Due to the characteristics of children’s age and the existence of various eye diseases that require treatment, the principles of children’s prescription and adult prescription are completely different. In order to standardize the prescription of children’s glasses in our hospital, so that we can have a unified prescription rule to follow, we synthesize the rules of children’s prescription in other hospitals in China and develop the following principles for your reference: I. Children’s pupil dilatation principles: 1. (2) Children with combined internal strabismus should have their pupils dilated with atropine for five days (to remove the adjustment factor). (3) Children with amblyopia who are able to wear glasses regularly and have the doctor decide whether they can use Midori pupil dilatation before changing glasses (adjustment relaxation). 2. Children over 8 years old: (1) Children complaining of poor vision at the first consultation, Midori or tropicamide pupil dilatation. (2) For children whose vision cannot be corrected after pupil dilatation, they should be referred to the amblyopia and strabismus clinic for medical consultation. (3) Children with combined amblyopia should have their pupils dilated with atropine. (4) After the optometry, if it is simple myopia, the optometry office can directly retest and prescribe glasses. (5) The optometry office can consult a doctor for some special prescriptions (high myopia, large astigmatism, children with progressive myopia). (6) Children who need to consult a doctor are directly added to the professional number by the optometry office (unlimited). (1) Myopia is the lowest correction of the best vision, vision correction to 1, 0 can be (2) Farsighted minus the adjustment prescription, by the optometrist trial and according to vision and symptoms prescription (farsighted minus 1D adjustment) (3) For children who do not cooperate with the examination of myopia regular prescription, farsighted minus 1D adjustment prescription. (1) Children under 6 years old, with adequate correction of hyperopia and astigmatism (low age children have strong visual adaptation ability). (2) Children between 6 and 9 years old, high hyperopia should be reduced, astigmatism should be corrected in sufficient amount, and the second prescription should be adequate for hyperopia. (3) Children over 9 years old with high hyperopia and high astigmatism should be given 2/3 of the first prescription and the second prescription should be given in full (older children have poor adaptive ability) (4) Children with refractive error and younger children can be given an extraordinary amount of glasses (both eyes can exceed 300 degrees). Older children should be given glasses according to medical advice. If amblyopia combined with strabismus needs to be treated, glasses will be prescribed according to the principles of amblyopia prescription without considering the strabismus, and glasses will be prescribed according to the principles of strabismus and surgery after the amblyopia is cured. (1) Exotropia, exotropia A. Combined hyperopia, low correction with glasses (hyperopia is large, can aggravate exotropia) B. Combined myopia, adequate correction, (myopia can control exotropia) (2) Endotropia, endotropia A. Combined hyperopia, adequate correction (hyperopia can control endotropia) B. Combined myopia, appropriate low correction (best vision, minimum) C. Adjustment of internal strabismus, full correction of hyperopia with lenses, change of lenses should be based on the results of the same vision machine to properly reduce the degree of hyperopia, should ensure that the degree of strabismus does not increase the premise of reducing the degree of hyperopia.
