Chinanews.com, Guangzhou, October 15 (Cai Minjie, Lin Yuzhen) With the advent of the "screen reading" era and poor eye environment and behavior habits, the incidence of dry eye is increasing year by year.
Guangzhou Aier Eye Hospital affiliated to Jinan University launched the "Dry Eye Care Day" and "Dry Eye Public Welfare Inspection" project on the 15th.
According to Mansha, the head of the Department of General Diseases of the hospital, dry eye is a chronic disease, which can cause discomfort, namely irritation, dryness, and pain; in severe cases, it can cause corneal ulcers, even perforation, and eventually blindness. Early detection, early intervention and early treatment are required."
Dry eye is caused by abnormal tear quality or quantity or abnormal dynamics caused by various reasons, leading to the decrease of tear film stability. It is a high-incidence eye disease of modern people.
He Mansha said that the common symptoms of dry eyes are foreign body sensation, dryness, pain and fatigue in the eyes, sometimes sensitive to wind and air conditioning, and sometimes vision fluctuations and blurring.
It is reported that there are four types of people who are prone to dry eye: one is people who stay up late and use their eyes for a long time; the second is people who wear makeup and contact lenses for a long time; the third is the elderly, especially women; the fourth is diabetes, People with high blood pressure and other diseases, as well as people who take some drugs for a long time, including antidepressants and analgesics.
"A normal person blinks 15 to 20 times per minute. However, when we are staring at the screen for work, study, playing games, watching dramas and driving, the number of blinks per minute is only 5 times." He Mansha introduced, blinking and calling. Blinking can evenly distribute the tear film to the eye surface and moisten the eyes when blinking; at the same time, people can also promote the discharge of lipids (commonly known as "oil") secreted by the meibomian glands by blinking.
As an important part of the tear film of the eyes, the role of lipids is to "lock water and moisturize", protect the tears from evaporation, improve the stability of the tear film, and prevent dry eyes.
However, when people stare at the electronic screen, their eyes will enter into a state of "focus" without blinking. If they unconsciously reduce the number of blinks, the lipid secreted by the meibomian glands will decrease; in addition, if people "not completely blink" , That is, every time you blink, the entire cornea cannot be completely covered, and when the quality of the blink is reduced, the lipid excretion is not strong enough, and the secretion of lipids will also be reduced.
Due to the lack of lipid protection, the stability of the tear film is weakened, and the evaporation of tear fluid is intensified, which is prone to dry eyes.
"We advocate that the whole people should perform correct blinking exercises 10 times a day (the steps of blinking are lightly closing the eyes for two seconds, closing the eyes for two seconds, and opening the eyes for two seconds, repeating this cycle), one training for 1 minute, At the same time, consciously increase the blinking frequency." He Mansha said.
"In addition, in order to check whether you have'incomplete blinking', we also recommend that everyone must go to a professional ophthalmology medical institution for examination to fully understand the quality of blinking and prevent dry eye." He Mansha said, dry eye Treatment is not just a matter of using eye drops at will. It is necessary to distinguish the type and degree, and then conduct personalized treatment for each patient's different conditions. (Finish)
