Many people have the habit of rubbing their eyes. Aunt Li said: how to do itchy eyes? Rubbing eyes comfortable. Zhang said: there are mosquitoes flying in front of you, rub your eyes to rub it off. Xiao Zhao said: sometimes there is fog in front of the eyes, rubbing eyes to see more clearly. Xiao Qian said: eyes flying into a thing, rubbing eyes to rub it out. Xiao He said: “My eyes are rubbed, crusted and caked, so I rub my eyes and pick them with my hands to remove them. The first thing you need to do is to get a good idea of what you’re looking for. Hou Dada’s eyes itch and rub after her glaucoma surgery, so she can’t help but rub her eyes. Is it really comfortable and clear to see after eye rubbing? Li Da Ma’s eyes turned red, itchy and astringent after rubbing because of itchy eyes, to the hospital, the doctor diagnosed as “conjunctivitis”. Xiao Zhang because of flying mosquitoes after rubbing the eyes become more flying mosquitoes, circles, cobwebs, to the hospital, the doctor diagnosed as “vitreous detachment”. Xiao Qian’s eye rubbed after flying into something, the eye became red, eye grinding pain increased, tearing, to the hospital, the doctor diagnosed as “corneal foreign body, conjunctivitis”. Xiao He rubbed his eyes because of eye grinding, out of the eye, resulting in increased eye redness and pain, the other eye also became red, to the hospital, the doctor diagnosed as “acute conjunctivitis”, commonly known as “red eye”. The first time the doctor diagnosed the loss of the anterior chamber after glaucoma surgery, the second surgery was done. Why are there so many problems after eye rubbing? The surface of the human eye is covered with a layer of epithelium, which is very fragile, and it is easy to damage this layer by rubbing the eye. Our hands often carry a lot of bacteria and viruses, and eye rubbing can also contaminate this layer of epithelium. Bacteria or viruses soon take advantage of the situation and multiply, increasing the damage to the epithelium and resulting in conjunctivitis such as eye redness, eye grinding, and increased eye discharge. When the eye enters a foreign body, rubbing the eye makes the foreign body on the surface of the eye embedded deeper and more firmly. Patients with high myopia, people with a history of eye trauma, and as people age, the vitreous humor of the human eye can become degenerated and liquefied, and some people have degenerative areas in the fundus of the eye, i.e., around the retina. Eye rubbing can deform the eye, accounting for four-fifths of the volume of the eye, 99% of the water content of the colorless transparent colloid, that is, the vitreous cushion pressure, deformation, which pulls the retina, or with the tightly attached retina separation, causing posterior vitreous detachment, before the eyes appear flying mosquitoes, meshwork, threads, rings, and floating with the rotation of the eye. The posterior vitreous cortex sharply pulls on the retina, the retinal fissure, if not treated in time, there will be retinal detachment, resulting in lifelong vision loss or even blindness, eye atrophy. The harm of eye rubbing is really not small, if eye itching, blurred vision, flying mosquitoes in front of the eye, eye discharge and other eye discomfort, you can no longer rub your eyes, promptly to the hospital for examination, under the guidance of a doctor for treatment.
