Draw the point
★ Frequently washing the eyes with "eye wash" will reduce the self-cleaning function of the eyes and even affect the immune mechanism of the eyes.
★ The incidence of dry eye in China is as high as 21%-30%, and the incidence is increasing year by year, and the diseased population is developing younger.
★ Daily can choose artificial tears to alleviate the dry eyes caused by mild dry eye disease, artificial tears without preservatives is a better choice, but long-term use needs to follow the advice of a doctor.
When you see something dirty, you have to "wash your eyes." Before the so-called "eye wash" came out, eye washing was just a stem that everyone used to ridicule.
Unexpectedly, in the past two years, under the overwhelming publicity of the anchors with goods, "washing eyes" has become the same as "bathing" and "washing hands", and the cleaning steps that have to be done every day have to be used.
Ms. Zhang, who lives in Beijing's Tongzhou District, bought "eye wash" and cleaned her eyes regularly every day under the influence of the anchor. As a result, it didn't take long for Ms. Zhang's eyes to appear "dry and astringent, and she always felt the wind blowing into her eyes." According to the doctor's judgment, Ms. Zhang was diagnosed with mucin deficiency dry eye.
01
Frequent washing of the eyes is harmful to the eyes
The human eyeball is generally covered with a stable tear film, which is used to keep the eye moist and allow us to see clearly. The tear film is divided into three layers, from the outside to the inside, the lipid layer, the water-like layer and the mucin layer.
The function of the gelatin in the tear film is to fix the aqueous layer of tear fluid to the cornea and the epithelial surface of the conjunctiva, forming a tear film and forming a smooth interface on the surface of the cornea. Mucin is also involved in the defense function of the eye, resisting the adhesion of pathogenic microorganisms.

Ms. Zhang frequently washed her eyes, destroying the mucin in the tear film, causing the eyes to become drier and drier, which eventually led to protein deficiency dry eye.
Under normal circumstances the eyes do not need to be washed at all. The tear fluid produced by the eyes itself has a clean and protective effect on the conjunctival sac, and is the best natural substance for cleaning the eyes.
Frequent artificial eye washing, not only will not achieve the purpose of "net", but will make the self-cleaning function of the eye decline, destroy the normal microenvironment of the eye surface and the immune mechanism of the eye, and cause irreparable damage to the cornea and conjunctiva.

Medical "eye washing" is a treatment that mainly cleans the conjunctival sac for patients with conjunctivitis, acid burns, alkali burns, etc., to remove pathogenic microorganisms. Is it necessary to wash your eyes, it is best to listen to the doctor's advice, and washing your eyes should also go to a regular hospital.
02
With dry eye, artificial tears are chosen to have a doorway
Ms. Zhang suffered from dry eye disease because of excessive cleaning of her eyes. In fact, dry eye is becoming more and more common.
Due to the changes in the living environment, the popularity of electronic products such as mobile phones and computers and environmental pollution are becoming increasingly serious, and the incidence of dry eye disease is increasing year by year and showing a trend of rejuvenation. Surveys show that the incidence of dry eye in China is as high as 21%-30%.
When the eyes are dry and itchy, many people will choose to order artificial tears on their own. However, it is easy to enter the misunderstanding in use, and the wrong use will bring harm.

Mild dry eye can use artificial tears, artificial tears are a substitute for components that mimic human tears, and the ingredients are mainly polyethylene glycol, sodium hyaluronate, methylcellulose, chondroitin sulfate, etc.
Patients with different degrees of dry eye should choose appropriate artificial tear fluid to alleviate the symptoms of dry eye. Patients with mild dry eye should choose low viscosity, while patients with severe symptoms should choose high viscosity artificial tears.
At present, the number of artificial tear preparations that do not contain preservatives in single-dose packaging has gradually increased, which not only reduces the damage of preservatives to the corneal epithelium, but also prevents pollution, which is currently an ideal ophthalmic preparation. Although artificial tears can be purchased without a doctor's prescription, long-term use should also be used with ophthalmology consultation, and the drug should be used rationally under the guidance of a professional ophthalmologist.

To prevent dry eye, you have to start with small things
Dry eye is not just caused by temporary fatigue, it needs to be paid attention to and intervene as soon as possible. Otherwise, it can lead to filamentous keratitis, corneal epithelial keratosis, and in severe cases, it will cause inflammation of the ocular surface, leading to corneal ulceration, and even blindness.
In daily life, the best way to avoid dry eyes is to pay attention to the "moisturizing" of the eyes. The following tips can help you better protect your eyes and avoid dry eye.
