Limited edition Mendo Dope grow glasses. Our synthetic lenses are manufactured for Method Seven by Carl Zeiss using Method Seven's unique lens technology and provide optimized color under HPS. And they provide exceptional clarity due to the high optical standards obtained by Carl Zeiss. They are very lightweight and unbreakable. We recommend our synthetic lenses to anyone with one grow light or who spends minimal time working under lights. The value of our synthetic lens makes these products great for outfitting larger crews who are working under lights but may not be making critical plant health and harvest decisions. Available either uncoated or silver coated (combining your indoor grow and outdoor lifestyle), 100% UV protection, and great value.
