When purchasing Calvin Klein glasses, ensuring the perfect fit is crucial for both comfort and style. However, there are instances where the glasses might not fit as expected. Fortunately, most retailers and official Calvin Klein stores have return or exchange policies in place for such situations.

Before making a return or exchange, it’s essential to review the store's specific policy. Many retailers offer a return window ranging from 14 to 30 days, provided the glasses are in their original condition with all tags and packaging intact. If the glasses were customized, such as prescription lenses, the return policy may be more restrictive.
