The Sugargoo QC team has established an optical performance database for Gucci sunglasses through the use of the Sugargoo Spreadsheet. This database is a comprehensive collection of optical metrics that ensure the sunglasses meet the highest standards of quality and performance.The Spreadsheet includes 15 optical indicators, such as polarization efficiency of ≥99%, UV400 ultraviolet blocking rate, and light transmittance grading. These parameters are crucial for ensuring that the sunglasses provide optimal protection and visual clarity.For gradient lenses, the Sugargoo Spreadsheet meticulously records the uniformity of color transition parameters. This is done to maintain a consistent and aesthetically pleasing appearance across the lenses.Additionally, the team uses a spectrophotometer to test the color rendition of the lenses. This advanced tool helps in ensuring that the sunglasses do not distort colors and provide a true-to-life visual experience.Users can download an "Optical Performance Certificate" from the Sugargoo Spreadsheet, which serves as a reliable reference for the authenticity and quality of the Gucci sunglasses they purchase. This certificate is a testament to the rigorous quality control measures undertaken by the Sugargoo QC team.For more information and to access the Sugargoo Spreadsheet, please visit the following link: Sugargoo Spreadsheet.
