Have a look around- you will probably realize that pretty much everybody is texting, playing on, surfing and even working from their mobile devices. We can't deny that these devices are wonderful, because they let us be connected almost always. However most people tend to hold their phones and tablets very close to their faces. This creates a whole lot of demands on your vision that force your eyes to operate in a way that's different to its normal activity.
Because we all hold smart phones so close, the eyes need to work much harder to look at text and images. This might cause problems, especially if you already use vision correction such as glasses or contact lenses. Any eye care professional will tell you that when such individuals spend a lot of time holding a device at a closer than normal distance, the eyes have difficulty correcting for distance. Sooner or later, these challenges can lead to eyestrain and headaches.
But that's not all. Holding your screen too close can make you blink less, which can lead to dry eyes and make it harder to see clearly.
What can we do keep our eyes strong, while still using our phones? In order to stop eyestrain and blurred vision resulting from the use of handheld devices, 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 good to try and frequently give yourself a rest from staring at your phone. If you still experience headaches, it might be time for glasses to help you focus up close. Learning to be smart about your smartphone will only protect your eyes.
