Calvin Klein glasses are elegant, sophisticated and feature simple and clean lines. Calvin Klein designs very provocative luxurious fashion collections, sporting brave design choices, artistic style and a knack for colourful combinations. The Calvin Klein brand has a strong and consistent identity recognisable at first sight. The unisex glasses Calvin Klein CK21700 001 17 54 are equally popular with all genders. Glasses frame The black colour of the frame perfectly matches a cool skin tone and light blonde, light brown or black hair. Rectangle frames are an ideal choice for those with an oval or round face shape. The frame of the glasses is made of a combination of metal and plastic. It offers high durability, stability and extraordinary sty­le. Full-rimmed glasses have the most common types of frames which consist of a frame front and a pair of temples. They will elevate and complement your style thanks to their noticeable design. One of their advantages is sturdiness, durability, the fact that they fully enclose the lens, and mainly their protection against damage. This type of frame is suitable for all lenses, including lenses with higher optical power. Spring hinges afford the arms a greater movement to more than 90° which results in higher wearing comfort. The frames are more damage resistant and maintain the right fit longer. Accessories We deliver the glasses in their original case. The colour of the case and its design may vary.
