The Effect of Eye Fatigue on Reading, Based on Test Scores and the Presence of Deviant Eye Coordination, Either Esophoria, Exophoria or Hyperphoria.
Gillis, George A.
Studied were eye coordination and effects of fatigue on vision in the visual and academic functioning of 1049 students in grades 1 through 10. An earlier study (1966) examined the eye coordination of 1152 students in grades 1 through 12. The common Snellen Test of Visual Acuity failed to indicate 42% of students who were diagnosed by other tests to have eye problems. Tests of eye coordination tendencies found students to be either orthophoric (perfect eye coordination), exophoric (laterally divergent) hyperphoric (vertically divergent), or esophoric (laterally over-convergent). Orthophoric students tended to be the youngest in their classes, to be good readers, and to cost less to educate. Esophoric students were poor readers, the oldest in their classes, and the most expensive to educate. Welfare students with esophoric eye coordination tested lower on IQ and reading than their esophoric non-welfare classmates. It is recommended that each child receive a clinical vision check early in his school life. (DB)
