You can easily identify your eyewear model using the SU number located on the inside of the temple. Please note: The word “CORE” on the inside of the temple simply describes the bioplastic blend used for the frame and is not the name of the eyewear model. Therefore, you will unfortunately not find any eyewear under the name “Core” in our product range.
Attached you will find a table listing all sports eyewear models and their corresponding SU numbers. The first three digits of the number describe the model, while the remaining digits indicate the frame color.
