Bilge Karga Lars Black Orange Cyclic Balance Glasses

Hello, the intended use of the model is to help maintain circadian balance. We recommend that you wear our orange lens models after sunset, in the evening, under artificial light or in front of the screen. All our products are UV400 protected, also suitable for outdoor use. However, to fully benefit from the lens's properties and allow your body to enter a state of relaxation, you can use it extensively in the evening hours I've specified. Thank you for your attention
