Miss Liu has been extremely distressed recently. In her twenties, she actually feels “dazzled”. At the same time, her eyes are dry and astringent, and she has a foreign body feeling. Eye drops do not work. According to the doctor’s diagnosis, she has dry eyes. As an office worker, she can’t leave her computer during the day. After work, she chases TV dramas with her tablet computer, and her eyes finally can’t stand it.
Sun ran, deputy chief ophthalmologist of Xuanwu Hospital, said that there are not a few patients like Miss Liu who have dry eyes, tears, blurred vision, myopia and blurred eyes due to excessive use of electronic products. Dr. Sun explained that excessive use of mobile phones, tablets and so on may induce dry eye, cataract, glaucoma, blurred eyes and other eye diseases. The ciliary muscles used by our eyes to adjust the distance are equivalent to the “zoom lens” of a camera. Looking at the close repeatedly will make it too tired to adjust, and people will feel eye pain, headache and blurred eyes. At the same time, because the font on the display screen is small and the screen keeps flashing, it will also aggravate the symptoms of blurred vision. Looking at electronic products in a dark environment, the screen flickers, and the contrast is very obvious, which is also easy to cause visual fatigue.
Moreover, whether it’s a mobile phone, iPad or computer, if you stare at the screen for a long time, the number of blinks will be unconsciously reduced. In addition, the air in northern China is dry, and the symptoms of eye pain and dryness will be more prominent. Some friends also like to lie down or lie down and look at their mobile phones. This kind of low head and close-up use of eyes makes the eyes in a forward “protruding” state for a long time, which is easy to induce “angle closure” glaucoma.
let’s take a look at the bad habits of using eyes:
1. Keep your hands on electronic products, brush your circle of friends and catch up with TV dramas anytime and anywhere.
2. When I look at my mobile phone on the bus or subway, the font size on the screen is too small, and the screen is very close to my eyes.
3. Watch your mobile phone and iPad before going to bed, especially after turning off the light for more than half an hour.
4. It is customary to brush the circle of friends lying down or lying on the bed.
5. When your eyes are tired, take out a drop of eye drops you bought casually.
Dr. Sun said that to stay away from eye diseases, we should start with good eye habits:
1. Try to avoid playing mobile phones on buses and subways. When the mobile phone shakes, the eyes need to constantly adjust the ciliary muscles to focus, which is easy to cause fatigue.
2. If you must look at your mobile phone before going to bed, you’d better turn on the headlights in the room and control the time within 10-20 minutes.
3. Let your eyes rest. When children play mobile phones and iPads at close range for 1 hour, the myopia degree will increase by 100 degrees, and the degree can recover after rest, which belongs to pseudomyopia. Young people need to rest for 10-15 minutes after using electronic products for 1 hour; The middle-aged and old people, especially those with eyesight or other eye diseases, should take a rest and relax after using electronic products for up to 20 minutes.
4. Do eye exercises or rotate your eyes to relax. Turning the eyes can not only exercise the muscles around the eyes, but also promote blood circulation.
5. Friends who are used to using eyedrops at ordinary times can use hot towels to apply heat to their eyes, or smoke their eyes with the hot gas released from hot tea to alleviate fatigue.
6. Eat more foods containing β- Vegetables and fruits rich in carotene and vitamin C, green leafy vegetables, carrots, tomatoes and other vegetables and fruits contain a large amount of β- Carotene, which can be converted into vitamin A after digestion, helps maintain the health of eyes and skin. Proper calcium supplementation can increase the hardness of the eyeball and delay the process of myopia. The proper supplement of fruits and vegetables rich in anthocyanins, such as blueberry, purple cabbage and purple potato, can increase the antioxidant capacity of the human body, protect the body from free radicals, and delay the development of cataract.
