These days, it seems hard to find someone who isn't on a mobile device. We can't deny that these devices are wonderful, because they allow us to be connected almost always. However many people tend to hold their handheld devices very close to their faces. This gives way to a whole lot of visual demands that make your eyes function in a different way than they usually do to look at regular small print.
Small text and images make your eyes work much harder in order to focus. Over time, this has been found to lead to difficulty with focus and vision, especially if you already use vision correction, like glasses or lenses. If you already wear glasses, holding your phone or tablet too close can make it a real challenge for your eyes to correct for distance. When your eyes work too hard, it generally leaves you with unpleasant headaches as a result of the eyestrain.
But that's not all. Holding your device too close can make you blink less, and this can dry your eyes and make it harder to see clearly.
But we can't all just stop using our phones. So what's the solution? In order to prevent eyestrain and blurred vision caused by our phones, it is recommended to make the text on your device as big as possible and try to keep your phone as far from your eyes as you can. And try not to use your phone too much! If it's been a while, allow your eyes to have a little time away from the screen. So be smart about how you use your mobile devices and look after your eyes to ensure that your vision is protected.
