Digital Eye Strain (DES)
In the last two decades we have been using desktop and laptop computer screens of sizes between 14 inches to 21 inches and at an approximate distance of an arm’s length which is called as intermediate reading distance which is longer than our traditional book reading distance. This new visual activity has been known to cause eye strain symptoms called as Computer Vision Syndrome: In recent times in addition to traditional computer screens we have started using various digital devices like iPads, tablets, cellphones, digital books like Kindle, etc. These screens are smaller and need to be kept at a closer distance than the traditional computer screen and have become a daily, integral part of our lives. We’re constantly texting, researching, working, and goofing around on our smartphones According to various studies on usage of digital devices, on an average an individual spends 7.5 hours in front of a screen or digital device every day. This prolonged exposure to digital devices prompts uncomfortable consequences and side effects. The American Optometric Association estimates that over 50% of computer users suffer symptoms of Digital Eye Strain including the earlier version of Computer Vision Syndrome which, quite literally, feels like eye strain, eye discomfort, and eye fatigue.
