High myopia, as the name suggests, refers to an abnormal increase in the axial length of the eye, causing light rays to be focused in front of the retina, resulting in an image that cannot be presented clearly. In China, the incidence of high myopia is increasing year by year, which has become a major hidden danger to the vision health of adolescents. This article will deeply analyze the amazing harm behind high myopia, and I hope you will pay attention to it and prevent and intervene in advance.
1. Classification and hazards of high myopia.
1.Axial myopia: an abnormal increase in axial length and is the most common type of high myopia. The harm of axial myopia is mainly reflected in retinal complications, such as retinal detachment, retinal tears, macular degeneration, etc.
2.Refractive myopia: Due to an abnormal curvature of the cornea or lens, light rays are focused in front of the retina. The harm of refractive myopia lies in the lesions of the cornea or lens, such as corneal ectasia, keratoconus, cataracts, etc.
3.Mixed myopia: It has the characteristics of both axial myopia and refractive myopia. The dangers of mixed myopia are more complex and can lead to various complications described above.
2. Hazards of high myopia.
1.Genetic factors: Children with high myopia who both parents are at higher risk of developing the disease.
2.Environmental factors: Prolonged close eye use, poor lighting, and overuse of electronic products can all lead to high myopia.
3.Nutritional factors: Deficiencies in nutrients such as vitamin A, vitamin D, and zinc may lead to axial dysplasia, which can induce or aggravate high myopia.
4.Pathological factors: such as myopic retinopathy, myopic glaucoma, etc.
3. The alarming dangers of high myopia.
1.Vision loss: High myopia leads to blurred vision, affecting daily life and work.
2.Retinal complications: such as retinal detachment, retinal tears, macular degeneration, etc., which may lead to blindness.
3.Refractive surgery risks: Patients with high myopia who undergo refractive surgery, such as laser-corrected vision, may be at higher risk of complications.
4.Ocular lesions: such as corneal ectasia, keratoconus, cataracts, etc., which may lead to vision impairment.
5.Psychological effects: Patients with high myopia may face psychological stress, such as low self-esteem, anxiety, etc.
Prevention and intervention.
1.Regular check-ups: Regular eye examinations are carried out to detect and intervene in the progression of myopia in a timely manner.
2.Scientific Eye: Follow the "20-20-20" rule, take a 20-second break every hour, and look at objects 20 feet (about 6 meters) away.
3.Reasonable diet: Ensure the intake of nutrients such as vitamin A, vitamin D, and zinc, which is conducive to the development of the eye axis.
4.Outdoor activities: Increasing the time spent outdoors is conducive to eye protection.
5.Control the progression of myopia: such as using low-concentration atropine eye drops, wearing orthokeratology lenses, etc.
6.Refractive surgery: For patients who are candidates for surgery, laser correction is effective in improving vision.
In conclusion, the alarming dangers behind high myopia cannot be ignored. I hope that everyone will prevent and intervene in advance to protect their vision health. If in doubt, please consult a medical professional in time.
