The classic aviator gets a sporty, functional, and of course, fashionable update. The Ray-Ban 3478-004 78 Sunglasses are fashioned from a light gunmetal with adjustable nose pads that allow for a comfortable all-day wearable experience. The rectangular lenses feature a flattering crystal polar Blue Gradient shade that not only provides 100% protection from the sun's harmful UVA and UVB rays, but are also polarized. Polarized lenses cut down on sun glare, which also cuts down on eye fatigue from having to squint too much. How about that, no more forehead and eye wrinkles, WOO HOO! These rectangular lens sunglasses have been outfitted with comfortable plastic temples and resistance-enforced hinges for strength. The matte black arms have the tonal Ray-Ban discreetly displayed on the temples, as well as the embossed Ray-Ban "P" (for polarized) on the upper right-side lens. These shades are not just super cool, but they are a perfect combination of comfort, strength and style. There's a reason why Ray-Ban has been an eyewear fashion leader since 1937, and these sunglasses are one of those reasons.
