  Secondly, dry eyes are also one of the common problems of smartphone users. Normally, the human eye keeps the surface of the eyeball moist by blinking, but staring at the mobile phone screen for a long time will reduce the frequency of blinking, resulting in dry eyes. Especially when using mobile phones to read, watch videos or play games, users are highly focused and blink less frequently, which causes insufficient lubrication on the surface of the eyeball and eventually leads to dry eyes.

  Effective ways to prevent and relieve eye problems

  Faced with the potential harm of smartphones to eye health, it is necessary for us to take some effective measures to prevent and alleviate these problems.

  First, controlling the time and frequency of using mobile phones is the key to protecting eye health. Experts suggest that adults should not use electronic screens for more than two hours a day, and teenagers should strictly control the use time. In addition, following the "20-20-20" principle, that is, every 20 minutes of using the phone, taking a 20-second break and looking 20 feet away can effectively relieve eye fatigue.

  Secondly, adjusting the brightness and contrast of the mobile phone screen is also an important measure to protect the eyes. The screen brightness should not be too high or too low, and should match the ambient light. Too high brightness will increase the burden on the eyes, while too low brightness will cause excessive eye strain. Proper adjustment of contrast can help reduce eye fatigue.

  Regular eye examinations and eye care measures are also important means to prevent eye diseases. Using eye drops or artificial tears can relieve dry eyes and keep the eyeballs moist. For people who use smartphones for a long time, it is particularly important to have regular vision tests to detect and deal with potential eye problems in a timely manner.
