clear and the glasses stay on.
Key Features
- Frameless wraparound lens: no rim in your line of sight, for a wider side view while you work.
- Clear UV filter lens: filters 99% of harmful UV up to 380nm while keeping colours true, so cable cores and markings are easy to read.
- FT impact rating: lens and frame are tested against low-energy impact at -5°C and 55°C, so protection holds in cold and hot conditions.
- Optical class 1: the highest optical class under EN 166, suitable for wearing through a full shift.
- Soft TPE nose bridge and temple tips: grip without pressure points and give a secure fit across a wide range of face sizes.
- 100% metal free at 26g: no metal hinges or screws, and light enough for all-day wear.

Typical Users and Projects
Electricians, maintenance engineers and vehicle technicians wear clear frameless safety glasses for routine work indoors, in workshops and on construction sites. They suit tasks where flying particles are a low-energy hazard and colours need to stay true, such as wiring and assembly. The light frameless design suits wearers who keep their eye protection on for a full shift.
Typical applications
- Drilling, cutting cable and fitting accessories during electrical installation and maintenance.
- Assembling components and products on manufacturing lines.
- Carrying out vehicle repairs and servicing in workshops.
- Working on joinery, woodwork and light fabrication tasks.
- Carrying out planned maintenance in offices, schools and housing.
- Working on highways and infrastructure projects in low light or overcast conditions.
How to use
Step 1: Check that the markings match the hazards in your risk assessment.
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 to the temple tips so the glasses hang safely when you take them off.
Step 5: After use, clean the lens and store the glasses in a dry, clean place.
Common mistakes
- Wearing the clear lens for bright outdoor work, where a sun glare lens is needed.
- Relying on low-energy impact protection for grinding, where fragmenting wheels need higher-rated eye protection.
- Rubbing the lens dry with a rough cloth, which scratches it.
- Keeping a scratched or pitted pair in use, which lowers impact resistance and optical quality.
- Wearing them over prescription glasses, which can transmit an impact to the wearer.
Safety
Under the Personal Protective Equipment at Work Regulations 1992, employers must provide suitable eye protection where a risk assessment shows it is needed. These glasses are rated for low-energy impact only. They do not protect against fragmenting grinding wheels, high-speed projectiles, explosive devices or molten metal. The materials may cause a skin reaction in sensitive wearers, so seek medical advice if a reaction appears.
Maintenance
Clean the glasses with water and pat the lens dry with a lint-free cloth. Disinfect them with a mild detergent mixed with water. Store them dry, away from direct sunlight and abrasive chemicals, ideally in a microfibre pouch or case. Replace the whole pair once the lens is scratched, pitted or damaged, as there are no spare lenses or parts.
Frequently Asked Questions
Q: Do clear frameless safety glasses protect against UV?
A: The clear lens is a UV filter marked 2C-1.2 under EN 170. It filters 99% of harmful UV radiation up to 380nm while keeping good colour recognition. It does not protect against sun glare, so choose a grey sun glare lens for bright outdoor work.
Q: What does 2C-1.2 1 FT mean on safety glasses?
A: 2C-1.2 is the filter marking: 2C means a UV filter with good colour recognition, and 1.2 is the shade number. The 1 is optical class 1, the highest optical class, suitable for continuous wear. FT is the impact rating: F means low-energy impact, and T means it was also tested at extremes of temperature, -5°C and 55°C.
Q: How much impact protection do these safety glasses give?
A: The lens and frame are both marked F, the EN 166 rating for low-energy impact. In the EN 166 test, that is a 6mm steel ball at 45 metres per second. The T after the F confirms the rating holds at -5°C and 55°C. For higher-energy hazards, use eye protection marked B or A.
Q: What are these safety glasses not suitable for?
A: They are not suitable for fragmenting grinding wheels, high-speed projectiles, explosive devices, molten metal or welding. They carry no EN 166 field of use marking for liquid droplets, dust or gas, so use goggles marked for those hazards. The clear lens also does not cut sun glare.
Q: Should I choose the clear or grey lens?
A: Choose the clear lens for indoor work, low light and tasks where you need to see true colours, such as wiring. Choose the grey lens for bright outdoor work, as it is a sun glare filter marked 5-2.5. Both have the same frameless wraparound fit and FT impact rating.
Q: Do these glasses have an anti-fog coating?
A: The lens has a factory coating, but its marking does not include the EN 166 N symbol for anti-fog or K for anti-scratch. We do not claim either property for this lens. If misting is a known problem on your site, choose eye protection marked N or KN.
Q: Can I wear these safety glasses over prescription glasses?
A: These are not over-spectacles, so they are not designed to fit over prescription glasses. The manufacturer warns that prescription glasses worn under eye protection can transmit an impact to the wearer. Use over-spectacles designed for the purpose, or prescription safety eyewear.
Q: How long do safety glasses last and when should I replace them?
A: With normal use and correct storage, the manufacturer expects these glasses to give adequate protection for 2 years. Inspect them often. Replace the whole pair as soon as the lens is scratched, pitted or damaged, because this reduces impact resistance and optical quality. There are no replacement lenses or spare parts.
Q: Can we order safety glasses for a whole site team at once?
A: Large PPE orders travel on our own delivery fleet, which covers over 95% of the UK mainland, not a third-party courier. Every delivery comes with live tracking, live ETAs and proof of delivery with location photos. We hold large stocks of PPE to supply full team orders from CMT Group.
Q: How do we know the eye protection you supply meets UK standards?
A: We are a BSIF Registered Safety Supplier, and our dedicated compliance team checks products against the relevant UK regulations and standards. This pair carries EN 166 and UKCA markings on the frame. We also hold ISO 9001:2015 quality accreditation.
