Since children are young and cannot express their feelings correctly, and some eye diseases have no special symptoms, it is more important for parents to observe them carefully and preferably bring their children for regular check-ups to prevent problems before they occur. If a child looks at something with a squinting eye, close together, afraid of light, or tilts his head or face, it is necessary for parents to take their children to the doctor for early detection of amblyopia, strabismus, refractive error and other eye diseases. If there is a family history of eye disease, the child should be examined by an ophthalmologist before the age of 1 week. For children aged 3-6, it is necessary to go to the ophthalmology department of the hospital for a comprehensive examination regardless of whether the child’s vision is good or bad, and if possible, the vision should be examined regularly, once every 3-6 months. At the age of 8-16 years old is the peak period for the onset of myopia in children and adolescents. Therefore, parents should urge their children to develop good eye habits: don’t look at things for a long time at close range, don’t read under too much light or too dark or under sports conditions, and insist on eye exercises. The earlier myopia occurs, the worse the prognosis is, the best way to correct it is to wear glasses, parents should not trust certain instruments and drugs. Some parents believe that “myopia is best not to wear glasses, the more you wear the deeper”, which is not scientific, wear glasses and not wear glasses children’s myopia will rise, especially in the growth period of children, the number of degrees will also have a substantial increase, which is the development of myopia itself is the rule of thumb, and wear glasses have nothing to do. Optometry should go to the regular hospital. Street often claim that “scientific dispensing glasses, immediately available” of the dispensing glasses store, mostly ignored the pupil dilation optometry this step, which is precisely the children and teenagers with glasses before the essential means of detection, because the child’s age, the crystal elasticity is strong, the greater the adjusting force, for the refractive error of the child, if the pupil is not dilated optometry, will be hidden in part, thus affecting the accuracy of the optometry. adjustment, thus affecting the accuracy of optometry.
