Lately, it seems challenging to find someone who doesn't own some sort of smartphone. Tablets and smartphones are super useful when we're on the go. However as these devices have little screens, most users usually hold their iPads and iPhones much closer than they would hold printed materials. This creates a whole lot of demands on your vision that require your eyes to operate in a different way than they usually do when you look at small text at near distances.
Small text and images require your eyes to work much harder just to see clearly. It won't come as a shock to know that this can create issues, not least if you already use 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. Eventually, these challenges can result in eyestrain and headaches.
There are other symptoms that can arise from holding your device too close to your eyes, including dry eyes or blurry vision, which can result from staring at your screen for too long, which reduces how much you blink.
What can we do keep our eyes strong, while still using our phones? In order to prevent these symptoms resulting from the use of our phones, as eye care professionals, we recommend keeping your phone at a safe distance from your eyes, and make the text a little bigger, so you can still read it. It's also helpful to remember to regularly give yourself a break from staring at your phone. You've only got one pair of eyes. Treat them well.
