Boys’ myopia is not treated for 2 years. 50 degrees are dragged to 600 degrees

Abstract: due to the limitation of urban living environment, dense housing and heavier academic burden, children are generally lack of outdoor activities. Forming a good habit of daily exercise can not only alleviate eye fatigue, but also activate cells. It is the most ideal eye maintenance method. But don’t ignore the damage of strong light to your eyes, so you’d better wear a protective sun hat and sunglasses for outing. The concept and classification of

myopia

and

myopia refers to that the focus of parallel light after refraction of the eye is located in front of the retina when the eye is adjusted in a static state, and the vision is blurred when looking at distant objects.

myopia below 300 degrees is mild myopia, 300-600 degrees is moderate myopia, and more than 600 degrees is high myopia. Classification and characteristics of

myopia:

(1) pathological myopia has early onset age, high myopia degree, progressive development of myopia, poor vision correction, easy to find complications (retinal detachment, etc.), and obvious genetic factors.

(2) the age of onset of physiological myopia is relatively late, generally medium and low, the diopter develops stably in adulthood, the visual acuity correction can be normal, generally there are no complications, and the genetic factors are not obvious.

(3) accommodative myopia is pseudomyopia. The degree of myopia is low. Pay attention to the use of eyes, and the vision can return to normal.

causes of myopia

genetic factors

according to statistics, if the number of children with myopia with normal vision is taken as the benchmark, the number of myopia patients with myopia of one of their parents is 3.8 times that of their parents. Moreover, the heredity of medium and high myopia is 2.6 times higher than that of high myopia; The genetic tendency of myopia is more obvious when both parents are myopic. Therefore, if parents are myopic, they need to pay special attention to their children’s eye habits, learning environment and diet, so as to delay the age of children suffering from myopia as much as possible.

improper diet

1 Excessive sweets increase the incidence rate of myopia.

  2. Eating too much essence or partial or picky food, causing vision loss;

  3. Eating too little hard food leads to an increase in juvenile myopia.

improper eye use

1 Incorrect reading and writing posture and too close eye distance; Often lie down or read by car;

  2. Poor ambient light, improper height of desks and chairs;

  3. Stare at TV, computer and mobile phone for a long time.

outdoor activities are insufficient.

and

are restricted by the urban living environment, housing is intensive, and the academic burden is increased. Now children generally lack outdoor activities. Forming a good habit of daily exercise can not only alleviate eye fatigue, but also activate cells. It is the most ideal eye maintenance method. But don’t ignore the damage of strong light to your eyes, so you’d better wear a protective sun hat and sunglasses for outing.

myopia prevention for children and adolescents

adequate outdoor activities

research shows that outdoor activities for 2 hours a day can effectively prevent the occurrence of myopia.

reduce close eye use

reduce close work, especially reduce continuous close work, which is an effective method to prevent myopia. Generally speaking, every 40 minutes of continuous close reading, you should rest and overlook for 10 minutes.

establish refractive files

parents are most concerned about how to find children’s “signs of myopia”. The traditional practice is to suspect myopia when children are found to be near, abnormal head position (deflection) and squint when watching TV. However, when the above situation occurs, it is common to find high myopia above -6.00d (600 degrees) for the first time in clinical optometry. Establishing refractive files for children is the best way to prevent myopia. We should establish refractive files for children in regular eye hospitals from the age of 3.

what is a refractive file

is to record the development process of the eyeball, that is, regularly record the corneal curvature, eye axis, ciliary muscle paralysis, intraocular pressure and other indicators, and continuously track the development of children’s eyeball and body. When these indicators are abnormal and develop into myopia, they can send out “early warning” in time to attract parents’ attention and take measures, Avoid or delay the occurrence of myopia.
