Method Seven delivers the world's first and only sun / outdoor grow lenses, which also double for everyday use as sunglasses. Typical sunglasses filter out too much of the green and red spectrum for ideal observation of your outdoor plants. Improve your vision and enjoyment of your outdoor grow with our SUNp lenses—formulated specifically for outdoor gardening so that you can quickly detect pests, mineral deficiencies, and flowering. Method Seven Outdoor / Sun Grow glasses feature next level polarizing technology from Carl Zeiss, and proprietary “purps” anti-reflection coating. These are your new favorite shades!
