Portwest Extra OTG Safety Glasses

Professional eye protection designed around the way you already see. The Portwest PR03 Extra OTG Safety Glasses are engineered specifically for prescription eyewear users — delivering certified occupational eye protection that fits comfortably and securely over virtually any pair of glasses, eliminating the need for prescription safety eyewear or the inconvenience of contact lenses on site.

The extra-wide frame design accommodates the full range of prescription glasses styles and sizes, while inclinable side arms allow the fit to be fine-tuned to the individual wearer for a secure, snug result that doesn't shift during active work. Soft rubber temple tips grip the head without pressure or slipping, and the moulded nose piece distributes weight evenly for a universal, comfortable fit across extended periods of wear. The stylish dual colour side arms give the PR03 a contemporary appearance that sits comfortably alongside modern workplace dress codes.

Protection is delivered through a single wrap-around polycarbonate lens that provides exceptional coverage of the eye area from the front and sides — resisting the dust, debris, and impact hazards present in industrial, construction, manufacturing, and laboratory environments. An anti-scratch coating extends the working life of the lens under demanding conditions, while the anti-fog coating maintains clear, unobstructed vision during temperature changes, physical exertion, and humid working environments where fogging is a persistent practical challenge for over-glasses wearers.

UV protection is integrated throughout the lens, guarding against harmful ultraviolet radiation during outdoor working — a consideration for construction, utilities, landscaping, and agricultural professionals who spend extended periods working in direct sunlight. The PR03 is 100% metal free throughout, making it suitable for use in environments where non-conductive PPE is specified.

Certified to EN 166, EN 170, and EN 172, and supplied in a retail bag with Euro slot for point-of-sale display. Individually packed for vending machine compatibility.

What does OTG mean in safety glasses? OTG stands for Over-The-Glasses. OTG safety glasses are specifically designed with a wider, deeper frame profile that fits over the top of prescription eyewear, allowing people who wear corrective glasses to benefit from certified eye protection without needing to remove their glasses, wear contact lenses, or invest in custom prescription safety eyewear. The PR03 is designed with an extra-wide fit to accommodate the broadest possible range of prescription glasses styles.

Will the PR03 fit over my prescription glasses? The PR03 is designed with an extra-wide frame specifically to fit over all glasses styles, including larger frames and wraparound prescription lenses. The inclinable side arms and moulded nose piece allow the fit to be adjusted to the individual wearer, and the soft rubber temple tips provide a non-slip grip that keeps the safety glasses securely in place over prescription eyewear during active work.

Do the PR03 safety glasses provide protection against UV radiation? Yes. The PR03 lens incorporates UV protection compliant with EN 170, guarding against harmful ultraviolet radiation. This makes the PR03 suitable for outdoor working environments including construction sites, utilities maintenance, landscaping, and agricultural applications where prolonged exposure to direct sunlight presents an eye health risk.

What do the EN 166, EN 170, and EN 172 certifications mean for the PR03? EN 166 is the primary European standard for personal eye protection, covering optical quality, mechanical strength, and field of vision requirements — the PR03's 1 FT marking confirms resistance to impacts from small particles at high speed. EN 170 covers ultraviolet optical filters, confirming the UV protection performance of the lens. EN 172 covers solar radiation filters for occupational use, confirming the lens provides appropriate protection against solar glare for outdoor working. Together, these three certifications confirm the PR03 as a comprehensively tested and compliant safety eyewear product.

Why do safety glasses fog up and how does the PR03 address this? Fogging occurs when warm, moist air from the face meets a cooler lens surface and condenses — a particularly common issue with OTG safety glasses, where the gap between the prescription glasses and the safety lens can trap warm air. The PR03 features an anti-fog coating on the lens that reduces surface condensation, maintaining clear, unobstructed vision during physically demanding tasks, temperature transitions between indoor and outdoor environments, and humid working conditions.

Are the PR03 safety glasses metal free? Yes. The PR03 is 100% metal free throughout its construction, making it suitable for use in environments where non-conductive PPE is required — such as electrical installation, utilities work, and any application where metal components in PPE present a safety risk.
