It seems like we can’t get away from them: Computer screens, smartphone screens, e-readers and televisions. They all emit UV400 light, the so-called “blue light” that’s been blamed for eye strain, headaches, and cramped necks. While the FDA doesn’t consider blue light glasses as medical devices, and doesn’t regulate their manufacture or use, that doesn’t mean they don’t have millions of fans. Here are three reasons blue light blocking glasses might be causing the pain in your head, eyes, and neck.
If long hours at your computer or gaming module are giving you eye strain, blue light from the screens could be the culprit. Choosing high-quality blue light blocking glasses will prevent the majority of these ultraviolet light waves from passing through the lenses into your eyes. Many users report near-instant relief from the eyestrain that comes from hours at work or play.
Harsh blue light can make you squint, and eventually alter the ergonomics of how you’re sitting at a computer screen. Squinting for a long period of time can definitely give your facial muscles a painful workout. Eventually you might arch your shoulders or hunch forward to try to give tired muscles relief. The solution could be as simple as blocking blue light from the computer screen, so your posture stays healthy over the long haul.
Blue light from screens and monitors could affect the body’s natural production of melatonin, a chemical that helps induce a deep, restful sleep. By blocking UV400 from your eyes, blue light glasses protect the circadian rhythms that govern a natural sleeping pattern. You just might go to sleep faster and wake up more restful than ever.
