“A study funded by the National Eye Institute (NEI), part of the National Institutes of Health, has shown that uncorrected farsightedness (hyperopia) in preschool children is associated with significantly worse performance on a test of early literacy.
The results of the Vision in Preschoolers-Hyperopia in Preschoolers (VIP-HIP) study, which compared 4- and 5-year-old children with uncorrected hyperopia to children with normal vision, found that children with moderate hyperopia (3 to 6 diopters) did significantly worse on the Test of Preschool Early Literacy (TOPEL) than their normal-vision peers. A diopter is the lens power needed to correct vision to normal. The higher the diopter, the worse the hyperopia.”
