Bilge Karga Lars Black Red Circadian Balance Glasses

Hello, our product provides the protection you are looking for by completely blocking blue light and cutting green light by 98%, which suppresses melatonin secretion. We just remind you that the most distinctive feature of the model is the environment and the fact that it obscures the screen by about 78% (22% transmittance). The blue and green tones on the screen are filtered out as red/black, resulting in a dim image. You can comfortably choose it to maintain your circadian rhythm during screen usage that does not require intense visual focus before going to bed. Thank you for your interest.

Hello, the purpose of the model is to help maintain circadian balance. We recommend wearing our red lens models in the evening, 1-2 hours before bedtime. All our products are UV400 protected and are suitable for use during the day. However, you can use it intensively during the hours I specified to fully benefit from the features of the eyeglass lens. Thank you for your interest.

Hello, our model has CR39 Organic Lens. Thank you for your interest.
