That wider range — reaching into green as well as blue — is what separates it from the orange SleepAid lens, and it's why the tint is deeper: a Category 2 filter at 22.2% visible light transmission.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis is a lens for the last hour or two before bed, not for the working day. If you want something for evening screens that still lets you see colour normally, SleepAid Orange is the better choice.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eEvening light suppresses melatonin, and lenses like these reduce that suppression. That's the best-supported finding in this field; what it means for any individual's sleep is less settled, and our science page publishes both sides of it along with the full lab data.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eNot for night driving — at 22.2% visible light transmission, this lens is well under the 75% minimum required after dark\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e","brand":"Sleep ZM","offers":[{"title":"Default Title","offer_id":51235617177781,"sku":"Wayfarer Night-time Red Lens","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/1945\/9253\/files\/Night_TimeMAX_Wayfarer_Blue_Light_Glasses_Black_Main.jpg?v=1750501283","url":"https:\/\/sleepzm.com\/products\/sleepaidmax-red-merritt-blue-light-glasses-black","provider":"Sleep ZM","version":"1.0","type":"link"}
