Do you ever think about the effect your mobile device might be having on your sight? These devices guarantee our constant access to our email, text messages and the Internet wherever we find ourselves. Nevertheless as these devices have small screens, a lot of people tend to hold their iPads and iPhones much closer to their eyes than they hold books and magazines. If you do a lot of reading off small screens, it can really be a strain on your eyes.
Small text and images make your eyes work much harder just to focus properly. Eventually, this has been found to cause difficulty with focus and vision, especially for those who already wear glasses. Some research shows evidence that when people who wear glasses have a lot of small screen time, the eyes have difficulty correcting for distance. Your eyes strain, and you wind up with headaches or migraines, which aren't pleasant.
There are other symptoms that can result from these habits, including blurred vision and dry eyes, because excessive screen time lessens how much you blink.
In order to prevent eyestrain and blurred vision caused by handheld devices, it's best to make the text bigger, and keep the screen further away from your face. It's also a good idea to work towards using your device in shorter increments, and giving your eyes lots of rests. And after that, if you still experience eyestrain, you might need glasses specifically made to help you focus up close. We all need technology, but it's important to be smart about how we engage with it, in order to help preserve our vision.
