How to maintain eyes and prevent dry eye? In recent years, ophthalmic diseases have attracted much attention, and the maintenance of ophthalmology is gradually strengthened. What are the good ways to deal with dry eye? Do your eyes exercise well? Parents often ask us a lot of questions!
Under normal circumstances, the lacrimal glands of the eyes will secrete tears to wet the eyes. But if the eyes are too focused, such as facing the computer for a long time, the eyes will reduce the number of blinks due to excessive focus. Blinking is conducive to the secretion of tears by the lacrimal gland, the uniform distribution of the tear film on the surface of the cornea, and keeping the surface of the eyeball clean and wet.
Blink less, secrete less tears, the eyeball will be dry and uncomfortable due to insufficient moisture. If you stay in an air-conditioned room for a long time, the humidity is low and the air is not circulating, it will accelerate the evaporation of tears, thus inducing dry eye.
For some office workers, because they have to face computer operation every day, the number of blinks is greatly reduced when they are highly focused, and the secretion of tears is also reduced. Coupled with the radiation of screen light, the cornea moistened by tears becomes dry, resulting in eye pain and foreign body feeling.
The general eye drops often contain preservatives and antibiotics, which not only can not change the symptoms of reduced tear secretion, but also cause certain damage to the eyes if used for a long time.
The main manifestations of dry eye are: dry eyes, itching, eye fatigue, foreign body feeling, etc. Experts said that usually these symptoms are not serious and people often don't care.
However, studies have proved that the eyes are dry for a long time, and the damage to the eyeball is unrecoverable. Patients with dry eye disease have dry corneal conjunctival epithelium, and even dry spots and fiber formation, resulting in conjunctivitis and eye infection, and even blindness in serious cases. Attention should be paid to and seek medical treatment in time.
