The Wegobuy QC team has established an optical performance database for Gucci sunglasses through the Wegobuy Spreadsheet. This database is a comprehensive collection of optical specifications for various models of sunglasses, ensuring that customers receive products that meet high-quality standards.The Spreadsheet includes 15 optical indicators for each pair of sunglasses, such as polarization efficiency (≥99%), UV blockage rate (UV400), and light transmission rate (graded according to the depth of color). These indicators are crucial for assessing the sunglasses' performance and ensuring they provide the necessary protection and visual clarity.For sunglasses with gradient lenses, the QC personnel meticulously record the uniformity of color transition parameters within the Spreadsheet. This attention to detail ensures that the color transition is smooth and visually appealing.In addition to the recorded parameters, the QC team uses a spectrophotometer to test the color rendition of the lenses. This advanced equipment helps in verifying that the lenses accurately represent colors, which is essential for maintaining the integrity of the Gucci brand's design.Customers can download the "Optical Performance Certificate" generated by the Spreadsheet, which serves as a professional authentication of the sunglasses' optical performance. This certificate is a testament to the rigorous quality control process that Wegobuy employs to ensure that every pair of sunglasses meets the highest standards of optical performance.For more information or to access the Wegobuy Spreadsheet, please visit Wegobuy's official website.
