The relationship between moderate hyperopia and academic achievement: how much plus is enough?
Journal of the American Optometric Association
|November 14, 1997
Abstract
Background:
There is evidence linking uncorrected hyperopia in children with academic learning problems.
Methods:
This study was designed to test that hypothesis and--given supportive data--to then address a second topic: the minimal amount of uncorrected hyperopia that appears to impede elementary school performance.
Results:
The refractive status and achievement test scores of 782 first-through-fifth grade children were compared.
Conclusions:
Statistical analysis indicated significantly lower achievement test scores among hyperopic children whose refractive errors exceeded 1.25 D (ANOVA F = 12.51; df = 4; p = 0.014).
