分析１９８７年全国视力残疾人抽样调查资料，结果显示：我国视力残疾现残率为１０．０８‰；０～１４岁儿童组人群的主要致残因素是先天遗传、屈光不正／弱视、角膜病；６０及６０岁以上老年人群为老年性白内障、沙眼和角膜病；其他人群依次为屈光不正／弱视、白内障和角膜病；青光眼和外伤是导致严重视力残疾的主要原因。作者建议对视力残疾实行三级预防措施，其中关键是一级预防。其重点是开展遗传咨询和孕期保健工作，预防眼部感染和外伤，并积极治疗原发病（如糖尿病）。
Analysis of the 1987 national sample survey of visually impaired persons showed that the prevalence of visual disability in China was 10.08 ‰. The main disability factors of children aged 0-14 years were congenital anomalies, refractive errors / amblyopia, corneal diseases ; 60 and older people over the age of 60 were age-related cataract, trachoma and corneal disease; other groups were refractive error / amblyopia, cataracts and corneal disease; glaucoma and trauma were the main causes of severe vision disabilities. The author recommends three levels of prevention of visual impairment, of which the key is a primary prevention. Its focus is on genetic counseling and prenatal care, prevention of eye infections and trauma, and active treatment of primary disease (such as diabetes).
