What is the warranty period for Costco frames in case of a defect?

The warranty period for Costco frames in case of a defect is indeed one year from the date of purchase. This duration is designed to provide customers with assurance regarding the quality and craftsmanship of their eyewear. A one-year warranty allows customers to address any manufacturing defects that may arise during normal use, ensuring that their investment in frames is protected for a reasonable length of time. This standard warranty period reflects the industry norm, helping to establish customer trust and satisfaction with Costco's optical products.

The other options do not align with the company’s policy on warranties, as shorter timeframes would not afford customers adequate coverage for potential issues that might only become apparent after several months of use. A one-year warranty offers a balance between customer confidence and the practical realities of product performance.
