    Blink as usual

    Blinking your eyes as usual is recommended when you are using a laptop, but this also applies to smartphones. Looking at a screen for a long time makes the eyes become dry, and the natural way to moisten them is blinking. This reduces the negative effects of radiation from the screen. If necessary, use eye drops.

    The 20/20/20 rule

    Human eyes are not designed to stare at short distances, but alternate long and short ones. When looking at something close for hours, including reading, you are forcing your eyes to work unnaturally.

    The “20/20/20” rule means that every 20 minutes, you should look at something at least 20 feet away for at least 20 seconds. After looking at your smartphone for 40-50 minutes, take your eyes off it for 10-15 minutes.

    Brightness, contrast and font size

    Brightness, contrast and font size are the three aspects of smartphones that affect the eyes most. Too high or too low brightness and contrast are harmful. Adjust them to best suit your eyes, or use an application to adjust them automatically. Also, don't use the smartphone for too long in low light conditions, and never stare at the screen in the dark.

    For the font size, do not decrease it too much as this causes the eyestrain and reduces the viewing distance. In general, a larger font size is better.

    Keep the screen clean

    Flicking fingers on the screen constantly will leave many fingerprints. These stains not only look dirty, but also increase the pressure on the eyes. Use a piece of soft cloth to wipe the screen regularly.

    Keep your eyes at a correct distance

    For the same reason, avoid looking at smartphones too closely. If possible, keep the device 400-450 mm away from your eyes, as this is considered the ideal distance.
