Lately, it seems that we're addicted to our mobile devices. We can't deny that these devices are wonderful, because they let us be connected almost always. However because handheld devices have little screens, many users usually hold their smartphones much closer than they would hold printed materials. This creates a number of visual demands that make your eyes operate in a way that's quite a change from its normal activity.
Because everyone holds smart phones so close, our eyes end up working hard, just to look at text and images. Over time, research shows this may cause problems with focus and vision, especially for those who already use vision correction, like glasses or lenses. Researches claim that when such individuals have a lot of small screen time, the eyes have an even harder time correcting for distance. Eventually, these challenges can result in eyestrain and headaches.
But there are more symptoms that can arise. Holding your device too close can make you blink less, which can lead to dry eyes and make it harder to see clearly.
In order to prevent these symptoms resulting from the use of handheld devices, we recommend that you hold the phone further away, and enlarge the text, so you can still read it. And don't use your phone too much! If it's been a while, allow your eyes to have a little time away from the screen. And after that, if you still experience headaches, you might be far-sighted, and need glasses to fix that. Come see us for an exam, if this is something you're concerned about. We all need technology, but it's important to be smart about how we engage with it, in order to help preserve our vision.
