Have you ever thought about the effect your smartphone might be having on your vision? Smart phones, tablets and handheld devices ensure that we have access to our email, text messages and the Internet wherever we are. Nevertheless as handheld devices have small screens, a lot of users tend to hold their iPads and iPhones a lot closer than they would hold printed materials. This creates a number of demands on your vision that force your eyes to operate in a way that's quite a change from its normal activity.
Because people tend to hold smart phones so close, the eyes need to work much harder to focus on text and images. After some time, this has been found to cause difficulty with focus and vision, especially for those who already wear glasses. Specialists say that when people who wear glasses have a lot of small screen time, the eyes have difficulty correcting for distance. When your eyes are under unnecessary pressure, it usually results in painful headaches as a result of the eyestrain.
In addition to this, more screen time can reduce your blink rate, and that can lead to dry eyes and blurry vision.
In order to stop eyestrain and blurred vision caused by handheld devices, as eye care professionals, we recommend that you hold the phone further away, and enlarge the text, so you can still read it. It's also important to remember to regularly give yourself a break from staring at your phone. And after that, if you still experience headaches, you might need glasses specifically made to help you focus up close. We can't give up technology, but it's important to be smart about how we use it, in order to protect our vision.
