Have a look around- you're likely to discover that almost everyone is browsing, texting, clicking and playing on mobile devices. We can't deny that these devices are wonderful, because they allow us to be connected almost always. Nevertheless as these devices have small screens, many people often hold their smartphones a lot closer to their eyes than they would hold printed materials. This creates a whole lot of visual demands that force your eyes to work in a different way than they usually do to look at regular small print.
Small text and images make your eyes work much harder just to focus properly. After some time, research shows this may lead to difficulty with focus and vision, especially if you already wear glasses. Specialists say that when people who wear glasses spend significant amounts of time with their phone at a closer than normal distance, the eyes have difficulty correcting for distance. Your eyes strain, and you wind up with headaches or migraines, which aren't pleasant.
But there are more symptoms that can arise. Holding your screen too close can make you blink less, which can dry your eyes and make it harder to see clearly.
But we can't all just stop using our phones. So what's the solution? In order to stop these symptoms caused by our phones, it's best to use a larger font, and hold the screen further away from your eyes. Also, don't use your phone too much! If you've been on it a while, allow your eyes to have a rest. And after that, if you still experience headaches, it might be time for glasses specifically made to help you focus up close. Being smart about your smartphone will protect your eyes.
