Technologically speaking, we've really progressed in the last couple of years and now, it would be difficult to find someone who doesn't own some sort of mobile device. Smart phones, tablets and handheld devices ensure our constant access to our email, text messages and the Internet no matter where we are. However a lot of people hold their handheld devices right in front of their faces. Reading off the small screens that these devices feature can actually create a whole set of demands for your vision.
Small text and images require your eyes to work much harder in order to focus. This might lead to problems, especially for people who already have vision correction such as glasses or contact lenses. If you already wear glasses, holding a device too close can make it even harder for your eyes to correct for distance. When your eyes are under unnecessary pressure, it generally results in unpleasant headaches or migraines as a result of the eyestrain.
There are more symptoms that can be caused by these habits, including dry eyes or blurry vision, which can result from staring at your screen for too long, which lessens your blink rate.
But we can't all just stop using our phones. So what's the solution? In order to lessen these symptoms caused by our smartphones and tablets, it's best to set your phone to display all text in a larger font, and keep the screen further away from your face. Also, try not to use your phone for too much time at once! If it's been a while, let your eyes have a little time away from the screen. If you still experience eyestrain, you might be far-sighted, and need glasses to fix that. Come see us for an exam, if this is something you're concerned about. We all need technology, but it's crucial to be smart about it, in order to help preserve our vision.
