These days, it seems challenging to find someone who doesn't own a mobile device. We can't deny that these devices are wonderful, because they allow us to stay connected whenever we need to be. However because handheld devices sport small screens, a lot of people tend to hold their iPads and iPhones much closer than they would hold books and magazines. This gives way to a whole lot of demands on your vision that force your eyes to operate in a way that's quite a change from its normal activity.
Because everyone holds smart phones so close, the eyes need to work much harder to look at text and images. Over time, research shows this may cause difficulty with focus and vision, especially for those who already wear glasses. Some research shows evidence that when people who wear glasses spend a lot of time with their phone at a closer than normal distance, the eyes have difficulty correcting 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. Holding your smartphone too close can make you blink less, which can dry your eyes and blurry vision.
In order to stop these symptoms caused by our smartphones and tablets, as eye care professionals, we recommend that you hold the phone further away, and enlarge the text, so you can still read it. And try not to use your phone for too much time at once! If you've been on it a while, let your eyes have a little time away from the screen. If you still experience headaches, it might be time for glasses to help you focus up close. So be smart about how you use your mobile devices and care for your eyes to ensure you protect your vision.
