For better or worse, screens have infiltrated just about every area of our daily lives. From our phones to computer screens, most of us are bathed in an eerie blue glow pretty much constantly.
Now, that's not to say screen usage is a bad thing. Screens help most of us do our jobs, stay in touch with our loved ones and even unwind after a long day with our favorite show. In fact, we're not here to argue against the many benefits of screens at all — except when it comes to your eyes.
You see, all of the screens you use emit blue light waves, which have a short, high-energy wavelength. By viewing screens, you invite that blue light into your eyes. And while many of the long-term dangers of blue light are still being studied, the biggest risk is to the health of your eyes and the quality of your sleep.
The process of staring at screens all day can leave your eyes dry and strained, causing headaches and disrupted sleep. In fact, blue light is believed to suppress melatonin — the relaxation hormone that helps regulate your sleep. That means that spending too much time looking at screens, especially in the evenings, could make falling asleep more difficult. Many sleep experts recommend shutting down the screens at least an hour before you aim to fall asleep, but that neglects to take into account the effect blue light may be having all day long. For instance, some research has shown that blue-light exposure can increase your risk of macular degeneration, which could affect your vision in the future.
Bottom line? Your eyes are important and deserve to be protected from these potential side effects. That's where blue-light blocking glasses come in. With specially treated lenses that block a portion of the blue light entering your eyes, blue-light glasses can counteract some of the negative effects of excessive screen use.
So, should you try blue-light blocking glasses? Well, it depends. If you're someone who spends most of your day working in front of a computer, you might be surprised to find the difference wearing blue-light blocking glasses can make. Just like you would wear sunglasses to protect your eyes from the sun, wearing lenses with blue-light filtering also helps keep your eyes safe.
No matter what, we don't expect screens to become less a part of our lives any time soon. Might as well protect our eyes (and look fashionable while doing it), right?
