Description
Safety-rated HPS glasses for hands-on grow room work
The Method Seven Citadel HPS+ puts Method Seven's HPS lens filtering into an ANSI Z87+S safety-rated frame, built for high-impact protection while you prune, train, hang lights or work around equipment. The lens balances the extreme yellow of high pressure sodium lamps towards neutral white light, reducing harsh spectral spikes, eye strain and the afterimages that linger after a long session, while keeping colour and detail clear. A flash silver coating on the lens tones down glare.
The Citadel frame has a slight wrap for full coverage, is made from TR-90, has 57 mm lenses and a 19 mm bridge, and fits average to large faces. It is a practical, good-value way to equip everyone who works an HPS room.
Key Benefits
- ANSI Z87+S safety rated – high-impact protection for physical work
- Neutral colour under HPS – pests, deficiencies and mould are easier to spot
- Less eye strain and fewer afterimages on long sessions
- Flash silver lens coating to cut glare
- Slight-wrap TR-90 frame – full coverage for average to large faces
Safety and Colour in One Pair
A working grow room asks two things of your eyes at once. The lamps flood everything with colour-distorting HPS glare, and the job itself brings knocks – a springing branch, a trellis net, a tool or fixture close to the face. Fashion sunglasses help with neither. The Citadel's safety-rated frame and lens take the impact, while the HPS filtering keeps leaf colour true, so plant health problems are caught before they spread.
How to Use
- Wear them as everyday eye protection whenever the HPS lamps are on and you are working in the room.
- Made for HPS: for LED rooms Method Seven make the same Citadel frame with an FX2 lens.
- Clean with a soft microfibre cloth to keep the coated lens clear.
- Keep them away from lamp heat when not in use.

Frequently Asked Questions
Are these proper safety glasses?
Yes. The Citadel is ANSI Z87+S rated for high-impact protection, so it doubles as eye protection for pruning, training and work around equipment.
How is this different from Method Seven's glass-lens models?
The Citadel uses a tough polycarbonate HPS lens in a safety-rated frame. Models such as the Resistance HPS+ use a mineral glass lens that is more scratch-resistant but not safety rated.
Can I use them under LED grow lights?
No. This lens is tuned for high pressure sodium. Method Seven make the Citadel with an FX2 lens for full-spectrum LED rooms.
