Study Description
Brief Summary:
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, symptoms, attention, and reading skills in children.

Condition or disease Intervention/treatment
Hyperopia Farsightedness Device: Glasses for the correction of low to moderate farsightedness Device: Glasses with placebo lens
