Method Seven designs specialty optics that provide unparalleled comfort, clarity and safety in unique and complex lighting situations. After 2 years of R&D, we proudly introduce the first scientifically researched and developed flight glasses for pilots. Our Sky formulated lenses enhance outside and instrument panel visibility under varying flight conditions. Our special non-polarized lens coatings eliminate ultraviolet and near ultraviolet radiation and provide superior eye protection against their long-term effects which are particularly damaging at high altitudes. M7 Sky glasses also do an unusually good job of filtering infrared light (a leading contributor to eye fatigue) and reducing reflection off the inner lens surface for a more relaxing and comfortable experience. Of course none of our Sky lenses are polarized. M7 Sky™ is a new creation blending rare-earth elements within crystalline lenses to notch filter specific high energy light. We custom design our lens coatings for numerous benefits to the pilot and both our Altitude and Ascent frames offer three unique VLT options that provide pilots choice between the darkest and lightest lenses available for pilots as well as a middle of the road solution. This uniquely covers the full range of normal to extreme conditions of high altitude flying. The SKY 9™ is our darkest lense and offers a unique experience for pilots frequently challenged with flight routes directly into bright sunlight. Our SKY 18™ is comparable to a standard sunglass in amount of light filtered but provides more contrast specifically for better instrument reading. Though our SKY 30™ filters less light than standard sunglasses, the enhanced contrast and strong filtering of 590nm yellow light provides great all day comfort and is a favorite for older eyes challenged in lower light conditions.
