Text (1): relieving “visual fatigue” in front of the computer
The eyes are dry and itchy, have a burning hot feeling, things are fuzzy and with teary eyes, often have a headache and the neck is aching. This is likely to be the “visual fatigue” that comes with looking at a computer screen for a long time.
Visual fatigue is a sub-healthy state of the eyes, which can be relieved after a general rest. However, if it lasts for a long time, it may become a chronic eye disease and even cause retinal detachment, blindness, etc.
The following several methods can alleviate computer-induced visual fatigue.
Position the screen correctly. The distance between eyes and screen should be kept at more than 60cm. The screen should be properly lowered so that the eyes can look down at the screen at 30 degrees. Thus not only not resting the eyes, but also relaxing the muscles of the neck and improving the blood supply to the brain.
Arrange a “half-time”. After working in front of the computer for 1 or 2 hours, be sure to let your eyes relax for about 15 minutes and look at other things outside the computer screen, such as other objects on the table and green plants outside the window.
Relax the eye muscles. Relax your whole body, put your elbows on the table, hold your eyebrows in your hands, close your eyes, and take a deep breath for 15–30 seconds. Repeat several times a day, this can alleviate eye muscle tension and reduce eye fatigue.
Eat properly and supplement your nutrition. Eat more vegetables and fruits, such as carrots, tomatoes, oranges, bananas, etc. In addition, drinking a few cups of green tea every day can not only protect and improve vision, but also reduce the harm of computer radiation.
