Take a look around- you will probably realize that almost everyone is browsing, texting, clicking and playing on mobile devices. These devices guarantee that we have access to our friends, family and work no matter where we are. However because these devices have little screens, many users usually hold their iPads and iPhones much closer than they hold printed materials. This creates a number of visual demands that make your eyes function in a way that's different to its normal activity.
Small text and images require your eyes to work much harder just to focus properly. It won't come as a shock to know that this can cause problems, not least if you already use vision correction such as glasses or contact lenses. Researches claim that when such individuals spend significant amounts of time holding a device at a closer than normal distance, the eyes have an even harder time correcting for distance. When your eyes work too hard, it usually leaves you with painful headaches or migraines as a result of the eyestrain.
But there are more symptoms that can arise. Holding your device too close can make you blink less, and this can lead to dry eyes and make it harder to see clearly.
In order to prevent these symptoms resulting from the use of handheld devices, we recommend that you hold the phone further away, and enlarge the text, so you can still read it. Also, don't use your phone too much! If you've been on it a while, let your eyes have a rest. If you still experience headaches, you might need glasses specifically made to help you focus up close. You've only got one pair of eyes. Look after them well.
