Work safely in HPS grow rooms with stylish Citadel frames and lenses engineered for clarity, color balance, and UV protection.

Glasses built for HPS & mixed light HPS / LED rooms. Durable polymer lenses with a flash silver coating attenuate light while adding some serious style. This Italian-crafted wrap frame meets or exceeds ANSI-Z87+S standards.

Lens Technology

Method Seven grow room optics are designed using notch filtering technology to precisely block specific wavelengths of light to achieve color balance for each type of grow light. Then we trick them out using many different types of coatings across the various lens spectrums. A few examples include resin repel, anti-reflective, anti-fog, and petrol mirror for the absolute best clarity and durability.

• HPS Lens Technology - Designed for the intense yellow spectrum of High Pressure Sodium lights we use unique notch filtering technology to strip away the peaks of red & yellow in the 660nm range and balance the other wavelengths evenly. This provides an unmistakable experience of perfectly balanced color and comfort, with full UV protection under these incredibly yellow and hot lights.
• Grow Lens Technology - We use notch filtering to selectively and precisely block specific wavelengths of light energy to achieve a color balance for each specific type of grow light (HPS, LED). This provides perfect color, full protection, and comfort. We also use anti-reflective and hydrophobic coatings for the best clarity and durability. Choose your lens based on the light spectrum you are working under.

Frame Technology

Our Grow frames are designed in California and made in Italy with thermo-injected TR90 polymers. These materials can withstand the heat and professional rigors of the home basement grow or the biggest commercial facilities.

• CSA-Z94.3 Safety Rated - The CSA-Z94.3 standard, developed by the Canadian Standards Association (CSA), pertains to eye and face protectors. The standard specifies the performance criteria for different types of hazards. This includes impact resistance, lens quality, protection against optical radiation, and coverage area. At Method Seven, we use this as the benchmark and then raise it. We ensure our lens filtering exceeds CSA and keeps up with the changing indoor lighting technology because that's what we do best.
• ANSI Z87.1+ Safety Rated - American National Standards Institute—tested and certified to protect you from all the bad stuff. Don't just take our word for it—this is the benchmark. Growers trust Method Seven because we often exceed the benchmark—we work with lighting companies to know what's coming down the road and future-proof our lines.
• TR90 Frame Technology - Injected thermoplastic technology is the lightest, strongest way to make a sports or performance frame. If it's not titanium, it better be TR90.

• The Citadel - Safety that actually looks cool, The Citadel. This frame meets/ exceeds ANSI Z87+s safety requirements; meaning you are safe against projectiles. The Citadel features a slight wrap for maximum side protection and big, bold lenses for the best view of your garden. The Citadel is available in a slightly glossy gunmetal grey and a matte black finish. The Citadel is not just a catchy name, this frame is rock solid as a proper Citadel should be.
