Lately, it seems that we're addicted to our mobile devices. In truth, these devices are wonderful, because they allow us to stay connected whenever we need to be. Nevertheless as handheld devices sport little screens, most users usually hold their smartphones a lot closer to their eyes than they would hold books and magazines. This gives way to a whole lot of visual demands that force your eyes to work in a different way than they usually do to look at regular small print.
Because everyone holds smart phones so close, the eyes need to work much harder to look at text and images. Not surprisingly, this might cause issues, not least if you already use vision correction such as glasses or contact lenses. Specialists say that when people who wear glasses spend significant amounts of time holding a device at a closer than normal distance, the eyes have difficulty correcting for distance. This puts strain on your eyes, and you end up with headaches or migraines, which aren't pleasant.
There are other symptoms that can be caused by these habits, including dry eyes or blurry vision, because excessive screen time reduces how much you blink.
In order to stop these symptoms resulting from the use of handheld devices, it is recommended to make the text on your device much bigger and ensure that you hold your smart phone as far away from your eyes as you can. And try not to use your phone for too much time at once! If it's been a while, allow your eyes to have a rest. If you still experience headaches, it might be time for glasses to help you focus up close. Being smart about your smartphone will protect your eyes.
