Do you ever wonder about the effect your mobile device might be having on your sight? Handheld devices, like phones and tablets are super useful when we're on the move. However as these devices sport little screens, a lot of people tend to hold their smartphones a lot closer to their eyes than they hold books and magazines. This gives way to a whole lot of demands on your vision that make your eyes function in a different way than they usually do when you read small text at near distances.
It's a challenge for your eyes to focus on small images and text. After some time, research shows this may cause problems with focus and vision, especially if you already wear glasses. Some research shows evidence that when such individuals spend significant amounts of time holding a device at a closer than normal distance, the eyes have difficulty correcting for distance. Sooner or later, these difficulties can result in eyestrain and headaches.
In addition to this, too much time looking at your small screen can reduce your blink rate, and that can cause dry eyes and blurry vision.
In order to lessen these symptoms caused by our phones, as eye care professionals, we recommend keeping your phone at a safe distance from your eyes, and enlarge the text, so you can still read it. And don't use your phone too much! If you've been on it a while, allow your eyes to have a break. You've only got one pair of eyes. Look after them well.
