Alegria Nighttime Blue Light Blockers are the perfect solution for regulating your appetite and hunger, improving sleep quality, and ensuring you wake up 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. 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. Alegria Nighttime Blue Light Blockers help you achieve a more productive and focused day by improving your overall sleep quality.
