CK19566S from the Calvin Klein Collection is a pair of men's rectangular sunglasses crafted in injection-molded plastic for everyday urban wear. The design balances flair with practicality, making them a solid choice for outdoor activities when you want a statement accessory. The frames boast refined finishes and attention to detail characteristic of the premium line. Measurements are 57-19-140 (lens width 57 mm, bridge 19 mm, temple length 140 mm). A 57 mm lens width tends to flatter oval, square, and rectangular faces. The silhouette offers a long, clean profile with straight lines that project a structured, modern look. The lenses deliver UV400 protection, blocking 100% of UVA and UVB rays, and carry a category 2 filter, making them suitable for driving and medium-light conditions.
