Dry eye, also known as corneoconjunctival dryness, is a general term for a variety of conditions characterized by abnormal tear quality and quantity or kinetics caused by various causes, resulting in decreased tear film stability, accompanied by ocular discomfort and causing ocular surface lesions.
A. Common symptoms of dry eye
1, eye fatigue easily after using the eyes for a period of time.
2, itching of the eyes.
3, eye dryness and foreign body sensation.
4, photophobia, blurred vision, in the morning when you wake up eyes can not open, the upper and lower eyelids have the feeling of being stuck together.
5, other symptoms are burning sensation, itching, redness and pain, sticky filamentous discharge, etc.
Second, the common causes of dry eye disease can be caused in life
1, prolonged use of computers, too focused on leading to a reduction in the number of transient eyes per minute, long periods of time without rest.
2, watching television for a long time, especially in the case of watching television without lights on.
3, prolonged driving a car, especially hot air conditioners blowing directly on the face.
4, a long time reading books, without allowing the tired eyes to rest in time.
5, playing video games for a long time.
6, sleep directly after crying, especially after giving birth.
7.Doing other things with a low number of blinks for a long time.
8. having an environment that is so dirty that garbage blocks the exit of the tear and lid glands
9. people with oily skin are prone to blockage of the lid gland outlets.
10. the older you get, the more likely you are to get dry eyes, because the ability to secrete tears decreases with age
11, the human eye in general blinks about 10 times per minute, when using a computer is generally about 5 times, when driving may be less to about 3 times, blink more times to help reduce the chances of dry eye disease.
Third, the treatment of dry eye disease
First line: symptomatic – artificial tears
Second line: compensation of specific components – tear components, growth factors, nutritional factors.
Third line: correct the disease, restore balance – hormones, immunomodulators, tear suppositories, glandular transplantation.
General patients with mild to moderate dry eyes: use artificial tears 4-6 times a day, the number of drops can be increased or decreased appropriately according to the severity of the patient’s symptoms; patients with severe dry eyes: eye gel preparations can be used, eye ointment can be used when there is an exposed corneal ulcer; patients who need to use artificial tears continuously for a long time or patients with severe damage to the corneal epithelium: preservative-free formulations should be used to avoid the toxic effects of preservatives aggravate the damage to the ocular surface and tear film.
Fourth, the prevention of dry eye
1.Use of eyes in a suitable light environment.
2.Give your eyes a 10-minute break every hour or so after prolonged eye use.
3.Intentionally blink more when using eyes under stress (using computer, driving, playing games).
4, with “eyelid massage” instead of static “eyes closed” rest method.
5, eye fatigue immediately with the “eyelid massage” to give the eyes a “big” rest.
