Have a look around- you are likely to realize that almost everyone is texting, playing on, surfing and even working from their mobile devices. Smart phones, tablets and handheld devices ensure our access to our friends, family and work no matter where we find ourselves. Nevertheless most people hold their handheld devices very close to their faces. Reading off the small screens that these devices feature can actually create a whole set of challenges for your vision.
Because we all hold smart phones so close, the eyes need to work much harder to look at text and images. Eventually, this has been found to lead to difficulty with focus and vision, especially if you already use vision correction, like glasses or lenses. Some research shows evidence that when people who wear glasses spend significant amounts of time holding a device at a closer than normal distance, the eyes have a rough time correcting for distance. This puts strain on your eyes, and you end up with headaches or migraines, which aren't pleasant.
Also, a lot of screen time can make you blink less, and that can lead to dry eyes and blurry vision.
In order to stop eyestrain and blurred vision resulting from the use of our phones, it's best to set your phone to display all text in a larger font, and hold the screen further away from your face. It's also recommended to work towards using your phone for less time, and letting your eyes have regular breaks. And after that, if you still experience headaches, you might need glasses to help you focus up close. Learning to be smart about your smartphone will protect your eyes.
