Technologically speaking, we've come far in the last couple of years and now, it seems difficult to find someone not on a smartphone. In truth, these devices are wonderful, because they let us be in touch with whoever we want whenever we need to be. However as handheld devices are made with 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 whole lot of demands on your vision that force your eyes to operate in a different way than they usually do when you read regular small print.
Because people tend to hold smart phones so close, the eyes need to work much harder to focus on text and images. This can lead to problems, particularly for those that use glasses or contact lenses. Some research shows evidence that when such individuals 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.
But there are more symptoms that can arise. Holding your device too close can make you blink less, which can lead to dry 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 eyestrain and blurred vision resulting from the use of handheld devices, we recommend keeping your phone at a safe distance from your eyes, and make the text a little bigger, so you can still read it. It's also important to try and regularly take breaks from staring at your phone. We all need technology, but it's crucial to be smart about it, in order to protect our vision.
