Calvin Klein CK18509SG Round Grey Gradient Sunglasses — Black

Calvin Klein's acetate round sunglasses balance bold geometry with refined proportions. The black frame features light blue inner arms and gradient lenses that deepen from translucent at the top to opaque grey. Sculptural hinges with signature studs add definition, while the generous 55mm lens width suits most face shapes. Wear solo for everyday calm or layered with a warm-toned palette to amplify the cool-toned frame.
