Look around and you will probably discover that almost everyone is texting, playing on, surfing and even working from their mobile devices. Tablets and smartphones are so convenient when it comes to being in touch when we're on the move. However because handheld devices are made with small screens, most users usually hold their smartphones much closer to their eyes than they would hold printed materials. Reading off handheld devices can actually lead to a whole set of demands for your eyes.
It's much harder for your eyes to focus on the small images and text you see on the small screens of smartphones. Over time, this has been found to cause difficulty with focus and vision, especially for those who already wear glasses. If you already wear glasses, holding a device too close can make it a real challenge for your eyes to correct for distance. When your eyes are under unnecessary pressure, it generally leads to painful 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 blurred vision and dry eyes, because excessive screen time reduces your blink rate.
What can we do keep our eyes strong, while still using our phones? In order to prevent these symptoms resulting from the use of handheld devices, as eye care professionals, we recommend that you hold the phone further away, and make the text a little bigger, 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. So be responsible about the way you use your smart phone and care for your eyes to ensure you protect your vision.
