The Method Seven Ascent SKY18 combines classic aviator styling with advanced optical technology engineered specifically for pilots. Featuring nonpolarized SKY mineral glass lenses with 18% visible light transmission (VLT), these aviation sunglasses offer a versatile medium tint for most daylight flying conditions, from clear skies to mixed cloud cover. Developed by M7 Labs in Santa Cruz, California, SKY lens technology uses proprietary notch filtering to balance colors, enhance contrast, and reveal detail in clouds, terrain, and flight instruments. The blue mineral glass lenses provide exceptional optical clarity and scratch resistance, with full UV protection and infrared filtering to reduce unwanted heat. A blue flash mirror finish and anti reflective coating help manage harsh sunlight and distracting reflections. Unlike polarized sunglasses, SKY lenses allow pilots to view electronic flight displays, GPS units, and iPads without polarization interference or distracting patterns through aircraft windows. The Ascent's aerospace grade titanium frame offers lightweight strength, flexibility, corrosion resistance, and lasting durability. Its modern aviator design features slim bayonet temples that taper to less than 1.00 mm, fitting comfortably beneath aviation headsets and flight helmets. The ultra thin profile helps maintain headset ear seals and noise attenuation, minimizing sound leakage, pressure points, and discomfort during long flights. The flexible frame also accommodates oxygen equipment without unnecessary interference, while adjustable rubberized nose pads provide a secure fit. Developed and tested with pilots, the Ascent SKY18 brings together precision optics, dependable comfort, and aviation specific engineering. Lenses are drop ball tested for impact resistance. Frame measurements: 58-14-140 mm with a base 6 lens curve. Includes a protective hard case and microfiber pouch.
