Graceful and sleek, CK577 full framed prescription glasses from the Calvin Klein collection are smooth in slate-colored titanium! When these glasses are near light, they give off a slight blue hue for something a little different. These classy eyeglass frames are larger towards the outside and narrower toward the inside of the lens for a balanced effect. The words "Calvin Klein" are embossed on the inside of the temple for a truly designer look.
