Best for: reducing bright daylight before daytime sleep.
Turn harsh daytime light into a calmer evening signal.
When you finish a night shift, travel across time zones, or need to sleep while the world is awake, bright light can make it harder to wind down. These orange CR39 lenses are designed to reduce exposure to blue-toned light from daylight, screens, and indoor lighting.
The lightweight frame makes them easy to wear during your wind-down routine before daytime sleep, while the orange lenses help create a darker, calmer visual environment without needing to sit in a completely blacked-out room.
Light is one of the strongest environmental signals for your body clock. Research on sleep routines commonly points to light control as an important part of preparing for rest. By reducing bright, blue-toned light before bed, these glasses help create a calmer visual environment when you need your body to slow down.
Best used: 30–90 minutes before sleep, especially after night shifts or during bright daytime wind-down routines.
