Dataset Information

Population prevalence of myopia, glasses wear and free glasses acceptance among minority versus Han schoolchildren in China.

ABSTRACT:

Aim

To measure myopia, glasses wear and free glasses acceptance among minority and Han children in China.

Methods

Visual acuity testing and questionnaires assessing ethnicity, study time, and parental and teacher factors were administered to a population-based sample of 9-12 year old minority and Han children in Yunnan and Guangdong, and their teachers and parents. Refraction was performed on children with uncorrected visual acuity (VA) < = 6/12 in either eye, and acceptance of free glasses assessed.

Main outcome measures

Baseline myopia (uncorrected visual acuity < = 6/12 in > = 1 eye and spherical equivalent refractive power < = -0.5D in both eyes); baseline glasses wear; free glasses acceptance.
