The popularity of "Rage Wind" has led many netizens to dig into the details of the play. Some careful viewers may find that Gao Qiqiang, who competes with Gao Xiaochen on his bicycle, always puts down the lens on his helmet before leaving. But he is not afraid of death. Is this detail protecting his eyes? In fact, his action provided him with crucial technical support to win, which should start from his root cause - dry eye disease. It is believed that many people have the same question as Chen Shuting when watching TV dramas: What is dry eye disease? Dry eye is actually a very common disease. About one in three Chinese people has dry eye. Under normal circumstances, a film formed by tears is evenly distributed on the surface of the eye, which plays a key role in refraction, lubrication and immunity. Although the tear film is thin, it can also be divided into three layers according to its composition: oil, water and mucus. When the stability of the tear film is reduced and the eye cannot provide enough lubrication, dry eye will occur. The causes may include hormone changes, autoimmune diseases or allergic eye diseases. However, for most people, dry eye can be simply divided into "insufficient secretion type" and "excessive evaporation type" according to its causes. If the eyes do not produce enough tears, "hyposecretion" dry eye may occur; When the oil secreted by the meibomian gland is insufficient, the dry eye disease of "excessive evaporation" often occurs. In addition to often making people feel dry and astringent, dry eye sometimes also makes people feel tingling, burning, itching or foreign body sensation in the eyes, and some people will complain that there is mucus in or around the eyes, or sensitive to light, and even some people will have red eyes, tears, blurred vision or visual fatigue. In order to relieve the symptoms of dry eyes, in addition to the "eye drops" mentioned in the play, we should also pay more attention in life to prevent the wind from blowing directly into the eyes. Although it is not necessary for most people to wear goggles and goggles during cycling, for patients with dry eye disease, preventing the intrusion of stroke on the eyes during cycling can largely alleviate the symptoms of "tears in the wind". So if you also happen to have dry eyes, you might as well choose helmets with glasses such as full helmets and three-quarters helmets when purchasing helmets, so that you can ride safely without tears.
