Serengeti FasanoShiny Black / Polar PhD CPG LensesPresenting Serengeti Fasano from the high-tech Serengeti Sports Series. And its sleek, sophisticated frame suits most face shapes. Plus Serengeti's emblem appears on either temple for a truly refined finish.Fasano is made from grilamid TR90 for comfort and durability. Megol temple tips and nose pads hold these snugly yet firmly in position.Spectral Control fine tunes light transmission. So colours are vibrant and the view is sharp. Spectral Control also helps block most blue light (this type of light usually damages eyes and causes eye fatigue).These polarised sunglasses are photochromic too. So their lenses lighten and darken with the conditions (even inside the car where UV is minimal). And that built-in polarisation beats blinding glare – so there's no need to squint and eyes can relax.This one features CPG Lenses. This CPG (or “cool photo grey”) lens delivers unrivalled protection against glare (without colour enhancement). UV400 lenses. Serengeti sunglasses come with a one year manufacturer's warranty.
