Dusk Nighttime Blue Light Blockers are designed to regulate your appetite and hunger, enhance sleep quality, and ensure you wake up feeling refreshed and energized. These glasses block 100% of blue and harmful green light (up to 560nm) and decrease brightness by 15 times, creating an environment that naturally promotes melatonin production for deep, restful sleep. Wear them 1-2 hours before bed to ensure your brain isn't confused by artificial light signals. Dusk Nighttime Blue Light Blockers are scientifically engineered to emulate full darkness or the end of the fire, creating the perfect conditions for a restful night's sleep. By using these glasses, you can feel less stressed and anxious at night, regulate your appetite, improve your sleep quality, and wake up feeling refreshed and full of energy.
