Abstract: Objective To investigate the current situation of 0 to 6 years old children's refraction,and provide information for detecting refrangibility. Methods A total of 17 356 children aged from 0 to 6 years old were examined with Suresight hand-held refractometer.The data were ananlysed statistically. Results Compound hypermetropia astigmatism and simple hypermetropia were predominant in the reflection types in 0~6 years old children.Hypermetropia and compound hypermetropia astigmatism decreased with the age increase(P<0.01).Emmetropia,myopia,simple myopia increased with the age increase(P<0.01).The spherical diaopter and the cylinder diopter decreased with the age increase.The reference ranges of all aged groups were gained. Conclusions It is necessary to check the 0~6 years old children's refraction.Much attention should be paid attention to detecting refrangibility and the age factor to prevent overdiagnosis.
