​What's the matter with itchy eyes and feeling like there is something foreign?

Eyes are the human body's visual organs. We recognize everything through our eyes. Under normal circumstances, our eyes are moist. If our eyes are dry and itchy, it proves that our eyes are not in a healthy state. If adults have itchy eyes and feel that there is a foreign object, it is usually due to excessive use of the eyes. If children feel itchy eyes and there is a foreign object, it may be that foreign objects have entered their eyes while they were playing. So today, let's take a look at why the eyes are itchy and there is a foreign object.

Do your eyes tend to be dry and itchy? This could be a symptom of dry eye syndrome. Pay attention to your eyes and supplement them with more nutrients that are good for the eyes on a daily basis.

1. Blink more: People always like to use "not blinking at all" to describe someone's concentration, but they don't know that the less you blink, the more likely you are to develop dry eyes. Because blinking helps the secretion and distribution of tears, fewer blinks directly lead to a decrease in the amount of tears. The tear film exposed to the air will evaporate quickly and lose its protective power to the eyeball. Therefore, prolonged use of the eyes, such as operating a computer, driving, reading, etc., can cause dry eyes.

Blinking is a protective nerve reflex action, and the tear layer can evenly apply tears to the surface of the cornea and conjunctiva to keep them moistened and not dry. A normal person blinks about 20 times per minute.

2. Pay attention to eyelid hygiene, wash your hands frequently, and do not rub your eyes with your hands, especially during the current high incidence season of infectious diseases such as influenza A (H1N1) and acute conjunctivitis. Hands can serve as a medium to spread germs.

Take a break after using your eyes for about an hour, close your eyes, look into the distance, or look at green plants or pictures. For patients with debris or loose material on their eyelids, it is important to maintain eyelid hygiene.

3. Young people who use computers for long periods of time should be aware of symptoms of dry eyes and seek medical attention as soon as possible. People over 40 are better off using bifocal lenses, or wearing glasses with lower degrees when typing.

Try to keep the distance from the computer at least 60 cm, so that your line of sight can be kept downward at about 30 degrees. This can relax the neck muscles and minimize the area of ​​the eye surface exposed to the air.

People who work on computers for a long time should eat more fresh vegetables and fruits, and increase their intake of vitamins A, B1, C and E. To prevent dry cornea, dry eyes, decreased vision, and even night blindness, you should eat more foods rich in vitamin A, such as soy products, fish, milk, walnuts, green vegetables, cabbage, water spinach, tomatoes and fresh fruits. Vitamin C can effectively inhibit cell oxidation.

The main functions of vitamin E are: lowering cholesterol, removing waste from the body, and preventing cataracts. Walnuts and peanuts are rich in vitamin E. Vitamin B1 can nourish the nerves, and green leafy vegetables contain a lot of vitamin B1. You can drink green tea or chrysanthemum tea appropriately every day, because the lipopolysaccharide in tea can improve the body's hematopoietic function, and tea also has the function of preventing radiation damage.

4. It is recommended to wear contact lenses. Wearing contact lenses for a long time will reduce tear secretion, so people who wear contact lenses will always feel dry eyes. To prevent dry eyes, it is recommended to wear contact lenses.

5. Try to use air conditioning as little as possible. In addition to regulating the temperature, air conditioning can also dehumidify and reduce the moisture content in the air. In this dry environment, the evaporation rate of the tear film increases, which can easily cause the eyes to become dry and astringent.

Winter, with its dry climate, is a high incidence season for dry eyes. In summer, the weather is hot. To prevent dry eyes, be sure to open windows and ventilate regularly when using air conditioning.

6. Apply artificial tears (nutrient solution) as needed, but be careful not to apply too frequently, preferably no more than 6 times a day. Because if you do it more than 6 times a day, it will wash away the normal tear film and aggravate the symptoms.

7. Gel eye ointment can be stored in the eye for a long time, but the ointment is greasy, patients feel it is not "hygienic", there is significant blurred vision, and the acceptance is poor. Eye gel is currently an ideal preparation. Eye gel has a long retention time in the eye, is very hygienic, has a cool feeling when applied, is easy to use, and has good acceptance.

8. To clean the eyelids and apply hot compress, use a towel dipped in water that is higher than body temperature but not too hot, and apply it on the eyes with closed eyes. Do this for about 10 minutes each time. It is best to do it once in the morning, because the meibomian glands secrete most vigorously at night, and the retained secretions are the most. Hot compress can help discharge the retained secretions. You can do it several times a day, the effect is very good.

9. For patients with moderate to severe disease who need artificial tears 4 to 5 times a day, the blockage of the tear duct can alleviate symptoms and reduce the amount of artificial tears used. Placing collagen plugs in the upper and lower tear ducts can achieve the effect of temporarily blocking the tear puncta.

10. Traditional Chinese medicine treatment is generally oral or topical application of Chinese medicine that clears heat, nourishes yin, promotes fluid and moistens dryness, which can treat dry eyes.
