We spend more time than ever on all of our digital devices including smartphones, laptops, tablets, TVs, and home computers.
They all produce artificial Blue Light and don’t forget the amount of exposure we get from LED lighting, which also emits Blue Light. What is this exposure doing to our eye health and our overall health and well-being?
Along with smartphone usage, we are all, adults and children alike, in front of laptops, tablets, and home computers more than ever for both work and school. Recent studies have shown that the majority of our waking hours are spent in front of a digital screen. 60% of people are spending more than 6 hours a day in front of a digital device. And that number is only going up for the majority of us! This exposure to these devices has greatly increased our overall exposure to Blue Light.
What is Blue Light? Simply put, there are two sources of Blue Light. Natural (from the sun) and artificial (as mentioned above). Blue Light waves are the shortest, highest-energy wavelengths in the visible light spectrum. The natural form of Blue Light has actual benefits such as regulating natural sleep cycles, boosting alertness, and elevating moods. Because Blue Light wavelengths are shorter, they flicker more. And when emitted from artificial sources, it’s this flickering that can reduce visual contrast and affect sharpness and clarity. Our eye’s natural filters do not provide sufficient protection against Blue Light rays from the sun, let alone from these highly used artificial sources. In addition to some potential long-range health problems such as age-related macular degeneration, digital eyestrain is a serious symptomatic problem. Symptoms include blurry vision, difficulty focusing, dry and irritated eyes, back and neck pain, and headaches. Digital eyestrain has overtaken carpal-tunnel syndrome as the #1 computer-related complaint. A recent study by the Kaiser Family Foundation showed that children aged from eight to eighteen spend more than 7 hours a day consuming electronic media. This was before online schooling!
Who needs protection from Blue Light exposure? The answer is easy. We all do! Think of it as the same basic idea and principle as applying sunscreen before going out in the sun. A quality Blue Light Lens will do the following: Block 100% OF UV rays, filter out harmful energy blue light while allowing good blue light in for quality color perception, protect from artificial lighting, and reduce glare to prevent squinting with included anti-reflective properties built in the blue light lenses. These are just some of the benefits! So protect yourself and your children from potentially permanent eye health problems along with the problematic symptoms of digital eye strain, and get a pair of Blue Light lenses today!
