Few people spend 9 hours playing badminton because the arms are very tired; but many people spend 9 hours a day staring at the monitor screen. This may sound a bit exaggerated, but you may spend more time on your computer or mobile phone than you think: two surveys in 2016 found that adults watch the screen for about 9 hours a day, which is at least your waking time. Half of it. The result is that you may have a headache, dry eyes or blurred vision. So how do you prevent this from happening as more and more of your work and personal life has to be spent on the screen?

　　Why does the screen cause eye strain?

　　According to Dr. Purnima S. Patel, clinical spokesperson for the American Academy of Ophthalmology, "some people's discomfort after seeing the screen is likely to be eye strain. Most of us have fewer blinks when we look at the screen, causing eye strain and dry eyes. Reading books for a long time can also make your eyes tired, but the blue light emitted from the screen will make the problem worse. Usually the letters on the computer or mobile device are not precise or clear, the contrast between letters and background will be reduced, and the glare and reflection on the screen will be reduced. It may make viewing difficult. These will irritate our eyes.

　　How to reduce the damage of the screen blue to the eyes?

　　The best thing you can do so far is to remove your eyes from the screen. Every 20 minutes, turn your eyes to see objects at least 20 feet away for at least 20 seconds. Reduce the screen brightness to a comfortable level. If your screen is prone to glare, you can use an anti-glare screen protector to reduce reflected light. Also, make sure you don't get too close to your computer. The top of the computer screen should be under the eyes, about the length of one arm from your face.

　　Eye fatigue caused by blue light is not the only problem caused by the screen. They also disrupt your sleep, which affects your body's circadian rhythm. During the day, Blu-ray will wake us up and stimulate us, but late at night, too much light from the phone and tablet screen will make it harder for you to fall asleep.
