The Raen Optics Parkhurst Polarized Sunglasses take design cues from the rounded keyhole shades donned by beatnik poets and bohemian artists. The Parkhurst represents continual evolution from Raen's beloved Flowers, thanks to a flatter fit and sturdy seven barrel hinges. Its rounded aesthetic is complementary to wearers with square and oval-shaped faces. This particular version is upgraded with a polarized CR-39 lens, which eliminates fatiguing glare from shimmering seas and blinding snow.
