Grow Room Glasses

What makes Method Seven different from other grow room glasses?

Quality and materials. Eye protection and color correction are essential for those working under high pressure sodium (HPS) lights. Our HPS grow room glasses are made with mineral glass instead of cheap plastic, allowing for better technology to create perfect vision, ultimate comfort, and supreme protection. The rare earth metals in our grow glasses remove the high energy spike HPS lights emit, while also removing the stroboscopic effect of HPS bulbs. Our synthetic lenses are crafted by Carl Zeiss, world leader in optics manufacturing. Our lenses are never bent to fit into frames. This manufacturing technique typical of cheap glasses causes major distortion and discomfort.

Which lenses do I need for my Ceramic Metal Halide lights?

The best option for ceramic metal halide glasses is the Agent 939 LEDFx. Originally designed for full spectrum LEDs, the Agent 939 LEDFx has the subtle color balance and complete protection necessary for ceramic metal halide lights; they also offer superb contrast, UV & infrared protection.

What's the difference between the green LED+ lenses and pinkish LEDfx lenses?

The LED+ lenses offer profound color balance for red/blue to magenta spectrum LED grow lights (EXAMPLES: KIND LED or Black Dog LED). The LEDfx lenses are designed for full spectrum LED lights, offering subtle color balance to enhance contrast (EXAMPLES: FLUENCE LED or Spectrum King LED).

Which lenses should I order if I use both MH and HPS lights?

HPS lights will overpower the bright white MH light. You're good to go with any of our HPS grow glasses. If you have the HPS lights and MH lights in separate grow rooms, rather than mixed together, you'll have a better experience with the appropriate lenses for each grow room.

What's the difference with all of the HPS options?

Our favorite HPS grow room glasses are the “Perfect Color” HPS+. These premium mineral glass lenses offer the most profound color balance, cooling, and clarity available. Glass lenses are a challenge to make, but they sure make for an amazing visual experience. HPSx Transition optics refer to transition grow glasses. Photochromic technology reacts with direct sunlight to transition the sunglasses from blue to a soft grey within a few minutes of exposure. Our polycarbonate HPS+ grow glasses attenuate and balance the HPS spectrum. They are manufactured in partnership Zeiss optics, guaranteeing your distortion and haze free clarity and comfort.

Does one set of grow glasses work for all grow room lights?

No. Our notch filtering technology works so well as it very specifically filters out some wavelengths of light while allowing other wavelengths to pass information to the eye. Each M7 lens is a filter highly tuned to its namesake light spectrum. It's not possible for a single lens to properly filter light for vastly different spectrums. As with filters, if the input changes, so does the output.

Prescription Sunglasses

Can you make prescription sunglasses?

Prescriptions pilot sunglasses are available in the Ascent Aviator SKY 24. Prescription grow room glasses will be available soon. Contact us to be added to the waitlist.

How long do prescriptions take?

Our performance SKY24 prescription pilot sunglasses take about 3-5 weeks to create. Please note, there are occasional production flaws and we may opt to have your lenses remade if we feel they are less than perfect, this may add 1-2 weeks. The expedited shipping service will be fulfilled once your prescription sunglasses are ready, but selecting this service does not shorten processing time.

I need progressive lenses. How will you get my measurements?

Within 1-2 business days of placing your order, a Measurement Kit will be shipped to you (at no additional cost), to be taken to your local optician. The kit includes a sample frame, Rx form, and pre-paid return postage. The sample frame has lenses that may be marked by your optician. Upon return of your kit we submit your order for processing.

Can you make prescription bifocals?

Our bifocals are “readers.” They have flat-line magnification in the lower lens with NO forward vision correction in the top of the lens. If you need forward vision correction, please order the progressive option. We cannot accommodate forward vision correction with flat-line bifocals.

Do you accept insurance?

While you may check out with your flexible spending debit card, we do not bill insurance. We can provide an invoice indicating your prescription upon request.

Pilot Sunglasses

What makes Method Seven different from other sunglasses? Everything! Our notch filtering technology optics enhances contrast while preserving your peripheral view, and 13 coatings cut through glare without screen disruptive polarization. Our hand-tooled Japanese Titanium frames make our pilot sunglasses headset and oxygen mask compatible, allowing visual comfort and ease from takeoff to wheels down.

What is VLT%?

Visual light transmission, or VLT, refers to the percentage of light passing through the lenses. Our SKY18% lenses filter out 82% of light, allowing a visual light transmission of 18% (about average). SKY9% lenses are the darkest and SKY30% lenses are the lightest.

Are your PILOT sunglasses polarized?

No. We make top-notch non-polarized pilot sunglasses, so that pilots can view their instrument panel and see through the windscreen without distortion. Our notch filtering technology cuts through glare without polarization.

Do your PILOT sunglasses block blue light?

While our lenses adjust blue light, we do not condone completely blocking blue light. Blue light is an important range of the visual color spectrum, and it assists with both peripheral vision and contrast perception. We reduce higher energy blue light while preserving areas of helpful information. Blue light wavelengths are too large to penetrate human cells like UV.
