Designed for long days on screens where you want a softer view without noticeably changing colors.\u003c\/p\u003e\n\u003cp\u003eStraight about the evidence: we're not going to tell you screen light damages your eyes. The American Academy of Ophthalmology's position is that there's no good evidence it does, and a 2023 Cochrane review found blue-light filtering lenses probably make little or no difference to eye strain. Some people simply prefer how a clear filter feels at a screen.\u003c\/p\u003e\n\u003cp\u003eWhat UV400 protects against is real and well established. Everything else is on our \u003ca href=\"https:\/\/sleepzm.com\/pages\/science\"\u003escience page\u003c\/a\u003e. If your goal is evening wind-down before sleep, the tinted SleepAid range filters far more.\u003c\/p\u003e","brand":"Sleep ZM","offers":[{"title":"Default Title","offer_id":45330161008821,"sku":"2J-XR1G-I4HX","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0532\/1945\/9253\/files\/Daytime_Wayfarer_Blue_Light_Glasses_-_Crystal_Main.jpg?v=1746720536","url":"https:\/\/sleepzm.com\/products\/invisiaid-clear-merritt-blue-light-glasses-crystal","provider":"Sleep ZM","version":"1.0","type":"link"}
