Tie too tight will compress the carotid artery and nerves, resulting in lack of blood and oxygen to the brain. Many seemingly very small things in life are closely related to health, such as wearing a tie. As we all know, in modern society, wearing a suit and tie can show elegance, generosity and competence, which is the standard attire for a man in formal occasions. However, who would have thought that the looseness or tightness of the tie is actually related to the health of the eyes? New research shows that if a tie is tied too tightly, it can cause glaucoma. Blurred vision only because the tie is tight Most white-collar workers need to wear a tie during working hours. For people who often work at the desk, tie too tightly will appear in the eyes have some swelling, see things a little blurred, look up to see the symptoms of the symptoms in the distance will disappear. This may have something to do with the tie being tied too tightly in daily life. In the absence of cerebrovascular disease, when the tie is tied too tightly, it will compress the carotid arteries and nerves, obstructing the normal blood flow in the human body, resulting in ischemia and hypoxia of the brain, causing restriction of the normal blood supply, and involving the optic nerve and the arterio-ocular nerve, which will result in symptoms such as swelling of the eyes and blurring of the vision. Especially some office workers engaged in clerical work, due to more low head work, the tie will be relatively tighter, but when you raise your head when the swelling of the eyes to alleviate the symptoms, so just slightly loosen some of the tie, the symptoms will naturally disappear. Some foreign medical statistics show that most of the men who wear ties, because the tie is too tight, causing symptoms of eyestrain. If these symptoms occur for a long time, not only the eyes will be harmed, the brain will also be due to insufficient blood supply to the brain and adverse symptoms. Tight ties can cause open-angle glaucoma. Studies have shown that tight ties can cause glaucoma. Glaucoma is a common disease in ophthalmology, in blinding eye disease, it is also “top of the list”, and glaucoma once caused by blindness is irreversible, so prevention is more important. Ophthalmology according to the different pathogenesis and clinical manifestations of glaucoma is divided into several categories, such as congenital glaucoma, secondary glaucoma, closed-angle glaucoma and open-angle glaucoma, etc., and tie closely related to the open-angle glaucoma. The cause of this type of glaucoma is not yet fully understood, and may be related to heredity. The clinical onset of this type of glaucoma is very insidious, and except for a very small number of patients who have foggy vision or swelling of the eyes, the majority of patients will not be found until they have very poor eyesight or a very small range of things to look at. Moreover, this kind of glaucoma is binocular, so the harm is very great. Why does tying a tie cause open-angle glaucoma? The main reason is that the tie is tied too tightly, which presses the blood vessels in the neck and causes the intraocular pressure to rise, and the rise in intraocular pressure is one of the main factors of glaucoma. If a person often ties his necktie very tightly in his daily life, high intraocular pressure will persistently occur and cause glaucoma, resulting in damage to the optic nerve and retina to the point of blindness. Because the tightness of the tie is closely related to this potential, potentially harmful factor to health, so we remind you to wear a tie friends, when wearing a tie, to give their necks a little “space”, lest the windows of the soul – the eyes are harmed.
