Wear Blue-Blockers at night to protect your DNA and help assist your body with natural anti-aging anti-oxidants.  Melatonin is your bodies most powerful anti-oxidants and defined by science as the on & off switch to your body's life stages such as youth, old-age even death. The blue light spectrum has only been available to us from natural sunlight during the daytime only until just the recent century. Studies have now shown how important it is to block those blue-light spectra (495 - 380 nm) and keep the blue-light from negatively affecting your circadian rhythm, therefore your Melatonin production. Studies have shown that those using blue-blocking or ambient light only (no-screens at all) have significantly increased the quality of their sleep. I never get headaches until I was artificially being exposed to blue light at night, which studies have also shown to increase eye-strain and headaches. I personally sleep better and more sound using blue-blockers at night at least 3 hours before bed. I enjoy the style and comfort of these that I found plus have no issues when they cost less than $15 each. Try them out, you won't be disappointed as they also increase nighttime contrast so you actually see better!! Wow!
