Lately, it seems that we're totally dependent on our mobile devices. We can't deny that these devices are wonderful, because they allow us to be in touch with whoever we want almost always. Nevertheless as these devices are made with little screens, most people often hold their iPads and iPhones a lot closer to their eyes than they would hold newspapers and books. Reading off the small screens that these devices feature can actually create a whole set of challenges for your vision.
It's much harder for your eyes to focus on small images and text. This can cause issues, not least for people who already have glasses or contact lenses. If you already wear glasses, holding a device too close to your face will make it even harder for your eyes to correct for distance. This puts strain on your eyes, and you end up with headaches or migraines, which aren't pleasant.
But that's not all. Holding your device too close can make you blink less, and this can lead to dry eyes and blurry vision.
In order to stop eyestrain and blurred vision caused by our smartphones and tablets, it's best to set your phone to display all text in a larger font, and keep the screen further away from your face. It's also important to remember to regularly take breaks from staring at your phone. Learning to be smart about your smartphone will protect your eyes.
