Lately, it seems hard to find someone who doesn't own some sort of smartphone. These devices ensure our access to our email, text messages and the Internet no matter where we are. However as handheld devices sport little screens, most users often hold their smartphones much closer than they would hold printed materials. This creates a whole lot of demands on your vision that force your eyes to function in a way that's different to its normal activity.
It's a challenge for your eyes to focus on small images and text. Over time, research shows this may cause difficulty with focus and vision, especially for those who already use vision correction, like glasses or lenses. If you already wear glasses, holding your phone or tablet too close can make it even harder for your eyes to correct for distance. When your eyes are under unnecessary pressure, it usually leads to unpleasant headaches or migraines as a result of the eyestrain.
But that's not all. There are other symptoms that can be caused by these habits, including dry eyes or blurry vision, which can result from staring at your screen for too long, which makes you blink less.
In order to stop eyestrain and blurred vision resulting from the use of our smartphones and tablets, it's best to make the text bigger, and hold the screen further away from your eyes. Also, don't use your phone too much! If it's been a while, let your eyes have a rest. So be smart about how you use your mobile devices and look after your eyes to ensure that your vision is protected.
