Have you ever thought about the effect your mobile device might be having on your vision? It's hard not to acknowledge that these devices are wonderful, because they allow us to be connected no matter where we are. Nevertheless a lot of people hold their handheld devices right in front of their eyes. This creates a number of visual demands that force your eyes to function in a different way than they usually do to read regular small print.
Because we all hold smart phones so close, our eyes end up working hard, just to look at text and images. It won't come as a shock to know that this can cause problems, particularly for people who already have vision correction such as glasses or contact lenses. If you already wear glasses, holding your phone or tablet too close to your face will make it a real challenge for your eyes to correct for distance. This puts strain on your eyes, and you wind up with headaches or migraines, which aren't pleasant.
But that's not all. There are more symptoms that can be caused by holding your device too close to your eyes, including dry eyes or blurry vision, which can result from staring at your screen for too long, which makes you blink less.
In order to prevent eyestrain and blurred vision caused by handheld devices, it's best to make the text bigger, and hold the screen further away from your eyes. It's also good to remember to frequently give yourself a rest from staring at your phone. You've only got one pair of eyes. Look after them well.
