Method Seven is the industry leader in cannabis eyewear. Having started out with just HPS color correction four years ago, they now have a full line of options for all different kinds of indoor lighting, including HPS, LED, and MH. What many people don’t know about Method Seven Glasses is that they save your eyes from harmful UVA, UVB, and UVC rays that are emitted by HID lights. Yes, you can actually harm your eyes over time in an indoor grow room, and regular sunglasses aren’t effective at correcting or color balancing for this environment. Even under fluorescents, Method Seven Glasses feel good to wear because they reduce the eye stress caused by compensating for the continuous flickering of ballast-based lighting of all kinds. Just released is their unique “photochromic” lens that transitions to a regular sunglass shade when outdoors, then back to HPS correction indoors. Price range is between $59-$169 based on the features. Visit methodseven.com to purchase a pair and for information that’s specific to your particular circumstances.
