1. Basic Function"Sleep glasses", also called blue light blocking glasses, are made to be worn in the evening. They filter out blue and green light from screens that can mess up sleep patterns.2. Working Principle - Blocking LightThey block short - wavelength light in the 400nm to 550nm range, which is often called the "melatonin disruption zone".3. Working Principle - Supporting Hormone ProductionBy cutting down on exposure to blue light from screens, they help keep the body's natural production of melatonin (the sleep - regulating hormone) going. 4. Working Principle - Improving Sleep QualityUsing them regularly may help you fall asleep faster, wake up less during the night, and feel more refreshed in the morning. 5. Usage TimeWear them in the evening, usually 2 - 3 hours before going to bed. 6. Usage ScenarioUse them when you're around artificial light from devices like computers, phones, and tablets. 7. Special Consideration for PrescriptionIf you need glasses with a prescription, you can get sleep glasses made to your prescription or use fit - over versions to put over your existing glasses. 8. Potential IssuesThe amber or red lenses can change how you see colors, making it hard to see some colors correctly. Also, don't wear them while sleeping as it can be uncomfortable and may damage the glasses.

• Promote Natural Sleep - Block disruptive blue-green light from screens before bed. This supports your body's natural melatonin production, helping you wind down and fall asleep more quickly and easily for a better night's start.
• Improve Deep Sleep Quality - By protecting your natural sleep cycle, these glasses promote more consistent and deeper sleep. This leads to fewer nighttime awakenings, helping you wake up feeling truly rested and rejuvenated each morning.
• Targeted Light Blocking - The specially designed red lenses are scientifically calibrated to block disruptive wavelengths in the 400-550nm "melatonin disruption zone," effectively filtering artificial light from digital devices for robust nighttime protection.
• Easy Evening Integration (Remove Before Sleep) - Easily wear them 2-3 hours before bedtime while using electronics. For safety and comfort, simply remember to take them off when you go to sleep, making them a seamless part of your wind-down ritual.
• Effective Protection - The noticeable red tint causes color distortion because it is effectively filtering the specific blue and green wavelengths that disrupt sleep. This confirms the glasses are actively working to protect your melatonin production.
