It's official - we're totally dependent on smartphones. In truth, these devices are wonderful, because they allow us to stay connected whenever we need to be. Nevertheless as these devices are made with little screens, many users often hold their iPads and iPhones a lot closer than they hold books and magazines. Reading off the small screens that these devices feature can actually lead to a whole set of problems for your vision.
Small text and images make your eyes work much harder just to see clearly. Over time, this has been found to cause difficulty with focus and vision, especially if you already wear glasses. Specialists say that when such individuals spend a lot of time with their phone at a closer than normal distance, the eyes have an even harder time correcting for distance. When your eyes work too hard, it generally leaves you with unpleasant headaches or migraines as a result of the eyestrain.
Also, more time looking at your small screen can reduce your blink rate, and that can cause dry eyes and blurry vision.
But we can't all just stop using our phones. So what's the solution? In order to prevent these symptoms caused by handheld devices, it's best to use a larger font, and hold the screen further away from your face. Also, don't use your phone too much! If you've been on it a while, allow your eyes to have a little time away from the screen. You've only got one pair of eyes. Treat them well.
