The Wegobuy Quality Control (QC) team has established an optical performance database for Gucci sunglasses through the use of a Wegobuy Spreadsheet. This database is a comprehensive collection of optical metrics for various models of sunglasses, ensuring that the products meet the highest standards of quality and performance.The Spreadsheet includes 15 optical indicators for each model of sunglasses, such as polarization efficiency (≥99%), ultraviolet (UV) blockage rate (UV400), and light transmission rate (graded according to the depth of color). These indicators are crucial for evaluating the sunglasses' ability to protect the eyes from harmful light while maintaining visual clarity.For sunglasses with gradient lenses, the QC personnel meticulously record the uniformity of color transition parameters within the Spreadsheet. They also utilize a spectrophotometer to test the color rendition of the lenses, ensuring that the sunglasses provide accurate color representation under different lighting conditions.Users can download the "Optical Performance Certificate" generated by the Spreadsheet, which serves as a professional authentication document. This certificate is a testament to the rigorous quality control processes undertaken by the Wegobuy QC team and provides customers with confidence in the optical performance of their Gucci sunglasses.For more information and to access the Wegobuy Spreadsheet, please visit the official website at https://www.wegobuy.cc.
