Everyone wants to have healthy and bright eyes, but many people are troubled by myopia. The number of myopia in China has reached 600 million. The myopia rate among adolescent students is close to 50%. The problem of myopia in adolescents should be paid attention to by the society and parents.
Nearsightedness above 600 degrees is highly myopia. High myopia not only affects vision, but can also cause damage to the fundus and the entire eye. The incidence of fundus disease with high myopia increases significantly as patients age.
Parents should treat their children's myopia correctly, not be overly anxious, and not be indifferent. Once a child develops myopia, early intervention and control are required, including wearing contact lenses, peripheral defocusing glasses, medications**, outdoor activities, etc. At the same time, it is necessary to train children to develop good eye habits, pay attention to eye hygiene, and do not blame electronic products for myopia.
High myopia surgery only changes the refraction of the cornea, and does not change the fundus axial at all. Therefore, after myopia eye surgery, the fundus will still be the fundus of high myopia, and the probability of high myopia fundus disease is still the same.
True myopia is when light rays are focused in front of the retina after passing through the eye's refractive system, resulting in blurred vision of distant targets. Pseudomyopia, on the other hand, is caused by improper use of the eyes. For true myopia, you can only rely on wearing glasses to improve your vision, and you can't recover it. For pseudomyopia, as long as you can get proper rest and **, pay attention to eye hygiene, you can restore normal vision.
Children must dilate their pupils for refraction. In children, the purpose of dilating pupils is to relax the eye muscles and eliminate the accommodative effect to obtain the true refractive power. Pupil dilation can distinguish between true myopia and pseudomyopia.
If the child's myopia is above 100 degrees, he should always wear glasses, and do not wear them from time to time. If the prescription is within 100 degrees, you can wear glasses when your vision is not clear.
