Are these blue-blocker sunglasses (amber/orange tinted) or are these blue coated daily eyeglass lenses? The daily ones help relieve eyestrain from viewing screens all day, but only block about half of the blue light coming from screens-and as such have minimal effect on sleep per se. The blue-blocker sunglasses are for use after sundown and do prevent 95-100% of blue light after sunset-most important to allow melatonin to be released at the appropriate sleep-inducing time.
