The Olser sunglasses from Sinner feature an optical rim and interchangeable lens system allowing for customization and versatility in various lighting conditions. The inclusion of multiple lenses, including a Cat. 3 mirror lens, an orange Cat. 2 lens, and a clear Cat. 0 lens, makes these sunglasses suitable for a range of outdoor activities. The lenses' 100% UV protection is also crucial for protecting your eyes from harmful sun rays. In addition, the flexible non-slip nose pads make sure that the sunglasses stay comfortably in place, even during times of high movement.Optical adaptorStorage case Decentred polycarbonate lenses100% UV protectionMulti lens Cat. 3, CAT. 1 and CAT. 0Anti-slip temple tips and nose padsAdjustable temple tips and nose padsFree storage box for sunglasses and lensesAsian Fit
