Log in to access trade discountsThe armourU K2 Clear Lens is a 25g all-environment safety spectacle engineered for UK professionals who require certified eye protection across a broad range of indoor and outdoor tasks. Its defining feature for many buyers is the 100% metal-free frameless screwless construction, which makes it the correct specification for electrical contractors working near live systems, food processing operatives where metal contamination is a regulatory concern and security environments with metal-detection entry requirements.
The clear polycarbonate lens carries anti-fog and anti-scratch coatings on both surfaces, maintaining optical clarity when moving between temperature zones or working in dusty conditions. At 25g, it is substantially lighter than comparable safety spectacles, and the nonslip arms with clear TPE nose rest ensure a stable, pressure-free fit during full-day wear. The optical Class 1 lens meets the distortion standard for all-day use and close-precision tasks.
Certified to EN166 FTKN and EN170 2C-1.2, meeting UK Regulation 2016/425 on PPE. Maximum product life is two years. Supplied with a recycled polyester pouch made from two 1-litre plastic water bottles and a recycled paper box, supporting site-level ESG and ThinkGreen reporting.
✓ 100% metal-free frameless screwless construction qualifies for electrical environments, food manufacturing and metal-detection security checkpoints
✓ F-rated low energy impact protection at extreme temperatures confirmed under EN166 FT marking for all-weather site use
✓ Anti-fog coating on both lens surfaces maintains clear vision in humid conditions, cold stores and temperature-variable environments
✓ Anti-scratch coating on both lens surfaces extends service life in dusty construction and manufacturing environments
✓ Optical Class 1 clear polycarbonate lens delivers undistorted full-field vision for precision tasks and driving
✓ 25g featherweight frame with nonslip arms and TPE nose rest eliminates the pressure fatigue that drives PPE non-compliance
✓ Recycled polyester pouch from two 1-litre plastic water bottles supports site sustainability and CMT ThinkGreen procurement reporting

Usage Guide:
Before Use
Inspect lenses for cracks, scratches, pitting or coating damage before each use and discard any spectacle showing these defects. Confirm the task hazard level is within scope: this is an F-rated low energy impact spectacle. For high-energy impact tasks such as grinding or chiselling, a higher-rated product is required. Do not use near welding operations, molten metal casting, UV curing environments or hazardous UV or IR radiation sources. Do not wear over prescription frames as impact may transmit to the prescription frame. Check for allergic reaction to materials on first use and cease use if any reaction occurs.
During Use
The clear lens provides full light transmission and is designed for indoor, low-light and general outdoor use. Do not use as a sun glare filter in bright outdoor conditions; use the smoke lens variant AEYK2S instead. The anti-fog coating reduces but does not eliminate condensation under extreme temperature differentials. Do not wipe lenses with abrasive materials. Check regularly for visible scratching, pitting or crazing and replace immediately if found.
After Use
Clean with soap and warm water or a soft non-abrasive cloth. Do not use solvents, abrasive cloths or paper towels. Store in the supplied recycled polyester pouch away from solvents, solvent vapours and corrosive materials. Store above 5°C and below 40°C at no more than 90% relative humidity. No parts are replaceable or interchangeable; if any component is unfit for use, discard the entire product. Maximum product life is two years.
Why does metal-free construction matter for electrical work and food manufacturing?
In electrical environments, metal components on eyewear present a conductivity risk if the frame contacts a live system. In food manufacturing and processing, metal contamination is a regulatory concern under food safety legislation, and metal-free PPE is frequently a site specification requirement. The K2 Clear contains no metal in any component including frame, screws or nose rest, making it compliant for both applications without requiring a separate specialist product.
What does EN166 FTKN mean for an indoor clear lens spectacle?
F confirms low energy impact resistance,
T confirms the protection is maintained at extreme temperatures,
K confirms the anti-scratch coating
and N confirms the anti-mist coating all meet EN166 requirements.
For indoor environments where temperature variation, humidity and dust are common, the TKN combination is particularly relevant as it confirms the spectacle performs under the conditions found in cold stores, food processing facilities, construction interiors and humid workshops rather than only in controlled ambient conditions.
What is the difference between this product and the K2 Smoke lens?
Both share the same 25g metal-free frameless construction, EN166 FTKN rating, dual-sided anti-fog and anti-scratch coatings and TPE nose rest. The clear lens variant (AEYK2C) carries an EN170 2C-1.2 UV filter and is designed for indoor, low-light and general outdoor use where full light transmission is needed. The smoke lens variant (AEYK2S) carries an EN172 5-3.1 sun glare filter and is designed for bright outdoor conditions, plant operation and driving in high-glare environments. Specifying both variants covers a full site workforce regardless of task location.
Is this spectacle suitable for all-day wear in food manufacturing environments?
Yes. The 100% metal-free construction satisfies food site PPE specifications. At 25g, the lightweight frame prevents the nose and ear discomfort that causes operatives to remove eyewear during long production shifts, which is one of the most common compliance failures in food manufacturing environments. The dual-sided anti-fog coating maintains clear vision in the temperature-variable conditions typical of food processing facilities, and the optical Class 1 lens meets the distortion standard for sustained precision work.
What is the maximum service life and when should these be replaced?
Maximum product life is two years from manufacture. Replace immediately if any scratching, pitting, crazing or visible lens damage is present regardless of age, as lens damage significantly reduces impact protection even if the spectacle appears functional. No parts are replaceable or interchangeable; discard the entire product if any component fails.
What is CMT ThinkGreen and does this product qualify?
CMT ThinkGreen is CMT Group's sustainability programme supporting construction and manufacturing operations in reducing their procurement environmental footprint. The K2 Clear qualifies through its recycled polyester pouch, manufactured from two 1-litre plastic water bottles, and its recycled paper box. For procurement teams with ISO 14001, net-zero supply chain commitments or ESG reporting requirements, specifying ThinkGreen-aligned products provides measurable, documentable contributions to sustainability targets without compromising certified safety performance.
Why buy metal-free safety eyewear from CMT Group?
Electrical contractors and food manufacturers procuring metal-free PPE at volume need a supplier who stocks correctly specified products consistently, not a generalist catalogue where metal-free compliance is an afterthought. CMT Group's armourU eyewear range is selected for the UK trade market and held in stock for next-day fulfilment. For operations managing PPE compliance across multiple sites or large workforces, the EDGE portal allows procurement managers to lock approved metal-free products to specific sites, preventing operatives from substituting non-compliant alternatives and giving H&S officers full spend visibility across every location.
Founded in 2010, CMT Group is now the UK's largest independent site equipment supplier and holds BSIF Registered Safety Supplier status, meaning every product on the platform has been verified against genuine certified safety standards. For electrical and food industry procurement teams where product compliance documentation is audited regularly, BSIF membership provides an additional layer of assurance that the eyewear on your specification sheet is the eyewear your operatives are actually wearing.
