"As autumn comes, the eyes are always dry and itchy and burning." "Every day I get up, I feel my eyes dry and grinding, and my eyes are particularly red after washing my face." "If you look at your phone for more than ten minutes, your eyes will swell and cry, which is very uncomfortable." ... Beijing Elderly Hospital Deputy Chief Physician of the Ophthalmology Department, introduced that in recent times, the number of patients who have come to the ophthalmology department for discomfort has increased. After diagnosis by the doctor, they are all troubled by "dry eyes". What causes dry eyes? How to prevent dry eyes?
Dry eyes are chronic eye surface disease
The climate in autumn is dry, the elderly pay attention to moisturizing the lungs, and young people pay attention to moisturizing the skin, but often ignore the eyes and prevent "drying". According to the "2021 Eye Health and Dry Eye Popular Science Report", the prevalence of dry eye in my country is as high as 21%-30%, which means at least 1 in every 5 people suffer from dry eye disease. Especially in dry autumn and winter, tears evaporate too quickly, and seasonal dry eyes are prone to worsening symptoms.
In medicine, dry eyes are chronic ocular surface diseases caused by multiple factors. They are instability of tear film or imbalance of the ocular surface microenvironment caused by abnormal quality, quantity and kinetics of tears. They may be accompanied by inflammatory reactions in the ocular surface, tissue damage and nerve abnormalities, resulting in a variety of discomfort symptoms and (or) visual dysfunction in the eye.
7 The main factor is the cause of the disease
There are 7 situations that may lead to dry eyes.
1. Systemic factors Many systemic diseases, especially immune system diseases and endocrine system imbalances can lead to dry eyes, such as diabetes , gout, various connective tissue , collagen vascular disease, abnormal thyroid function and other diseases.
2. Local factors of the eye include infectious conjunctivitis, allergic conjunctivitis, blepharitis , and abnormal eyelid margin structure.
3. Environmental factors include air pollution, light pollution, rays, high altitude, low humidity and strong wind.
4. Lifestyle-related factors such as long-term operation of video terminals (computers, mobile phones, etc.), less outdoor activities, long-term close-range plane fixation, lack of sleep, smoking, long-term wearing of corneal contact lens , eye makeup and long-term driving, etc.
5. Surgery-related factors The incidence of dry eyes is higher due to laser corneal refractive surgery.
6. Drug-related factors include systemic and local medication. Systemic medications: such as taking antidepressant, antihistamine, anticholinergic drugs, antipsychotic drugs, and systemic chemotherapy drugs; topical medications: such as taking antiviral drugs, antiglaucoma drugs and eye drops containing preservatives, etc.
7. Other factors such as anxiety, depression and other emotions can also lead to dry eyes.
Use the computer for at least 5 minutes for 1 hour and you should rest for at least 5 minutes
to prevent dry eyes. First of all, use your eyes reasonably.
reduces the use time of electronic devices such as mobile phones and computers. If you need to use the computer for a long time, you must ensure that you have a rest of at least 5-10 minutes every 1 hour. When using a computer, you should pay attention to adjusting the distance and position of the monitor and the eyes. It is recommended to have a distance of 50-70 cm, which is slightly lower than the eye level line by 10-20 cm. It is advisable to adjust the brightness of the monitor to half of the maximum brightness.
followed by diet adjustment.
Pay attention to maintaining a scientific dietary structure, balanced nutrition, drink more water and eat more fruits and vegetables, appropriately increase the proportion of foods such as soy products, fish, milk, eggs, carrots, etc. in the diet, and pay attention to supplementing vitamins.
The third is to increase humidity.
When working in an air-conditioning environment for a long time or using the eyes with high intensity, the frequency of flickering is reduced and the increase in tears evaporation can induce dry eye symptoms. Therefore, this type of people should pay attention to blinking more often, so that tears can be applied evenly on the surface of the cornea and conjunctiva, reducing the water on the surface of the eyeball to evaporate too quickly, and appropriate eye drops can be used to moisturize the eyes. In the dry season, take some moisturizing measures, such as regular spraying of water in the room or using a humidifier, etc.
The fourth is to pay attention to daily eye care.
Try to participate in outdoor activities as much as possible, and take appropriate rest when you feel eye fatigue. You can do eye exercises .
Fifth, active treatment of primary diseases that can cause dry eyes. For example, good blood sugar control in patients with diabetes and standardized treatment of connective tissue disease patients are conducive to relieving dry eyes symptoms.In addition, actively treating eye diseases such as infectious conjunctivitis and allergic conjunctivitis can also help relieve dry eyes by eliminating the primary disease.
It should be noted that once symptoms such as dry eyes appear, you need to seek medical treatment in time, make a clear diagnosis, and actively treat it to maintain our eye health.
