Abstract: ametropia refers to that when the eye does not use adjustment, after the parallel light passes through the refraction of the eye, it can not form a clear image on the retina, but can image in front or behind the retina. It includes hyperopia, myopia and astigmatism., There are many reasons for children’s poor grades. Some come from children’s internal and external reasons, but also from parents’ responsibilities., No matter what the reason is, we can be sure that myopia brings great difficulties to children. As parents, on the one hand, they should take precautions, on the other hand, they should find and treat early., Here is another warning for parents: the specific harm of myopia, 1. Unclear vision, dry eyes and fatigue, which affect the quality of study, life and work., 2. Complication harm: about 15% of myopia patients have one or two or more complications; Experts estimate that one in 170 patients with high myopia will become blind and become a lifelong disability, which will bring a heavy burden to the family and society., 3. It affects the healthy development of children’s body and mind. According to expert research, 72.3% of myopic patients have weak body shape and low body weight bust index. It can be seen that eye diseases such as myopia have posed a direct harm to the all-round development of teenagers’ physical and mental quality, mainly manifested as: it is easy to form psychological tendencies such as cowardice, loneliness and lack of self-confidence, which become character defects., 4. Genetic harm: Patients with high myopia have genetic genes, which are likely to be passed on to the next generation. If both parents are highly myopic, the probability of children suffering from myopia is 93%., 5. Social harm: myopia directly affects the enrollment and employment of patients. Since 2003, the guiding opinions on enrollment and physical examination of ordinary colleges and universities issued by the Ministry of education, the Ministry of health and the China Disabled Persons’ Federation clearly pointed out that those with naked eye vision less than 5.0 cannot apply for flight technology, fire engineering, criminal science and technology and other colleges; Those whose corrected visual acuity is less than 4.8 cannot apply to colleges of marine science and technology, measurement and control, biomedicine, fashion design, aircraft manufacturing, etc; Those with more than 800 degrees can not apply for other majors except normal education, education and social sciences., There are many reasons for the poor performance of
children. Some come from children’s internal and external reasons, but also from parents’ responsibilities.
whatever the reason, we can be sure that myopia has brought great difficulties to children. As parents, on the one hand, they should be prevented, on the other hand, they should be found and treated early.
here once again sounded the alarm to parents: the specific harm of myopia
1. Blurred vision, dry eyes and fatigue, affecting the quality of study, life and work.
2. Complication harm. About 15% of myopia patients have one or two or more complications; Experts estimate that one in 170 patients with high myopia will become blind and become a lifelong disability, which will bring a heavy burden to the family and society.
3. It affects the healthy development of children’s body and mind. According to expert research, 72.3% of myopic patients have weak body shape and low body weight bust index. It can be seen that eye diseases such as myopia have posed a direct harm to the all-round development of teenagers’ physical and mental quality, mainly manifested as: it is easy to form psychological tendencies such as cowardice, loneliness and lack of self-confidence, which become personality defects.
4. Genetic harm: Patients with high myopia have genetic genes, which are likely to be passed on to the next generation. If both parents are highly myopic, the possibility of children suffering from myopia is 93%.
5. Social harm: myopia directly affects the enrollment and employment of patients. Since 2003, the guiding opinions on enrollment and physical examination of ordinary colleges and universities issued by the Ministry of education, the Ministry of health and the China Disabled Persons’ Federation clearly pointed out that those with naked eye vision less than 5.0 cannot apply for flight technology, fire engineering, criminal science and technology and other colleges; Those whose corrected visual acuity is less than 4.8 cannot apply to colleges of marine science and technology, measurement and control, biomedicine, fashion design, aircraft manufacturing, etc; Those with more than 800 degrees can not apply for other majors except normal education, education and social sciences.
causes ametropia:
ametropia refers to that when the eye does not use adjustment, the parallel light cannot form a clear image on the retina after passing through the refraction of the eye, but images in front or behind the retina. It includes hyperopia, myopia and astigmatism. There are many reasons for ametropia caused by
and
, among which genetic factors are very important. Of course, unreasonable eye use can not be ignored. Children are in the period of growth and development and do not pay attention to eye hygiene, such as reading, incorrect writing posture, or poor light, resulting in too close distance between eyes and books, too long reading time, or walking, Reading by car can cause excessive eye fatigue and contribute to ametropia. Pay attention to your diet. Don’t eat too many sweets.
1. Myopia treatment
mild and moderate myopia can be combined with moderate concave lens to correct vision.
high myopia often feels too small, dizzy and difficult to see near objects after wearing glasses. Its degree should be reduced as appropriate, or wear corneal contact lenses, but if the latter is not handled properly, it can cause a series of corneal complications.
myopia laser surgery is often called “excimer laser surgery”. Excimer laser is used to cut the stromal layer under the corneal flap, so as to reduce the corneal curvature of the pupil and achieve the purpose of correcting myopia.
for myopia surgery, many people are afraid of slow postoperative recovery, which will delay their work. Therefore, many myopia patients want to know the speed of myopia surgery recovery. The speed of vision recovery in laser myopia surgery depends on age, refractive adjustment ability of eyes and the degree of myopia before surgery.
generally speaking, young people and those with low myopia before operation recover faster; In addition, Visual acuity (such as reading, fine objects, etc.) at a distance recovers earlier than at a close place. Generally, you can live and work normally after a day or two of rest. However, in the process of postoperative visual acuity recovery, you should pay attention to eye hygiene to avoid eye fatigue and discomfort.
2. Hyperopia treatment
Hyperopia, if the vision is normal and there are no conscious symptoms, it does not need to be treated.
