Self-treatment of dry eye, people who are often tired of eyes are office workers. This is mainly because office workers need to face the computer all day, so they often feel tired eyes. So, let's share the self-treatment methods of dry eye.
Self-treatment of dry eye 1 1, try to avoid touching your eyes with your hands.
When the eyes are dry, many people's first reaction is to gently touch their eyes with their hands, thus achieving the purpose of relieving dryness and itching. In fact, this is often counterproductive. Although it temporarily relieves the dryness of the eyes, touching the eyes with hands also brings a lot of germs into the eyes, which causes eye inflammation such as keratitis.
2. Choose appropriate eye drops
Eye drops specially used to relieve eye fatigue should be used to moisten eyes, but the ingredients of eye drops are different and the symptoms are different, so don't choose blindly.
3, prevention first
Dry eye can also be prevented. If you pay attention to eye hygiene, keep your eyes at a certain distance from the computer or books (the specific distance is related to the size of the computer screen or books). People who wear contact lenses had better wear frames when working or surfing the Internet to keep their eyes moist. In addition, the study found that frequent complete blinking can moisturize the eyes. Eating more fruits or foods containing antioxidants such as vitamins A, C and E will help the normal secretion of sebaceous glands.
4. Actively treat eye diseases
We should actively treat diseases on the surface of the eyeball. Trachoma, chronic conjunctivitis or blepharitis can easily scar the conjunctiva of eyes, destroy corneal epithelial cells and tear-secreting cells, and finally form dry eye.

However, if you have sticky white filamentous secretion, accompanied by symptoms such as foreign body sensation and itchy eyes, you need to be alert to dry eye.
Step 3 blow
I used to love walking in the wind, and the feeling of the wind blowing on my face was so cool; Now I am afraid of blowing, even if I walk in the wind, I have to squint or close my eyes, and there are still many scenery to miss.
In addition, in addition to dryness and burning sensation, the eyes often have foreign body sensation, fear of light and smoke, loyalty, itchy eyes, fatigue, vision fluctuation or blurred vision, and increased eye secretions. In severe cases, corneal softening and perforation will occur, and conjunctival congestion can be seen during examination.
Patients with dry eye have blurred vision, dry eyes and often blink consciously. Suffering from dry eye, the optic nerve ignores viologen, the dark adaptation time is prolonged, and finally becomes night blindness.
If vitamin A or carotene is not supplemented in time, the organs of the eyes will change, the conjunctiva of the eyes will be affected, and the lacrimal gland will stop secreting tears. Then the cells on the cornea keratinize and become turbid, forming ulcers, which eventually leads to corneal tissue rupture, even eye bleeding and oozing viscous liquid, which develops into keratomalacia and then makes the heel dark blind.
Methods of preventing dry eye
1, avoid "staring". Blink frequently, at least 4-5 times per minute.
2, to prevent dry eye, don't blow air conditioning for too long. Avoid airflow blowing on the seat, and place tea leaves near the seat to increase the humidity around.

It is the most common cause of dry eye angle; Congenital absence of lacrimal gland, senile hypofunction of lacrimal gland or some autoimmune diseases cause lacrimal gland inflammation, trauma, infection and autonomic nerve disorder. Long-term use of some eye drops or taking some drugs will cause insufficient tear secretion. People who wear contact lenses for a long time.
Undersecretion of mucin layer
Vitamin A 1 deficiency, chronic conjunctivitis, chemical burns, etc.
Excessive evaporation of tears, uneven distribution of tear film
Eyelid diseases lead to poor eyelid closure, reduced blinking times, and long-term stay in air-conditioned rooms or outdoor strong winds and hot environments.

Bananas are not only rich in potassium, so bananas can help us protect our eyes.

Causes of eye fatigue
1, eye refractive abnormality
When suffering from hyperopia, myopia, astigmatism and presbyopia, it takes a lot of adjustment to see the eyes far and near, which makes the eyes overworked.
2, eye fatigue symptoms, excessive use of eyes
When myopia is not corrected, the reading distance is too close, leading to excessive aggregation, which may be accompanied by excessive adjustment, aggravating the degree of myopia and making the reading distance closer. Such a vicious circle occurs, leading to eye fatigue. Constantly changing the focus: under the condition of astigmatism, when the image can't be at one point, it is necessary to use the adjustment function of the ciliary muscle in the eye to constantly change the focus and overuse the adjustment. Ciliary muscle is also related to the head nerve. Over time, the fatigue of ciliary muscles will lead to corresponding nerve pain.
3. Eye diseases
Suffering from eye diseases such as corneal cloud and lens opacity, blurred vision is also easy to cause eye fatigue.
4. Abnormal eye development
If the pupil distance between the eyes is large, it is difficult for the eyes to gather and eye fatigue is easy to occur.
5. Physical quality and life factors
For example, lack of exercise, malnutrition, frequent insomnia, irregular life, excessive alcohol and tobacco, and careless eye hygiene can easily lead to eye fatigue.
6. Age factor
People over 40 years old have aging eyes, but they don't have reading glasses in time, which is easy to get tired eyes.
7. Environmental factors
Insufficient lighting in the workplace or study place; The handwriting or work is too small; The difference between target and background is not clear; Reading, writing and working for a long time; The sight distance is not fixed (for example, reading, writing and working in cars and boats), which will cause eye fatigue, excessive use of adjustment force and eye overload, which will not only easily lead to eye fatigue, but also cause myopia and other diseases.
