The Benefits of Blue Light Blocking Glasses
Another day at the office often means another day of tired eyes staring at a computer screen. Sound familiar? After hours, you may find yourself watching the evening news or mindlessly perusing your Facebook news feed to recap the day in social media. Maybe you enjoy spending some quality time on your smartphone each night, playing word games with friends. No matter what your daily digital activity entails, chances are, you are being exposed to blue light in some form. We all are.
What is blue light, exactly? How can it impact our eyesight and overall health? And what can we do to improve our vision, with all our on-screen time? Below Adlens breaks down the dangers of blue light and the benefits of using blue light blocking glasses.
Blue Light Special
Artificial Light is a relatively new invention for the modern man, and there are studies that show it could be harmful to our health.
Before Edison’s grand invention, the sun was the main source of light. And so, for the most part, humans spent much of the evening hours in the dark. Aside from candles, campfires, and lanterns – all orange light – there was darkness. Bed and wake-up times must’ve been much earlier!
Now, our nights are brightly illuminated. Between TV, computers, tablets, and smartphones, there is a constant stream of visual consumption for us to enjoy. And, as a result, we are going to bed much later.
Aside from those old yellow bulbs a few of us keep around the house, much of that light we are using after sunset is blue light. Blue light mimics sunlight at its brightest phase. Researchers have found that this bright light at night throws off our body clock – a.k.a. circadian rhythm. How? It’s science. With blue light eye consumption after dark, our cortisol patterns are changed, and our natural production of melatonin is disrupted – making it harder to fall asleep. Experts at Harvard are also finding that blue light disruption may contribute to more serious health issues, such as cancer, diabetes, heart disease, and obesity. Night shift workers may have an even harder time with these health concerns. According to Harvard Medical School:
“Study after study has linked working the night shift and exposure to light at night to several types of cancer, diabetes, heart disease, and obesity. It’s not exactly clear why nighttime light exposure seems to be so bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer.”
In addition to concerns connected with our sleep, there is also the health of our eyes to consider. While all colors of light have the potential to cause some level of retinal injury, experts warn that the blue light from LED-devices has a shorter wavelength than other colors of light, bringing more energy to the eye compared to softer tones.
“Individuals tend to blink less frequently when mesmerized by what is on their screens, or by simply focusing on their work for extended periods,” says Dr. Raymond Iezzi, an ophthalmologist at the Mayo Clinic in Rochester, Minnesota. “This can worsen symptoms of dry eye and cause burning, irritation, and blurred vision.” All signs of digital eye strain.
How Blue Light Blocking Glasses Can Help
While the possible health effects of blue light can be concerning, you can take comfort in knowing there is a solution. Blue light blocking glasses! If you have trouble seeing your screen clearly at night – or even during your day-job – and are constantly straining your eyes, UZOOM Screen Protect can help. UZOOM Screen Protect are adjustable, computer reading glasses that block out 30 percent of blue light. In addition to helping you focus on all your blue-light-filled tasks, they also help protect against digital eye strain (which can cause headaches and blurred vision), promote better sleeping patterns, and may even protect against Macular Degeneration.
Blue light blocking glasses offer great eye protection. Natural Health Expert Dr. Joseph Mercola says that the benefits of blue light blocking glasses are “immense and varied.” In his view, he says, “The primary benefit is to prevent damage to the DHA essential fat in your retinal pigmented epithelium. This is responsible for converting sunlight into vital DC electric current your body needs.”
Blue light blocking glasses can also help increase our melatonin production, which we now know is critical for falling asleep. The University of Toronto recently studied two different groups of people. One group was exposed to bright indoor lights while wearing blue light blocking goggles and the other was exposed to regular dim light without wearing goggles. The melatonin levels were about the same in the two groups. This helps show that night owls, who are frequently reading or watching their screens, can benefit from blue light blocking glasses.
