The Smith Shift Split MAG sunglasses deliver race-ready performance for cyclists, runners, and outdoor athletes who demand unobstructed vision and rapid adaptability. The half-rim shield design eliminates the lower frame entirely, opening up your field of view while shaving weight—you get goggle-level coverage without the bulk.
Smith’s MAG interchangeable lens technology uses magnets and dual locking toggles on each temple to secure the lens. Release the toggles, lift out the old lens, snap in a new one—no bending the frame, no fingerprints on the glass. Each pair ships with a bonus clear lens, so you’re covered from dawn starts to midday sun. The magnetic system holds firm through rough descents and hard efforts; the toggles lock the lens in place so it won’t pop loose when you need it most.
ChromaPop lenses filter two specific wavelengths where colors overlap and cause confusion—the blue-green and red-green crossover points. By blocking these intersections, your brain recognizes truer, more vibrant color with less effort. The result is sharper contrast, better depth perception, and reduced eye fatigue on long rides or runs. Whether you choose a mirrored lens for bright days or the photochromic Clear to Gray option (20–85% VLT) that adapts automatically as clouds roll in, ChromaPop ensures you see terrain details clearly.
Built for medium to large faces, the Shift Split MAG features a 5-base cylindrical shield with slight wraparound coverage. Two-position adjustable Megol nose pads and Megol temple grips become tackier when wet, keeping the frames stable through sweat and speed. The high-impact TR90 nylon frame is lightweight and durable, and AutoLock hinges hold the arms open for easy one-handed on-and-off. Smudge- and moisture-resistant coatings keep optics clear.
The Shift Split MAG is compatible with Smith’s snap-in prescription adapter for riders who need Rx correction. All lenses provide 100% UV protection.
