Objective To understand the poor vision of preschool children in Hefei city and to provide a basis for making prescriptive and preventive health care measures for preschool children. Methods A standard logarithmic visual acuity chart was used to examine a total of 8 636 preschool children in 72 kindergartens in Hefei city. Results Among the 636 pre-school children, 1 270 were diagnosed as having poor eyesight and 14.7% were visually impaired. The incidence of poor eyesight was 21.2% in 4-year-old children and 13.3% in 5-year-old children 10.8%. There were significant differences in the detection rates of poor eyesight in different age groups, and the incidence of poor eyesight decreased with age. The detection rate of poor eyesight in boys was not statistically different from that in girls. Public parks and private Park children with poor vision detection rate differences were statistically significant. Among all visually impaired children, 86.9% were mild, 8.1% moderate, and 5.0% were severe. Conclusions A comprehensive intervention should be taken from pre-school children so as to reduce the incidence of poor eyesight in preschool children.
