The total astigmatism is measured by an automatic refractor. The astigmatism is corrected by a cylindric lens. For children cycloplegia is required. For children below school age an astigmatism is corrected only if it exceeds 2d. Children older than 6 years will benefit from correction of astigmatism if this is more than 1d. Prescription will be progressive to be supported.
总散光由自动验光仪测量。散光通过柱面透镜矫正。对于儿童，需要进行睫状肌麻痹。对于学龄前儿童，仅当散光超过2屈光度时才进行矫正。6岁以上儿童，如果散光超过1屈光度，矫正将有益。处方将逐渐调整以提供支持。
