The weather is dry, how to deal with dry eye?

Dry eye refers to a variety of diseases with abnormal tear quality or quantity or dynamics, which leads to the decline of tear film stability, accompanied by eye discomfort and/or ocular surface tissue lesions. Also known as keratoconjunctivitis sicca. Common symptoms include dry eyes, easy fatigue, itchy eyes, foreign body sensation, burning sensation, sticky secretions, fear of wind, photophobia and sensitivity to external stimuli; Sometimes the eyes are too dry and the basic tears are insufficient, but it stimulates the secretion of reflective tears, leading to frequent tears; In severe cases, the eyes will be red and swollen, keratinized, corneal epithelium will rupture, and silk adhesion will appear. This kind of injury can cause keratoconjunctival lesions and affect vision for a long time.

Dry eye is a chronic disease that needs long-term treatment. If dry eye is caused by excessive evaporation of tears caused by eyelid exposure, the timing of eyelid reconstruction should be grasped according to the condition.

1. local therapy

(1) Eliminate the inducement, avoid using the computer for a long time, and avoid exposure to air conditioners, smoke and dust environment and other incentives for dry eye; People with meibomian gland dysfunction should pay attention to cleaning eyelids and applying antibiotics.

(2) The replacement therapy of tear components should use autologous serum or artificial tears, and severe patients should try to use artificial tears without preservatives.

(3) In order to prolong the stay time of tears on the eye surface, wet room mirror, silicone eye mask and therapeutic contact lens can be equipped.

(4) Avoid taking other drugs that can reduce tear secretion, such as antihypertensive drugs, antidepressants and atropine analogues; Immunosuppressants or short-term topical hormones can be added to the types involved in immune factors; Surgical treatment, etc.

2. Systematic therapy

Mainly to improve the nutritional status of patients and prevent secondary infection. Eat foods rich in vitamin A, such as milk, eggs and vegetables containing carotene; Oral cod liver oil and so on. Patients with dry eye should eat more fresh vegetables and fruits and increase the intake of vitamins A, B, C and E. In order to prevent dry cornea, dry eyes and decreased vision, computer operators should eat more foods rich in vitamin A. 。

There is no effective treatment at present. In order to relieve the pain, you can often drop physiological saline, artificial tears or antibiotic eye ointment. Or use electrocautery to close the small tears and reduce the outflow of tears. Eyelid plasty is feasible for xerophthalmia caused by eyelid insufficiency.

Self-treatment means:

1. Hot compress the eyes in the morning and evening for 5- 10 minutes:

The water temperature should be as high as possible. Generally, I can barely stand the temperature and wring the towel dry.

Fold the hot towel twice according to the short side, the length can cover your eyes, and the width just covers your eyes and the surrounding acupoints. Moreover, after the temperature drops, the layer wrapped inside can be turned out to continue hot compress, which can improve efficiency.

Hot compress is my favorite treatment, which will quickly relieve all kinds of eye discomfort during this period, so you can apply hot compress 24 hours a day if you like.

2. Do eye exercises in the morning and evening:

You can also massage some acupoints of your eyes. I forgot the specific name. Anyway, pressing the acupoints directly above and below the eyes is the most comfortable. After doing eye exercises, the eyes will feel very comfortable, so I not only like to do it once in the morning and evening, but also once when I have nothing to do.

3. Drink plenty of water:

Be sure to drink plenty of water, especially when you get up in the morning. No matter what happens, drink a glass of water. I later tested that if I don't drink water in the morning, my eyes will be very dry that day. And I find that my eyes will react when I am thirsty, so I usually drink water when I feel thirsty. How can my eyes secrete tears without water?

4. Exercise more:

Running is the best way to exercise and think. Most importantly, running can exercise many parts of the whole body, enhance immunity and promote the recovery of one's own functions. And I don't know why tears will suddenly increase a lot when running, and I basically won't feel any symptoms of dry eye. Later, I judged that this may be because the accessory lacrimal gland was stimulated during running, which increased the secretion of tears for a short time. For a long time, the tear secretion function of accessory lacrimal gland can be gradually restored with time. Pure personal guess. . .

5. How to yawn:

Sometimes when your eyes are particularly dry, you can yawn forcibly to make your eyes wet with tears, but when dry eyes recover, you must get rid of the habit of yawning often, otherwise others will think, haha.

These are all my treatments, without any medication.
