Myopic people become accomplices of younger electronic products

Abstract: when the eyes face the computer for a long time and are in the air-conditioned environment, it is easy to cause dry eyes. In addition, due to work tension, the number of eye blinks will be unconsciously reduced, which will affect the function of lacrimal gland and lead to dry eyes.

with the popularization of computers, the “window of the mind” is threatened by dry eye disease. Experts predict that the number of patients with dry eye disease will increase by 10% per year in the next five years. The doctor pointed out that dry eye is not just an eye symptom, but an eye disease. People should pay great attention to it, try to prevent it in daily life, and go to the hospital for examination in time.

in the ophthalmology clinic, one in five people suffers from dry eye, mostly computer workers, office workers and drivers. This is because the eyes face the computer for a long time and are in an air-conditioned environment, which is easy to cause dry eyes. In addition, due to work tension, the number of eye blinks will be unconsciously reduced, which will affect the function of lacrimal gland and lead to dry eyes. Most people blink 15 times per minute, read 10 times, operate the computer 4-5 times, and drive or play games only 2-3 times. If the number of blinks is reduced by 75%, the secretion of tears will be greatly reduced, and there will even be a risk of blindness.

causes of dry eye

sandstorm, dust, environmental pollution, long-term use of computers, wearing contact lenses Age, physiological factors (such as climacteric syndrome) and some eye diseases. Some anti allergic drugs, cold drugs and contraceptives also affect the production and composition of tears.

Dry eye is also known as dry conjunctival keratitis. Healthy eyes will naturally secrete tears to lubricate the eyes. If the environment is dry, long-term use of air conditioning and excessive use of the eyes will make the water in the eyes evaporate faster and aggravate the loss of tears. In this way, the cornea will not be wet, the whole eye is dry and dull, corneal epithelium is keratotic, there is obvious scar formation, and there will be blurred vision when looking at things, Eyes have burning sensation and foreign body sensation, visual fatigue, grinding pain, etc.

how to prevent and treat dry eye with computers

the most effective way to prevent dry eye is to maintain a regular life, get enough sleep and drink more water. However, when the nature of work cannot be changed, the best way is to blink with high frequency and integrity, avoid “staring”, let your eyes rest at least once every hour, and do eye exercises to help reduce eye fatigue. If you are a glasses family, you’d better not use contact lenses in front of the computer and wear frame glasses. The working posture and distance are also very important. It is recommended that the distance be 50 to 70 cm, and the fluorescent screen should be slightly lower than the horizontal position of the eye by 10 to 20 cm, forming a downward viewing angle of 15 to 20 degrees, so as to minimize the area of the eye surface exposed to the air. However, after working from the down angle for about an hour, you should also try to move your eyes to the left and right. The light of the surrounding environment should be soft. The brightness of the computer fluorescent screen can be adjusted to half of the maximum brightness, so as to see clearly but slightly darker than the surrounding objects. Many experts in

and

also believe that the occurrence of dry eye is related to the long-term lack of vitamin A. therefore, people who have been engaged in computer operation for a long time should also pay attention to dietary conditioning and eat more bean products, fish, milk, walnuts, green vegetables, Chinese cabbage, water spinach, tomatoes and fresh fruits.
