The human eye is an incredible organ capable of a wide variety of tasks. Unfortunately, the smartphone culture is drastically reducing the amount of long-distance focusing we do, instead locking our gaze a few inches away from our face and keeping it there. Experts advise that prolonged screen usage can be seriously detrimental to eye health, but they’re just not sure how bad it truly is yet. Lab experiments show that prolonged exposure to HEV light, like the kind emitted by LCD screens, damages retinal tissue, and the closer the screen is, the more of that radiation is absorbed.
Moreover, staring at a screen for long periods causes our eyes to become dry, and we produce fewer natural tears than we should. Juggling between computer and phone, most people stare at a screen all day long and don’t blink often enough. Not blinking as often as we should can lead to excessive eye strain, headaches, fatigue, and vision problems. Try and limit the time you spend per day on these devices, and if you can’t because of work, it’s essential to schedule frequent breaks.
