We selectively target specific peaks of light spectrums created by grow lights. Beneficial peaks are amplified, while harmful peaks are filtered out allowing our lenses to achieve perfect color and light/dark balancing under extreme lighting. What is the best way to clean Method Seven eyewear? Clean lenses with warm water and micro fiber cloths only; use gentle dish soap sparingly when necessary. Avoid standard lens cloths which can lead to micro-scratches. Do not use products with alcohol, as they may damage lens coatings. How can I removed resin from Method Seven lenses without damaging them? Resin buildup can be safely removed by applying a small drop of coconut oil and rinsing with warm water.
