These days, it would be challenging to find someone who doesn't own a mobile device. In truth, these devices are wonderful, because they allow us to be in touch with whoever we want no matter where we are. However as handheld devices are made with small screens, a lot of users often hold their smartphones much closer to their eyes than they hold newspapers and books. Reading off the small screens that these devices feature can often lead to a whole set of problems for your eyes.
It's a challenge for your eyes to focus on small images and text. Not surprisingly, this might cause problems, particularly if you already use 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 even harder for your eyes to correct for distance. This puts pressure on your eyes, and you end up with headaches or migraines, which aren't pleasant.
But that's not all. There are more symptoms that can result from these habits, including blurred vision and dry eyes, which can result from staring at your screen for too long, which lessens your blink rate.
In order to stop these symptoms resulting from the use of handheld devices, as eye care professionals, we recommend that you hold the phone further away, and enlarge the text, so you can still read it. It's also recommended to try using your device for less time, and giving your eyes regular breaks. We all need technology, but it's crucial to be smart about it, in order to help preserve our vision.
