Myopia Clinical Trial
Official title:
Potentiating Rural Investment in Children's Eyecare (PRICE)
The aim of the project is to create, study and advocate for a model that can be adopted by the Chinese government to provide spectacles for all children sustainable.
Uncorrected refractive error (URE) is the leading cause of visual impairment among Chinese
children, accounting for 90% or more of poor vision, and Chinese children have among the
highest rates of myopia in the world. Despite the fact that the problem of URE is safely and
inexpensively treated with glasses, only 15-40% of children needing them own and wear
glasses sufficient to provide good vision in rural China.
PRICE (Potentiating Rural Investment in Children's Eyecare) will use a randomized,
controlled design across 4 groups of all 138 schools in Yunnan (one of China's poorest
provinces) and Guangdong (one of the richest) to optimize the model of "free glasses for all
with an optional upgrade." The selection of free spectacles and cost of the "upgrade"
options will be varied between groups in order to find the optimal balance between high
rates of purchase of upgrade glasses on the one hand and good acceptance and wear of free
spectacles among those selecting them on the other.
