Why children and adults often blink their eyes

Often parents notice the rapid eye-blinking of small children. In adults, this is also common. What is the reason for this phenomenon? Aggravated twitching of the eyelids is observed with nervous diseases, metabolic disorders, and sometimes with the simple ingress of foreign bodies. What kind of diseases does this sign indicate? The article will tell about frequent blinking of eyes in children, causes, treatment of the disorder.

Causes of frequent blinking

Eyes - organs of vision, which are protected from external influences by eyelashes, as well as constantly evolving tear fluid. Periodic closing of the eyes prevents the eyeball from drying out. Causes of frequent blinking of eyes in children can act hormonal, nervous disorders, deficiency of vitamins and minerals. In adults, the symptom also indicates a pathology in the body.

Most probable causes:

1. Foreign body contact on the conjunctival mucosa or on the sclera.
2. A neurotic disorder is a nervous tic.
3. Dry eye syndrome.
4. Overstrain of the organs of vision.
5. Inflammatory diseases: conjunctivitis, iridocyclitis.

However, the most common cause of frequent eye blinking in children is the ingress of mote into the mucous membrane. At this moment the pain receptors become irritated, the person starts blinking, the teary fluid is released. This helps to remove foreign particles.

Find out why there are two in the eyes: causes, diagnosis, treatment.

Whether eye twitching refers to bulbar disorders and how to recognize pathology.

One of the reasons for the frequent twitching of the eyelid in adults and children is a nervous tic. This is the result of a nervous breakdown, manifested in the trembling of the eyelids. It arises after psychological overstrain with problems in children in school, and in adults - at work or in the family. Sometimes a nervous tic occurs due to a lack of vitamin B1 or B6, as well as with multiple sclerosis. The activity of nerves that control the movements of the eyelids, suffers from craniocerebral injuries, tumors, which causes blinking eyes in adults.

Dry eye syndrome occurs for several reasons:

1. Disturbance of innervation of tear glands.
2. Blockage of lacrimal ducts.
3. Vitamin A deficiency and xerophthalmia.
4. Reception of oral contraceptives.
5. Dehydration of the body.
6. Overwork on reading, working on a computer( see Gamer's Syndrome).

The tear glands are innervated by the branches of the cranial nerves, secrete a secret that prevents the eyeball from drying out. The tear nerve provides a tear release in small amounts to moisturize the eye. With dysfunction of nervous activity, as well as dryness( xerophthalmia), the frequency of opening and closing the eyes increases. The patient has rezi, the vessels of the white shell burst and blush. This leads to frequent blinking of eyes in children, adults.

Drying with blockage of lacrimal ducts appears as a consequence of metabolic disturbances. The lack of vitamin A also contributes to the drying of sclera, cornea and conjunctiva. Twilight blindness is possible, since retinol acts as a coenzyme in reactions occurring in sensitive retina receptors.

Taking oral contraceptives provokes dry eye syndrome. In this case, bile excretion, absorption of fat-soluble vitamins, including vitamin A., is impaired. Deficiency of retinol naturally leads to xerophthalmia and eyelid twitching.

Overstrain, especially in low light or, conversely, too strong, can cause twitching of the eyelids. The tension of vision causes TV, computer, writing, reading.

Aging eyelid twitching is associated with diseases such as conjunctivitis, iridocyclitis. With this, it is possible to isolate pus, lacrimation, edema of the membranes.

Treatment of

It is necessary to find out what causes the tremor of the eyelids - a nervous disorder, foreign body ingestion or the drying out of the membranes of the eye. In the ticks of neurotic origin, psychotherapy, including family therapy, is used. Establish a normal mode of work( study) and rest, do not allow psychological, mental overload. Recommend a full eight-hour sleep. It is also useful massage before falling asleep, aromatherapy.

Use drugs that calm the nervous system: Pantogam, Phenibut, Pikamilon, vitamins B1 and B6, magnesium, Glycine in vitamin-mineral supplements. You can help tincture of peony, motherwort, valerian. Apply antidepressants, anticonvulsants if necessary.

With dry eye syndrome, drops are used: Artificial tear, Vizin. If SSH is accompanied by a violation of twilight vision, it is recommended to take vitamin A( Aevit capsules or as part of other vitamin-mineral complexes).The use of a sufficient amount of water contributes to the formation, the release of tear fluid, as well as the prevention of dryness and cuts.

If blinking is caused by dryness after blockage of the gland ducts, cleaning them with a tear duct cleanser will be required. Allergic and inflammatory diseases of the conjunctiva, sclera, cornea, iris are treated with drops containing antibacterial and anti-inflammatory substances: Diclofenac, Vizin-Allegi, Sofradex.

If frequent blinking is caused by a foreign body, try to pull it out with a cotton swab. It is allowed to moisten the eye with drops of Vizin, an artificial tear in order to remove dust particles or small insects. In some cases, the help of an oculist( ophthalmologist) will be required, especially when glass particles, metal chips, sharp chips fall.

The tension of the organs of vision is recommended to be removed by periodic gymnastics for eyeballs, timely rest. A complete sleep is also important for the health of the eyes. With frequent blinking in adults, the treatment is determined and prescribed by an oculist. If this is more like a nervous tic, the patient is referred to a neurologist.
