Technologically, we've really progressed in the past few years and now, it would be challenging to find someone not on some sort of smartphone. Tablets and smartphones are extremely convenient when we're on the go. Nevertheless as these devices have little screens, many people tend to hold their smartphones a lot closer to their eyes than they would hold newspapers and books. This creates a whole lot of visual demands that make your eyes function in a way that's different to its normal activity.
Small text and images make your eyes work much harder just to focus properly. Not surprisingly, this might create issues, particularly for people who already have vision correction such as 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. Sooner or later, these difficulties can lead to eyestrain and headaches.
But that's not all. Holding your screen too close can make you blink less, and this can dry your eyes and blurry vision.
What can we do keep our eyes strong, while still using our phones? In order to prevent these symptoms caused by our phones, it's best to make the text bigger, and keep the screen further away from your eyes. It's also important to try and regularly give yourself a rest from staring at your phone. And after that, if you still experience eyestrain, it might be time for glasses to help you focus up close. So be responsible about the way you use your smart phone and look after your eyes to ensure you protect your vision.
