At nighttime, the properly functioning brain begins producing melatonin, the hormone that makes you sleepy. But, as mentioned on our Light Spectrum page , studies have proven that blue light has adverse effects on one's ability to fall asleep and stay asleep. It literally shuts down your brain's production of melatonin, making it more difficult to sleep.
The best way to solve this problem is to either remove the source of the blue light or block the blue light from your eyes during nighttime activities, which often involve large TV screens, monitors, tablets or even smartphones. All of these emit percentages of blue light higher than that of standard white light and other display devices. Since most of us don't want to change our nightly habits that much, wearing proper eyewear is a very simple and effective way to continue your activities while also helping you to fall asleep and stay asleep more easily.
BluGard nighttime eyewear not only comfortably dims your view, but has been laboratory tested to block 100% of blue light from your eyes, allowing your sleep-inducing melatonin to do its job properly. Alternatives use yellow lenses, which not only don't block all the blue light, but actually brighten your view, which is not something you want when preparing for your nightly rest.
BluGard glasses are Made In USA.
"The blue light frequency within regular light at nighttime interferes with the brain's production of melatonin and makes sleep more difficult. We have widely researched the Internet for glasses that block this blue light frequency, thus making sleep easier. From each company we researched, we requested specification sheets from their engineers. The BluGard glasses offered by safetyglassesusa.com are far more effective than any others on the market."
