While using the phone, we often tend to blink our eyes. Blinking eyes helps reduce dryness and irritation by keeping eyes moist and helps refocus eyes.
According to this rule, look away from the screen every 20 minutes, for 20 seconds at an object that is 20 feet away.
Check that your screen's brightness matches with the amount of light in the environment. Your eyes may suffer if your screen is too bright or too dark.
Make sure to clean your screen with a clean dry cloth from time to time. By doing this, you can be sure that all dirt, dust, and grime are removed from the phone's surface, improving visibility and lessening eye strain.
Most people keep their phones eight inches or less away from their face. Holding phone that close may damage the eyes. To prevent eyes from damage, keep a distance of 16 to 18 inches from the screen.
Enable night mode or reading mode to reduce blue light emission.
Take regular breaks from your phone to rest your eyes.
