Still like to play mobile phones in the dark? Be careful to shake out acute glaucoma!

  During the days when you were at home, besides eating and sleeping, did you stay up all night to paint Tik Tok, play the king and follow the drama? The original law of life was disrupted, and the life of night owls who couldn’t afford it during the day and were not sleepy at night was opened. Even if the light is turned off, I can’t bear to put down my mobile phone, and I can brush it under the covers for half an hour when I’m still unfinished. As everyone knows, playing mobile phone in the dark, acute glaucoma is quietly approaching you.

  Playing with your mobile phone without turning on the light can really blind you.

  This is by no means alarmist. Using the eyes in dim light will cause the pupils to dilate for a long time, block the circulation of liquid in the eyes, lead to the increase of intraocular pressure and the acute attack of glaucoma. Persistent high intraocular pressure can also damage the tissues and visual function of various parts of the eyeball, resulting in decreased vision, optic nerve damage and narrowed vision, and may even lead to blindness if not treated in time.

  Of course, playing mobile phones in the dark is only an incentive, and the most important thing is that individuals themselves belong to the "glaucoma quality." "Glaucoma quality" mainly refers to glaucoma patients with high myopia, hyperopia and family history. Once there is an inducement, the intraocular pressure will increase, which will lead to glaucoma. Even if you belong to the "glaucoma quality", don’t be afraid. As long as you control the incentives, the chances of forming glaucoma will be much smaller.

  In addition, playing mobile phones in the dark can easily lead to myopia, dry eye, macular degeneration and other diseases, and "mobile phone family" should take it as a warning. Playing mobile phones in the dark is especially harmful to teenagers’ eyes. Watching the screen at close range in the dark will make them blink less, which will easily lead to visual fatigue. Teenagers’ eyesight is still developing, and in the long run, it will easily aggravate refractive problems such as myopia and astigmatism.

  Four types of people with high risk are more likely to be "stared at" by glaucoma.

  People with grumpy temper Some people are often grumpy. Emotional instability will lead to unstable intraocular pressure, and long-term high intraocular pressure will induce the formation of glaucoma.

  Women over the age of 40 gradually enter menopause, so their emotions are changeable, which are all manifestations of "glaucoma quality". The range of emotional changes is too large, which may easily lead to a sharp increase in intraocular pressure and induce acute glaucoma.

  The eyes of those who overuse their eyes need rest every day just like the brain. However, facing the computer at work and playing mobile phone after work, this habit of using eyes will lead to excessive eye fatigue, which will lead to glaucoma coming to the door.

  Patients with high myopia, high myopia, due to the enlargement of myopic eyeball and the extension of optic papilla, leads to the thinning of the cribriform plate and the sclera near the optic papilla, and the high intraocular pressure compresses the optic nerve, which leads to the gradual atrophy of the optic nerve and the gradual loss of visual field, which leads to blindness.

  How far are you from glaucoma?

  During their stay at home, some people experienced eye pain. For some people, this may be normal, and taking a rest will be fine. But for people with high risk factors of glaucoma, if it is caused by increased intraocular pressure, it may be a sign of glaucoma.

  How to simply judge whether eye pain is caused by increased intraocular pressure? Here is a small method to teach you: "finger measurement" — — With two fingers, it takes only two steps to test whether our intraocular pressure is too high.

  Close your eyes, gently touch the eyeball with your index finger and feel the fluctuation of the eyeball: 1. If it is as soft as your lips, then the intraocular pressure is normal; 2. If it is as hard as the tip of the nose, then the intraocular pressure has increased slightly to moderately; If it feels as hard as the forehead, then the intraocular pressure is already very high. Through this small method of self-test, we can roughly judge whether the intraocular pressure is normal or not. Of course, if you feel obviously uncomfortable, you still need to see a doctor. It should also be reminded that people’s intraocular pressure is not a constant value. Different times of the day are not exactly the same. It is not possible to judge the condition or confirm the diagnosis only by a single intraocular pressure measurement.

  In addition, in addition to eye pain and elevated intraocular pressure, glaucoma has the following symptoms:

  Nausea and vomiting, eye pain and eye swelling When the intraocular pressure rises sharply, it can reflexively cause the excitement of vagus nerve and vomiting nerve center, resulting in severe nausea and vomiting. Trigeminal nerve endings are stimulated, which reflexively causes pain in the distribution area of trigeminal nerve. Patients often feel migraine and eye pain.

  When the visual field narrows and the visual acuity decreases due to the gradual increase of intraocular pressure, the optic nerve is damaged. In the early stage, visual acuity decreases and fog appears at night and disappears the next morning. In the late stage, the visual field is narrowed, which is also the main symptom of glaucoma.

  When the rainbow looks at the light, there are seven colored circles or halos around it, similar to the rainbow in the sky after the rain clears in summer, which is called rainbow in medicine.

  Home "Eye Protection Method" for Glaucoma Patients

  Glaucoma is a lifelong disease. During the period of staying at home, it is easy to have acute glaucoma if you keep a good attitude and stable mood, have a lot of mental stress, think too much, sulk or lose your temper.

  Don’t overuse your eyes, and avoid overusing your eyes to see a bright spot in the dark. When watching a mobile phone, it is best to adjust the contrast of the screen to make the brightness and color as soft as possible. If possible, turn on a low-brightness background light in the room to ease the brightness gap between the screen and the background environment. And keep looking at the mobile phone for no more than 20 minutes, blink consciously and pay attention to "reducing the burden" on your eyes;

  Avoid drinking a lot of water at one time, drink a small amount of water in several times, and try to reduce the amount of drinking water at night to prevent glaucoma;

  For acute glaucoma, sudden eye swelling, eye pain, headache, accompanied by decreased vision, in the case of good self-protection, it is necessary to go to the ophthalmology department in time to reduce intraocular pressure to prevent visual function damage;

  For the primary open-angle glaucoma that has been clearly diagnosed, patients need to take medicine on time, and they can consult online during the epidemic and go to the hospital on an optional basis;

  COVID-19 virus can infect conjunctiva of eyes, which may cause lung infection. Patients with glaucoma, especially those who need to use drugs for a long time, need to pay strict attention to hand hygiene.
