In today’s society, people all around the world find themselves glued to a screen for hours on end a day. It’s become an epidemic, the constant scrolling, and typing, while these magical screens which show us the world in the palm of our hands can also be showing us a little more than our social media updates. HEV (High Energy Visible) Light emits from every device that we use on a day to day basis that has a screen. Everything from phones, to computer, tablets, and televisions emit this harmful high-energy light which can adversely affect every user’s vision.
HEV Light is also called Blue light and is a violet/blue light which omits from devices and can cause macular degeneration when interaction with it is prolonged. What is Macular degeneration you might ask? It’s an eye disease which causes vision loss, another scary thought, there are more than 200,000 reported cases of it in the US per year. It causes failure in the center field of vision because the center of your retina deteriorates, or leaky blood vessels grow under the retina. Even more terrifying, the condition cannot be cured and can cause lifelong problems. Blurred vision is the key symptom, but by the time it’s noticed it’s usually too late, although there are treatments that can make the condition more tolerable.
So, if HEV light causes such problems, why is it that millions of people are still staring at screens on a day to day basis? Some precautions and solutions can prevent overexposure to HEV lights and also protect you altogether from exposure. Many Devices come with light settings that adjust to more comfortable luminosity for the iris and cause less damage. There are also things you can do personally, like limiting the time you spend on devices to a certain amount of time or giving yourself breaks in between uses if it’s mandatory to use screen devices for work. For those who wear glasses, or even though who want to be cautious of the possible dangers of HEV lighting on their devices, there are anti glare glasses used to protect the eyes during device usage, which have become the most popular solution.
Those who use technology more often than others can also develop Digital Eye Strain, or Computer Vision Syndrome and combat dry eyes, headaches, and blurred vision. These users are usually prescribed medicated glasses which reduce glare from sources of light and protect the eye from stronger light energies. Anti-reflective coatings are placed on brands of lenses to help the everyday computer user or phone addict to protect their eyes from the dangers of looking at digital screens. We’ve all been warned before by our grandparents, not to sit too close to the television or we would go blind; that warning also applies to your phone and computer screens which we all keep a lot closer to our eyes than our TVs were. Precaution must be taken in many good things that come with the ever-changing and ever moving fast pace of society today, even with things that seem harmless. Every good thing should be used moderately, including technology.
