Blue light is a spectrum of light present in almost every facet of our lives. Blue light is everywhere! We mainly experience it from our exposure to the sun, but it is also emitted by the screen on a digital device. That means that even after the sun goes down, our eyes continue to be exposed to blue light from our computers at work, our smart phones, and our televisions long into the night. Since our lives have become so much more high-tech than in the past, the amount of blue light we’re exposed to each day has skyrocketed. Today, it is a widely known fact that constant exposure to blue light can result in some serious eye health issues. However, not as many people know exactly where blue light comes from, or how to properly defend against it. If you’ve ever wanted to learn more about blue light and the importance of computer glasses, then this is the article to read. EyeBuyDirect’s got all the info you could want, starting with your most popular questions.

How bad is blue light for you?

Heavy exposure to blue light can create all sorts of health complications. In the short term, blue light can cause serious eye strain and discomfort. In the long term, it can rapidly speed up macular degeneration at a young age, and can even create cataracts in your eyes.

Is blue light bad for sleep?

Blue light is bad for sleep. Scientists from all over the world, including top-level experts from the Paris Vision Institute, agree that receiving blue light from a digital screen can negatively impact both the quality of your sleep and your sleep schedule.

Why does blue light keep you awake?

Blue light keeps you awake by emitting a portion of light that can also be found in the sun’s rays. When the sun is out the human body recognizes that it’s time to be active and energetic, so it naturally produces less melatonin (the biological chemical that induces sleepiness). So, when your eyes receive blue light emitted from your smartphone, tablet, and television past sundown, your body is tricked into thinking that it is still day time. Your melatonin production is lowered, which means that you will have a harder time falling asleep normally.

How to protect against blue light?

To block out blue light, a pair of specially crafted computer glasses are a must. Why? Because the naked eye is not good at all at protecting against it naturally. Computer glasses give you an added layer of protection by filtering out blue light with a special lens coating. The difference in vision is extremely subtle and almost indistinguishable from normal glasses — while the eye health benefits are many.
