Eye care knowledge – what is the difference between amblyopia and myopia!

Abstract: myopia is an eye disease caused by excessive tension of eye regulating muscle ciliary muscle or genetic reasons, which makes the eye axis longer and can’t see clearly, but after wearing glasses, the corrected vision returns to normal; Amblyopia is a kind of visual function retardation and disorder, often accompanied by strabismus, high refractive error, and the visual acuity can not be corrected to normal., 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. Most of the corrected visual acuity can return to normal after wearing glasses, while amblyopia is a kind of visual function retardation and disorder, often accompanied by strabismus and high refractive error. The visual acuity can not be corrected to normal after wearing glasses., What is the difference between amblyopia and myopia?, Myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light is bent through the refractive system of the eye without adjustment. So myopia can’t see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent to the eye, the focus will move backward. When the target moves closer to a point in front of you. The closer this point is to the eye, the deeper the degree of myopia., Symptoms of myopia: it is a refractive state in which the focus falls in front of the retina after the parallel light is bent through the refractive system of the eye without adjustment. So myopia can’t see the distant target., Amblyopia is a problem that the fundus cells of the eye do not develop well without effective light and clear image stimulation. Therefore, even if people with amblyopia wear glasses, their eyesight can not reach normal., Symptoms of amblyopia: 1. Amblyopia only occurs in monocular patients.,

myopia is an eye disease caused by the lengthening of the eye axis caused by excessive tension of the eye regulating muscle ciliary muscle or heredity. The corrected visual acuity can return to normal after wearing glasses. Amblyopia is a kind of visual function retardation and disorder, often accompanied by strabismus and high refractive error. The visual acuity can not be corrected to normal after wearing glasses.

what is the difference between amblyopia and myopia?

myopia refers to a refractive state in which the focus falls in front of the retina after the parallel light passes through the refractive system of the eye without adjustment. So myopia can’t see the distant target. If the target is gradually moved closer to the eye and the light emitted is scattered to a certain extent to the eye, the focus will move backward. When the target moves closer to a point in front of you. The closer this point is to the eye, the deeper the degree of myopia.

symptoms of myopia:

is a refractive state in which the focus falls in front of the retina after the parallel light passes through the refractive system of the eye without adjustment. So myopia can’t see the distant target.

and

amblyopia is a kind of problem that eye fundus cells do not develop well without effective light and clear image stimulation. Therefore, even if people with amblyopia wear glasses, their eyesight can not reach normal.

amblyopia symptoms:

1. Amblyopia only occurs in monocular patients.

2. Amblyopia only occurs in young children.

3. Abnormal vision and refraction.

4. Reading difficulty or congestion.

the difference between amblyopia and myopia

1. Essential difference:

myopia is an eye disease in which the eye axis becomes longer and the vision is not clear due to excessive tension of ciliary muscle of eye regulating muscle or genetic reasons, but the vision is corrected and restored to normal after wearing glasses; Amblyopia is a kind of visual function retardation and disorder, which is often accompanied by strabismus, high refractive error, and the visual acuity can not be corrected to normal.

2. Harm:

myopia is only a decline in vision without other visual function damage. Vision can be corrected and is not limited by age.

amblyopia patients not only have decreased 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.

and

how to prevent the deepening of myopia?

some young people with myopia have normal vision correction after glasses, but after a year and a half, their vision is blurred again, so they need to re optometry and glasses. In this regard, some parents mistakenly believe that myopia will wear glasses deeper and deeper, and the shallower the degree of glasses, the better. In fact, there are many reasons for the deepening of myopia after wearing glasses. Only by analyzing their own eyes and myopia can we find out the cause and make corresponding treatment to prevent the further deepening of myopia. Medical research shows that these are the common reasons for the decline of vision after myopia patients wear glasses.

step / method

1 Do not pay attention to visual hygiene after wearing glasses. When writing or reading, the distance is still quite close, the lighting light is strong and weak, the learning time is too long, and even lie down to read. Watch while walking, watch TV closely, and play video games for a long time. Over time, the ciliary muscle is over regulated, and the degree of myopia is bound to deepen.

  2. The myopia glasses are not suitable. A considerable number of young people with myopia buy glasses from shops or on the street without going to the hospital for mydriatic optometry. In this way, after wearing glasses, due to the temporary enhancement of ciliary muscle regulation, although it will see a little clearer than before, over time, the ciliary muscle will be in a fatigue state due to the improper matching of glasses, resulting in eye acid swelling and vision loss.

  3. Glasses are worn and taken off. Some teenagers regard wearing glasses as a burden and even feel embarrassed for fear of being laughed at. Therefore, they sometimes wear glasses, sometimes don’t wear glasses, or don’t wear glasses in class and after class. As a result, their eyes are often in an unstable state of adjustment. Over time, the degree of myopia has not become shallow, but deepened day by day.

  4. Although people with high myopia often wear glasses, the degree will deepen. This phenomenon is related to family heredity and is clinically called pathological myopia. If such myopia patients do not wear glasses, the degree will deepen faster.

how to prevent children’s amblyopia better?

I. eugenics and good education to prevent amblyopia. Eliminate close relativesMarriage, reduce strabismus, color blindness and congenital cataract caused by autosomal abnormalities; Prevent infectious diseases during pregnancy and use forceps carefully during delivery; Improve the level of health care during pregnancy and reduce the damage to infants’ brain and visual organs.

2. Timely treat eye diseases and prevent amblyopia. Early detection of diseases that can cause amblyopia. Treat strabismus, ametropia, anisometropia, congenital cataract, ptosis and eyelid hemangioma in time to avoid amblyopia. Avoid covering eyes for a long time, which will affect children’s eye development and cause amblyopia.

III. supplement nutrition, do more outdoor activities, promote eye development and prevent amblyopia. Before the age of 5 is the period of children’s visual development. Calcium, zinc, vitamin B2, vitamin A, vitamin C and other nutritional elements needed for visual health should be supplemented. At the same time, more outdoor activities can make children’s eyes mature under the stimulation of natural light and avoid amblyopia.

IV. create a good living atmosphere. Often urge children to pay attention to eye hygiene. The daylighting shall be sufficient and the lighting shall be moderate. Children should read pictures clearly and cultivate good eye habits. All kinds of exercise games, such as blindfold and picking beans, help to find children’s amblyopia early.

v. early detection of children’s abnormal performance and timely detection of amblyopia. Amblyopia children often have other manifestations other than low vision, such as strabismus, squint, or close proximity, and so on. Once the child is found to have strabismus, he should go to the hospital for ophthalmic examination and diagnosis as soon as possible, because about 1 / 2 of strabismus is combined with amblyopia.

VI. regularly check the visual acuity and refractive status to find amblyopia in time. The key to the treatment of amblyopia is early detection and early treatment. After the age of 2, children are generally regularly checked for vision, refractive status, eye position, fundus lesions, etc. every six months. Timely diagnose and treat the problem, so as not to delay the best treatment opportunity.
