Cause of dry eye
Dry eye syndrome threatens modern people’s eye health
The main cause of dry eye is Dry indoor environments, close work using computers, smartphones, etc., wearing soft lenses, etc.There is this. In addition, the cause of dry eye syndrome is that the use of various types of cold and hot air blowers dries out the tears, and when using computers and smartphones, eye blinking decreases and tear secretion decreases.
Children and teenagers use many electronic devices such as games, computers, and cell phones and overwork their eyes, which causes the skin muscles around the eyes to harden. In particular, children strain the eyelids above their eyes, causing tears to appear at both ends of the upper eyelids. Because the glands are blocked and tears cannot come out (dry eye syndrome), the eyes deteriorate and dry eyes occur.
In addition, after the age of 40, tear secretion decreases, which can cause dry eyes. In particular, menopausal women require detailed management as tear production decreases as female hormones decrease.
Fine dust / dust / electronic equipment, etc.
We live in an era of “snow” emergency.
As of 2014, 92% of the world's population was found to be living in areas that exceed air pollution limits set by the World Health Organization (WHO).
Fine dust causes physical irritation and a minimal inflammatory response when it comes into direct contact with the skin, mucous membranes of the eyes, nose, or throat, which are the body's primary defense shield.

The typical side effects of eye surgery such as LASIK and cataracts are
Dry eye syndrome occurs only in different degrees.
Dry eye after LASIK surgery occurs when the corneal sensory nerves that control tear secretion are damaged when the cornea is removed with a laser, resulting in decreased tear secretion and unstable tear film.
What is fine dust?
Particulate matter that floats or scatters in the air is called dust, and among these, dust with very small particle size is called dust. Particulate matter (PM)It is said that Fine dust is one of the representative air pollutants. Depending on the particle size, it is divided into fine dust with a diameter of 10㎛ or less (PM10) and fine dust with a diameter of 2.5㎛ or less (PM2.5). Depending on the source, fine dust is divided into artificial sources and natural sources such as yellow dust. The most representative artificial sources are automobile exhaust gases and workplaces (e.g. cement-related industries, metal manufacturing, construction, scrap metal, grain, wood and ore handling facilities). etc.), there is flying dust emitted from the air.
Fine dust consists of various types of substances depending on the source, but caution must be taken as it may be more harmful to health if it contains large amounts of heavy metals, sulfur dioxide, nitrogen dioxide, etc. Yellow dust refers to a phenomenon in which dust, mainly found in the deserts of Northern China or Mongolia, rises into the atmosphere, is carried far away by westerly winds, and slowly sinks. In Korea, yellow dust mainly occurs during the dry spring season, when the concentration of fine dust in the air becomes very high. Recently, as desertification in these areas and industrialization in China have accelerated, yellow dust has become more frequent and fine dust contains many harmful substances, raising public health concerns.

Various other causes
01
Aging
Dry eye syndrome occurs at age 40 years or older. Aging is the most common cause of dry eye syndrome. The normal aging process reduces the amount of tear secreted and changes the state of tears.
02
Accompanying disease
If you have diseases such as rheumatoid arthritis, Sjögren's syndrome (a rheumatic disease that causes inflammation or dryness of mucous membranes throughout the body, including the mouth and eyes), lupus, scleroderma, diabetes, and vitamin A deficiency, tear production is reduced.
03
Decreased sensitivity of cornea
Neurotrophic keratitis, which causes numbness of the cornea, or long-term use of contact lenses, which causes numbness of the eye surface, reduces tear production.
04
Excessive evaporation of tears
If the fat glands in the eyelids are inflamed or blocked by germs, the secretion of lipids is reduced, and when the fat is reduced, the tears of the water component evaporate easily.
05
Chronic conjunctivitis
If the goblet cells that act as mucous glands in the conjunctiva are reduced to chronic inflammation, the amount of mucous secretion is reduced and the water can not be held in the mucous layer, so the aqueous tear film will soon flow into the nasal cavity through the eye tube.
06
Thyroid disease
In hyperthyroidism, the eyes may grow so excessively that the tears may evaporate or the thyroid function may decrease and the tear production may be reduced.
07
Female hormone reduction
Reduction of female hormones during menopause reduces tear production.
08
Taking medication
Tears can dry out by drugs that reduce tear production. These include antibiotics, antihistamines, diuretics, antidiarrheals, parasympathetic blockers such as scopolamine, beta blockers to treat hypertension, sleeping pills, birth control pills, some acne remedies, some antidepressants, and some anesthetics.
09
Environmental factor
If the surrounding environment is dry, the eyes are stimulated by smoke or dust stimulation, sunburn, wind, etc., or if the number of blinks is reduced unconsciously during reading or computer operation, dry eye syndrome is likely to occur.
10
Chronic fatigue
Chronic fatigue, social stress, and hormonal changes caused by nutritional imbalance can also cause dry eye syndrome.
