How does dry eye disease develop and what is dry eye disease?

Experts from Heze Guangming Eye Hospital explained: Due to the decrease in tears or the decline in tear gland function, it is a symptom of small scars in the eyes.

In the past, dry eye syndrome, cataracts, glaucoma and other diseases were mainly common eye diseases of the elderly, but now it is found that more and more young people and white-collar workers in some cities who are often exposed to computers, televisions, and game consoles are suffering from dry eye disease.

There is a layer of tears between the upper and lower eyelids of the person, which contains substances that protect the eyes from infection, and when people blink, the tears are evenly distributed in the eyeballs, and the dust on the conjunctiva of the eye is washed to keep the eyes bright. In general, tear secretion decreases with age, so the incidence of dry eye disease is higher in the elderly. There are quite a few factors that can trigger dry eyes, including:

Decreased tear secretion after middle-aged and elderly age, diseases of the eyes themselves, such as corneal degeneration, blepharitis, trachoma, etc.; Various immune diseases and connective tissue diseases, such as rheumatoid arthritis, lupus erythematosus, dry mouth and eyes, arthritic syndrome (mostly in middle-aged and elderly women), etc.; Caused by certain medications, such as birth control pills, sleeping pills, sedatives, cough medicines, stomach medicines, etc.; It can also be caused by vitamin A deficiency.

In recent years, the trend of dry eye disease is obvious, mainly due to the fact that in modern life, young people have more and more contact with TV and computers for work and entertainment, face fluorescent screens for a long time, and lack of timely blinking or resting eyes, which affects the tear secretion of both eyes. or long-term use of certain eye drops, such as vasoconstrictor eye drops, can also easily develop dry eye disease.

For how dry eye disease is caused by these causes, we must pay attention to the prevention and treatment of these dry eye diseases.

Not blinking for a long time is the main reason, for example, in front of the computer, you will unconsciously not blink for a long time.

Dry eye is a disease of the corners of the eye, also known as keratoconjunctivitis xerosa. It is a general term for a variety of diseases caused by abnormal tear quality or quantity or abnormal kinetics, resulting in decreased tear film stability, accompanied by ocular discomfort and/or ocular surface tissue lesions.

Pathological changes on the surface of the eye, such as conjunctival scarring caused by trachoma, can lead to the destruction and obstruction of lacrimal glands, accessory lacrimal glands, and goblet cells.

immune-based inflammatory responses, such as Sjögren's syndrome and apoptosis; Decreased levels of sex hormones, such as menopause in women, etc.

As well as the influence of external environmental factors, such as long-term use of computers and long-term exposure to air conditioning and smoke and dust, are the main factors for the occurrence of dry eye.

Dry eye syndrome is a condition in which tears are secreted less quickly than they evaporate. The most common cause is a decrease in the number of blinks or a decrease in tear production.

Coratoconjunctivitis sicca, also known as dry eye, refers to a variety of diseases caused by abnormal quality or quantity or kinetics of tears caused by any reason, resulting in decreased stability of the tear film, resulting in eye discomfort and ocular surface tissue lesions.

There are many causes of dry eye syndrome, such as eye diseases, systemic diseases or environmental factors, which can lead to the occurrence of the disease.

First, the main **.

1. Eye diseases: Suffering from eye diseases such as trachoma, blepharitis, and blepharitis may lead to the disease.

2. Systemic diseases: such as Sjögren's syndrome, rheumatoid arthritis, ankylosing spondylitis and other diseases can also cause dry eye syndrome.

3. Environmental factors: Being in a windy, dry or smoking environment will cause excessive evaporation of tears, which can cause dry eyes.

4. Age factor: With the increase of age, the body's tear secretion will decrease, which can cause dry eye syndrome.

5. Injury: Inflammation, radiation and other factors will cause damage to the lacrimal glands, which can cause dry eye syndrome.

6. Drug factors: such as antidepressants, birth control pills, acne, hypertension and other drugs will cause insufficient tear secretion, which can cause dry eyes.

2. Predisposing factors.

1. Gender factors: It is related to estrogen levels, and women are more likely to get sick when using birth control drugs and during menopause.

2. Dietary habits: People who are deficient in vitamin A for a long time are more likely to get this disease.

It is conjunctivitis, the production of tear glands is reduced, resulting in a lack of tears and a lack of vitamin A, so it will cause dry eye syndrome, in daily life should eat more fresh vegetables and fruits, it is best to use eyes scientifically, look less at electronic products, do not let the eyes too tired, but also to properly relieve their eyes, take a look at the green plants.

It may be because I often wear contact lenses, and I wear them for too long, and the usual cleaning is not in place.

It could also be that the environment is too dry, or you are engaged in computer operation and more delicate work.

The prolonged use of antibiotics causes dysbiosis.

Decreased tear quality due to lack of sleep due to too old age.

Blocked tear ducts, frequent mobile phone and TV, reading in dimly lit places, lack of vitamins, medications taken for reasons.

The cause of dry eye syndrome is because the function of the tear glands is deteriorating, and the body is overused and lacks vitamins and hormones, which can cause dry eye syndrome.
