Staring at the tiny smartphone screen for hours can cause eye strain at best and irreversible eye damage at worst. Although it is difficult to imagine life without a smartphone, there is no need to sacrifice your eyes (they will definitely be needed later), because there are some effective ways to minimize the risks associated with the use of phones. Here are a few of them.
1. Get anti-glare protection.
Most mid- and high-end smartphones come with an anti-glare screen by default, but if yours isn't, install it immediately. Anti-glare screens are not expensive, but they can make a drastic difference because they reduce the amount of blue light that reaches your eyes.
If you don't want to change the whole screen to a new one, the next best thing is the app. For example, Bluelight Filter for Eye Care for Android also reduces the amount of blue light, but is not as effective as a separate anti-glare screen.
2. Blink frequently / moisturize your eyes with drops.
Frequent blinking is recommended when using a desktop computer, but for smartphones this is even more important. Looking at the screen dries the eyes, and the natural way to moisturize them is to blink. This reduces the negative effects of screen radiation.
3. Follow the 20/20/20 rule.
Human eyes are not made for prolonged gazing at close objects. Therefore, when you watch something at close range for hours, even if it's just reading a book, you force your eyes to behave unnaturally. In the case of smartphones, the so-called rule 20/20/20. Essentially, this means that you have to look at something at least twenty centimeters away for at least twenty seconds every twenty minutes.
Even better, after every forty or fifty minutes spent with the device, take a break of ten or fifteen minutes from the screen. If you are not too lazy, you can even work out a little - this will help not only your eyes, but also your general condition.
4. Adjust brightness, contrast and text size.
Brightness, contrast and text size are the three aspects of the smartphone that most affect your eyesight. Brightness and contrast that are too high or too low are harmful to the eyes. You can use common sense to set them, or you can use the application to automatically adjust the brightness.
It will also help to avoid prolonged use of smartphones in low light environments. Never look at the screen in the dark. As for the size of the text, it should not be reduced, because it strains the eyes and reduces the viewing distance. In general, larger text is better, although scrolling to see everything on the page is certainly annoying.
5. Keep the screen clean.
No wonder there are a lot of dirty marks on the screen. This dirt is not only unhygienic but also puts a strain on the eyes. Just take a soft cloth and clean the screen regularly.
6. Keep the right distance.
Another common reason why your eyes hate your smartphone is to hold it too close to your eyes. If possible, try to keep the device at a distance of more than 40 centimeters, as this is considered the optimal distance.
