Technologically speaking, we've really progressed in the past few years and now, it seems difficult to find someone not on some sort of smartphone. It's hard to avoid the fact that these devices are wonderful, because they let us stay in touch with whoever we want no matter where we are. Nevertheless a lot of people tend to hold their handheld devices right in front of their faces. Reading off handheld devices can actually lead to a whole set of demands for your eyes.
Small text and images make your eyes work much harder just to focus properly. Eventually, this has been found to cause problems with focus and vision, especially for those who already use vision correction, like glasses or lenses. Specialists say that when such individuals spend significant amounts of time with their phone at a closer than normal distance, the eyes have difficulty correcting for distance. Sooner or later, these difficulties can result in eyestrain and headaches.
But that's not all. Holding your screen too close can make you blink less, which can dry your eyes and blurry vision.
In order to stop eyestrain and blurred vision caused by 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. Also, try not to use your phone for too much time at once! If it's been a while, allow your eyes to have a rest. If you still experience headaches, you might have presbyopia, and need glasses to fix that. Come see us for an exam, if this is something you're concerned about. So be responsible about the way you use your smart phone and look after your eyes to ensure you protect your vision.
