Children’s poor eyesight is not necessarily myopia, amblyopia is likely to be the culprit

Abstract: myopia is an eye disease caused by the lengthening of the eye axis due to the excessive tension of the eye regulating muscle ciliary muscle or heredity. The corrected vision can reach normal after wearing glasses. Amblyopia is a kind of visual function retardation and disorder, often accompanied by strabismus and high refractive error.

as soon as many parents find that their children have poor eyesight, their first reaction is myopia. As everyone knows, amblyopia is another important reason for vision decline, and amblyopia is more harmful than myopia, but it can be treated after timely intervention. Therefore, amblyopia should attract everyone’s attention.

many people think that poor vision is myopia. In fact, myopia and amblyopia are two concepts.

myopia refers to the problem of the optical structure of the eye, while amblyopia is the functional problem of the cerebral visual cortex. Myopia often occurs in school-age and adolescents, and most of the corrected visual acuity is normal;

amblyopia mainly refers to a functional disease in which the best corrected visual acuity can not reach the visual acuity value consistent with the development period when there are no obvious organic lesions in the eyeball and visual pathway. According to the degree, amblyopia can be divided into mild, moderate and severe: mild amblyopia: visual acuity 0.8 ~ 0.6; Moderate amblyopia: visual acuity 0.5 ~ 0.2; Severe amblyopia: vision less than or equal to 0.1.

amblyopia is more common in preschool, the best corrected visual acuity is less than 0.8, and high myopia can be accompanied by amblyopia at the same time. Amblyopia not only makes children’s vision low, but also affects the development of binocular visual function. The low or lack of stereoscopic function makes life and learning suffer from varying degrees of obstacles.

amblyopia and myopia are not the same disease.

myopia is controllable, and amblyopia can be treated.

myopia is an eye disease caused by the lengthening of the eye axis due to the excessive tension of the eye regulating muscle ciliary muscle or heredity. After wearing glasses, the corrected vision can reach normal, and amblyopia is a kind of visual function development retardation Disorder, often accompanied by strabismus and high refractive error. Wearing glasses can not correct normal eye diseases. The two diseases are essentially different.

amblyopia is much more harmful to children’s visual function than myopia. Because myopia is only the decline of visual acuity when far sighted, without other visual function damage, visual acuity correction is not limited by age; Amblyopia children not only have low vision, can not be corrected, can not have binocular monocular function, no stereopsis, and will not be competent for driving, surveying and mapping and fine work in the future, which will not only affect the future of work. If they are not treated in time, their lifelong vision will be low, but also directly affect the quality of our population.


parents need to pay attention to amblyopia signals. Experts of


point out that amblyopia should be detected and treated as soon as possible. The best age is 3-5 years old. If the eyeball develops and matures after the age of 16, there will be no therapeutic significance.

for children over 6 years old, parents should pay attention to several signals of children’s amblyopia:

children like to put books very close when reading;

like to move forward when watching TV;


often squint at things;


or crooked head at a glance;

turn your face to one side and your eyes to the opposite side;

close one eye and squint in the outdoor sun;


react slowly and act slowly in unfamiliar environment; After


things fall to the ground, stretch out both hands to explore and look for them.

as a parent, if you see these symptoms in your child, don’t simply think that this is “pseudomyopia”. In fact, this may be a sign of amblyopia.

the “amblyopia” of many children is easily regarded as “myopia”, which has lost the best time for treatment. It is not only difficult to treat again after adulthood, but also the effect is very poor. Generally, the treatment effect of 4-6 years old is the best. However, under the pressure of heavy schoolwork at ordinary times, it seems that it is difficult for children to have time for ophthalmic examination. Even children who have been found to have amblyopia can rarely receive systematic treatment, which is a great pity because the cure rate of amblyopia is very high.

in addition, some amblyopia are related to strabismus. From the perspective of symptoms, strabismus is abnormal eye position, and amblyopia is abnormal vision. If parents find that their children have strabismus, ametropia and other symptoms, they should first lead their children to the hospital for a comprehensive examination. Do not mistake amblyopia for myopia and delay the treatment.
