Nowadays, no matter learning or daily life, people are increasingly inseparable from electronic devices such as computers and mobile phones. The 'screen time' is getting longer and longer, eyes are increasingly damaged, and vision is blurred. A recent US study found that A major cause of object obfuscation is Computer Vision Syndrome (CVS). Prolonged use of computers, e-readers, and cell phones can easily cause visual fatigue, blurred vision, dry eyes and decreased vision, headache, and neck pain.
According to Bai Ji, chief ophthalmologist of Daping Hospital, Third Military Medical University, reducing the use of electronic equipment is the most sensible option for preventing eye fatigue and protecting eyesight. Use only when dealing with work. Don't play games for long periods of time. The ciliary muscle contracts when placed close to an object, which is prone to fatigue. For eyes that have long-term use, the 20-20-20 rule can be used to relax the eye properly: Rest every 20 minutes for 20 seconds, Look away from the screen, toward 20 feet (More than 6 meters) grass, green trees or other objects look out, do not blink or blink, and concentrate on staring and recognizing their outlines, so that the eyes are in an active process, which can play a role in adjusting the sensitivity.
We can also debug electronic equipment and environment. 1. Adjust the background color of the display to light apple green; 2. Adjust the position of the monitor to keep the height slightly lower than the eye level, that is, the top of the computer screen is 10~15 degrees lower than the line of sight. Left and right, the distance between the screen and the face is kept at 51~71cm. Make sure that when you look at the screen, you will not stretch your neck or fatigue your eyes; 3. Make the brightness of the display itself harmonize with the ambient light, such as when you play the phone at night. A small, soft light, with curtains to prevent the external light from causing the screen to glare, the computer screen to avoid the reflection of windows or overhead lights.
In addition, we can use physical therapy to relax our eyes. Frequent eye exercises help relieve eye dryness, such as turning the eyeball up and down, turning eyes open at least 20 times, rubbing the temples and other eye points. Hot compresses can also be used to improve blood supply to the eye. Relieve ciliary muscle tension: Immerse the towel in warm tea water and apply it to the eyes for 10-15 minutes. Rub your hands and heat. Cover your eyes with your palms. Don't press your eyes for 20 minutes a day. Wear anti-blue lenses. Blocks harmful blue light to the eye.
Although these methods can have effects on eye fatigue, soreness and other symptoms, for people with true myopia, people with longer axial lengths do not achieve the therapeutic effect. Therefore, if the eyes are repeatedly exposed to photophobia, tingling, tears and vision Obscure things, etc., should go to the hospital in time to do a comprehensive eye examination.
