The band around 450 to 480 nm is the one research links to suppressed melatonin and a later body clock, because the eye is most sensitive to those wavelengths after dark.\u003c\/p\u003e\n\u003cp\u003eA tinted lens filters by absorption: the dye in the lens absorbs that short-wavelength light before it reaches your eye, so less of the activating part of the spectrum gets through. The warmer view you see is the result of removing the blue end, not a coating laid on top.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAmber\u003c\/strong\u003e absorbs the high-energy blue band (about 400 to 480 nm) in a lighter everyday tint. \u003cstrong\u003eWine red\u003c\/strong\u003e is a deeper tint that reaches further into the blue-green range, so it removes more of the activating light for the last hour before sleep.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp class=\"nd-note\"\u003eWear them in the hours before bed, from after dinner until you put the screen down.\u003c\/p\u003e\n\u003cdiv class=\"nd-offer\"\u003e\n\u003cdiv class=\"t\"\u003eWind-down perks\u003c\/div\u003e\n\u003cdiv class=\"d\"\u003eFree shipping. 30-day easy returns.
