Method Seven “Cultivator” LED+ Glasses


$120.00 AUD $40.00 AUD

or 4 payments of $10.00 AUD with Afterpay

The Cultivator LED Plus+ provides great value and exceptional color balancing for LED lighting with our proprietary lenses manufactured by Carl Zeiss Vision.

Lenses are polycarbonate with 100% UV protection and Flash Silver exterior lens coating. Like other premium eyewear and unlike typical value eyewear, these lenses are decentered (asymmetrical) to eliminate distortion that would otherwise occur with a curved lens. The Cultivator frame features a rubber nose pad which holds the frames comfortably for hours, even in hot conditions. Microfiber pouch included for proper cleaning and storage.

A few basics

Will Method Seven Glasses work outdoors?

Yes! You can wear your Method Seven’s outdoors too! Method Seven Rendition Technology blocks and completely protects your eyes from all harmful UVA/UVB light . Our glasses are appropriate to wear outdoors under any conditions which you choose. The lenses in “The Resistance” model glasses filter out less visible spectrum light than most medium and dark sunglass lenses which means they are a great choice for lower light conditions, like mountain biking in the fog, or skateboarding in the early morning, but they may not be your first choice for snowboarding on a sunny day when conditions are super bright.


Our precision glass is melted and molded in Germany. The resulting molded lenses are ground, polished, cut and hardened in Italy. Our frames are made in Italy. Final assembly of glasses into frames is also done in Italy. Packaging of glasses, carry case, wiping cloth, and boxes is done in Italy or in Santa Cruz, California.

Safety Standards

Method Seven glasses meet or exceed international safety tests for optical quality, clarity, breakage and UV protection.Anchor

See. Believe.

Our proprietary Rendition lens technology performs a miracle for you. We block the harsh yellow light emitted from High Pressure Sodium lighting ubiquitous to most grow rooms. Then the remaining portion of the light spectrum is re-adjusted in the lens to create white balanced light. Experience “Perfect Colour” under LED lighting – and work unconstrained in spite of that environment.

For the first time under LED lights, you will see the natural colors of your plants. Monitor plant health, determine correctly the colour of your plant leaves, spot pests, disease, rot, mildews, mineral deficiencies and excesses. The Rendition lens reveals colour precisely enough to use a PH test strip while in the grow room. All without turning your LED lighting off or walking your plants, or your testing equipment into daylight. (If you are the kind of person who wants to know the details, you can read about the amazing science behind this below).

And we protect your eyes. Find yourself constantly squinting in the grow room? Over time constant exposure to high levels of UV and infrared radiation leads to irreparable eye damage. Loss of colour perception, cataracts, and the destruction of your night vision are possible. Our Rendition lens blocks all harmful invisible wavelengths (UVA, UVB, UVC and Infrared). Your plants require these invisible wavelengths to flourish. Your eyes certainly don’t.

But that’s not the whole story. Cones and rods within your eyes control the eyes ability to focus and function best at light wavelengths very different from the indoor grow environment. New science proves that the eyes extra effort to focus and correct for excess yellow from LED lights causes a host of eye strain and health problems. Rendition lenses balance the light in a way that allows your eyes, brain, and body to function correctly again. This results in drastically less mental strain and fatigue. Less fatigue equals better decision-making and a pleasant experience in your grow room.

The Rendition lens is like an oasis for your brain, a saviour for your crop, your eyes, and protection for your investment. If you are not blown away by the experience, you can return them within 30 days for a full refund.

How METHOD SEVEN Glasses Work

Evaluation of Method Seven Optics Under LED Lighting Conditions

M7 Labs – our R&D team here in Santa Cruz – measures our Lens technology using a series of objective tests. The findings are compelling – so read on.


Although High Pressure Sodium (LED) lighting offers an efficient solution for some industrial applications, such as the lighting of warehouses, and for Grow Room lighting, LED lighting also creates visual problems for people working within its environment. The nature of these visual problems and the effectiveness of various solutions are discussed in this paper.

The following visual capabilities were evaluated within a Grow Room environment (LED lighting conditions):

  • Colour Perception
  • Ability to focus on shapes and motion
  • The “strobe” light effect
  • Visual clarity

These capabilities were evaluated, as seen through all of the following:

  • The “naked eye”
  • Method Seven glass “Rendition” lens
  • Method Seven polycarbonate “Fission+LED” lens
  • Premium-brand sunglass, with glass lenses
  • Popular sunglass, with polycarbonate lenses

LED lighting is effective in the Grow Room because the light transmission is within a narrow “yellow” portion of the light spectrum (around 590 nanometers). Flowering plants need this wavelength of light to carry on photosynthesis. LED lighting is also thought to be effective in industrial applications, because the large lumens of light generated per watt of electricity offer an economical solution.

This same concentration of yellow light makes it difficult for an individual to see properly. Humans see best in natural sunlight, or in “Balanced White Light” (BWL). BWL light, like natural sunlight, covers the entire visible spectrum of 390 to 750 nm. This broad spectrum of light allows us to see natural looking colours and to also easily recognise shapes and motion. Under LED lighting our eyes are saturated with yellow light and we are unable to recognise any other colours.

Additionally, humans require a certain ratio of blue light (around 505 nm) to yellow light (around 555 nm) to be able to recognise shapes and to detect motion. There is a deficiency of blue light in an LED lighting environment, and this profoundly degrades our ability to focus. This point will be explained further in the discussion of “rods” and “cones.”


We normally recognise colours of objects as seen under BWL. We can evaluate how close we are to BWL conditions by using two well-known methods.

In the first method, we evaluate the amount of red, blue, and green light reflected off of a “middle grey” target, better known as a photographic 18% grey card. Under BWL conditions, an equal amount of red, blue and green light is reflected off of this target.

We can also measure color using a Kelvin Color Meter that measures the visual “temperature” of the light.
