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 Light They block short - wavelength light in the 400nm to 550nm range, which is often called the \"melatonin disruption zone\". 3. Working Principle - Supporting Hormone Production By 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 Quality Using them regularly may help you fall asleep faster, wake up less during the night, and feel more refreshed in the morning. 5. Usage Time Wear them in the evening, usually 2 - 3 hours before going to bed. 6. Usage Scenario Use them when you're around artificial light from devices like computers, phones, and tablets. 7. Special Consideration for Prescription If 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 Issues The 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.\u003c\/p\u003e","brand":"Eyekepper","offers":[{"title":"Default Title","offer_id":45410055127087,"sku":"B0G2Q6LRM7","price":57.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/3498\/9615\/files\/61YHhaFC6qL._AC_SL1500.jpg?v=1780429410","url":"https:\/\/www.coziecorners.com\/products\/eyekepper-metalless-screwless-blue-light-blocking-glasses-spring-hinges-for-computer-gaming-2","provider":"CozieCorners","version":"1.0","type":"link"}
