Myopia occurs when distant objects passing through the eye's optical system fail to form a clear image on the retina and instead focus in front of it
The most typical symptom of myopia is to see things blurred in the distance, see close to the basic normal.As myopia degree increases, or pathological myopia patient, may amalgamate a few fundus damage, accompany other visual symptoms.
(1) Mild myopia: < -3.00D, 300 degrees or less;
(2) Myopia: -3.00 ~ -6.00D, 300~600 degrees;
(3) High myopia: >-6.00D, above 600 degrees.
Myopia does not happen "all of a sudden" overnight.The reason why parents are "late aware" of their children's myopia is mainly because most parents do not regularly take their children to hospitals or professional optical centers for visual examination, so that they can not detect their children's vision problems early.Therefore, the child's eyes are not just check eyesight, glasses so simple, we need to do is to prevent, early detection of myopia trend.
"Prevention" is far more important than "cure" is our philosophy.What how can ability prevent and control myopia happen and develop?Experts appeal: the establishment of children's refractive development files is the basic steps to prevent myopia!
Through the refractive file, timely attention to the development of the child's eyes, only in the case of detection can let his vision or degree as much as possible control increase, when the child grows up, vision can also ensure a relatively healthy degree.High myopia is the top priority of our prevention and control. If there are people with high myopia at home or cases of more than 600 degrees, 800 degrees or more, we need to be vigilant, do a good job of healthy development files for children earlier, and pay more attention to the port forward of myopia prevention and control.
Can not see clearly may be visual fatigue, may also be hyperopia, and may be caused by eye disease, and can not simply match the mirror, must be serious and scientific detection, and then make a decision, do not hurry to match the mirror, more can not be perfunctory or delay the improper thing.Eyes must be careful!
