Correction of Farsightedness in Children Study

Hyperopia (farsightedness) has been reported to be associated with reduced visual perceptual
and reading abilities. However, there is controversy regarding whether or not to prescribe
for low to moderate amounts of hyperopia. The Correction of Hyperopia In Children Study
(CHICS) is a placebo-controlled, randomized, masked investigation of the effect of spectacle
correction for moderate amounts of hyperopia on visual function, attention, and reading
skills in children.
