Portwest Air Safety Glasses

Barely There. Brilliantly Protected.

When it comes to safety eyewear, weight is one of the biggest barriers to consistent, all-day wear. The Portwest PR12 Air Safety Glasses eliminate that barrier entirely. At just 12.5 grams, the PR12 is one of the lightest pairs of safety glasses in the world — so featherlight that wearers can genuinely forget they have them on, while remaining fully protected throughout even the longest shifts.

Don't let the minimal weight fool you. The PR12 is CE certified to EN 166, EN 170, and EN 172, meeting the recognised European standards for occupational eye protection, UV filtration, and solar glare protection. This is serious, certified PPE — it just happens to weigh next to nothing.

Engineered for All-Day Comfort

The PR12 has been purpose-built around one core principle: that safety glasses should never be a burden to wear. Every design decision — from the ultra-slim profile to the carefully considered materials — has been made with extended, fatigue-free wear in mind.

The single panoramic polycarbonate lens delivers a wide, unobstructed field of vision without the bulk or weight of a larger frame, keeping the overall footprint of the glasses compact and unobtrusive. The moulded universal nose piece distributes what little weight there is evenly across the nose bridge, preventing the pressure points and discomfort associated with heavier eyewear during long periods of use.

The slim, streamlined side arms are a particularly thoughtful feature for workers operating in noisy environments. Thicker arms on conventional safety glasses can interfere with the seal of ear defenders and earmuffs — a common frustration on site. The PR12's slim arm profile minimises this interference, making it one of the most compatible safety spectacles available for workers who regularly use hearing protection alongside eye protection.

The Right Fit for Smaller Face Shapes

Standard-sized safety glasses are designed around an average face shape — which means a significant portion of the workforce ends up wearing eyewear that doesn't quite fit correctly. Loose-fitting glasses shift out of position, create gaps in protection, and become an active distraction during work.

The compact design of the PR12 makes it particularly well suited to workers with smaller or narrower face shapes, ensuring a proper, secure fit that stays in place throughout the working day. Combined with the universal nose piece, the PR12 offers a fit that feels custom without requiring adjustment.

Advanced Lens Performance

The PR12 lens is fully treated with a suite of performance coatings to ensure clarity and longevity in demanding workplace conditions:

• Anti-fog coating prevents the lens from misting during temperature changes or high-intensity physical work, keeping vision consistently clear without interruption.
• Anti-scratch coating protects the polycarbonate lens from the everyday abrasions of site work, maintaining optical clarity and extending the working life of the glasses.
• UV protection in line with EN 170 (2C-1.2) filters harmful ultraviolet radiation, protecting eyes during outdoor work or in environments with UV-emitting equipment or lighting.

The panoramic single-lens design also supports a wide, distortion-free field of view — ideal for tasks that require strong situational awareness or close visual attention.

Solar Protection for Outdoor Workers

Certified to EN 172 (5-3.1), the PR12 provides meaningful protection against sun glare, making it a practical choice for workers who spend time outdoors or move regularly between indoor and outdoor environments. Whether on a construction site, in open-air manufacturing, or carrying out external maintenance, the PR12 handles changing light conditions with ease.

100% Metal Free

The PR12 is constructed entirely from polycarbonate with no metal components whatsoever, making it hypoallergenic and suitable for workers with metal sensitivities. It is also appropriate for environments where metal contamination must be controlled, such as food processing, pharmaceutical production, or cleanroom settings.

Practical for Retail & Vending

Each pair of PR12 Air Safety Glasses is supplied in a retail-ready presentation bag, making them an excellent choice for safety equipment retailers and trade counters where clean, professional presentation matters. They are also individually packed for vending machine compatibility, ensuring workers in larger facilities can access fresh, hygienically packaged PPE on demand, around the clock.
