Humans observe things in the outside world mainly through their eyes, but human eyes are easily affected by radiation and light, which can cause myopia. Myopia refers to the weakened ability of the eye to form images of external objects, and there are different degrees of myopia depending on the severity of the myopia. However, the readings on your eye chart for measuring vision are different from other degrees. If the myopia on the eye chart is 100 degrees, what is it? 4/5 Step-by-step reading According to the international standard vision chart, if myopia is 100 degrees, the visual acuity is generally 0.8 or 4.9, which is considered mild myopia. However, patients need to be aware that they should not think that they are only 100 degrees myopic and there is no need to worry too much. The optometry director said that if 100-degree myopia is not taken seriously and corrected early, it can easily develop into moderate to high myopia, causing the following complications: 2/5 Eye fatigue Due to unclear vision, the eyes increase their accommodation, and the eye muscles are in a state of excessive tension for a long time, which can easily cause eye fatigue. Symptoms such as eye swelling, eye pain, orbital pain, dizziness, and nausea may occur. 3/5 Macular hemorrhage and degeneration Degenerative myopia is caused by lesions in the fundus, which can cause macular hemorrhage, atrophy and degeneration of the retina and choroid, and seriously affect vision. 4/5 Causes strabismus After myopia occurs, the eye uses less accommodation and more convergence when looking at close objects, which causes an imbalance between accommodation and convergence. The medial rectus muscle is in a state of excessive tension for a long time. Over time, this causes insufficient function of the medial rectus muscle and a corresponding weakening of the convergence function of both eyes, which can easily lead to exotropia or exotropia. 5/5 Retinal detachment Due to the elongation of the eye axis and the liquefaction and degeneration of the vitreous body, the fibrous cords in the vitreous body can adhere to the retina and pull on the retina. When the eyeball is impacted or traumatized, it can cause retinal rupture and retinal detachment. Retinal detachment is the most serious complication of high myopia, and vision is extremely reduced. If not treated in time, it can lead to blindness. |
