“…27 Orlansky et al compared measures of early academic readiness for preschool children (3 to 5 years olds enrolled in a Head Start) with no astigmatism to preschoolers with astigmatism (≥0.50D in either eye) and found that the presence of astigmatism was associated with lower scores on several measures of academic readiness. 28 Our findings are consistent with results from studies of school based samples: ORF was significantly reduced in astigmatic students when they were not wearing their spectacle correction in comparison to students with little or no astigmatism.…”

“…25,26 In contrast, two studies using school-based samples found significant relations between astigmatism and academic performance and readiness in children. 27,28 In a study of Navajo (Diné) Native American school children, who have a high prevalence of astigmatism, Garber reported that uncorrected astigmatic 5 th and 6 th grade students (≥2.00D) had poorer teacher-assigned reading scores than non-astigmatic students, but found no significant effect of astigmatism on reading scores from standardized tests in 2 nd grade students. 27 Orlansky et al compared measures of early academic readiness for preschool children (3 to 5 years olds enrolled in a Head Start) with no astigmatism to preschoolers with astigmatism (≥0.50D in either eye) and found that the presence of astigmatism was associated with lower scores on several measures of academic readiness.…”

Purpose To compare oral reading fluency (ORF) in students with no/low astigmatism and moderate/high astigmatism and to assess the impact of spectacle correction on ORF in moderate and high astigmats. Methods Subjects were 3rd–8th grade students from a highly astigmatic population. Refractive error was determined through subjectively refined cycloplegic autorefraction. Data from students with ocular abnormalities, anisometropia, symptomatic binocular vision disorders, or refractive error that did not meet study criteria (no/low (cyl < 1.00 both eyes, no significant myopia/hyperopia), moderate (cyl ≥ 1.00 D both eyes, mean ≥ 1.00 D and < 3.00 D), or high astigmatism group (cyl ≥ 1.00 D both eyes, mean ≥ 3.00 D)) were excluded. ORF was tested with a modified version of the DIBELS Next test of ORF. No/low astigmats were tested without spectacles; astigmats were tested with and without spectacles. Mean ORF was compared in no/low astigmats and astigmats (with and without correction). Improvement in ORF with spectacles was compared for moderate and high astigmats. Results The sample included 130 no/low, 67 moderate, and 76 high astigmats. ORF was lower in uncorrected astigmats than in no/low astigmats (p=0.011). ORF did not significantly differ in no/low astigmats and corrected astigmats (p=0.10). ORF significantly improved with spectacle correction in high astigmats (p=0.001, mean improvement 6.55 words per minute (WPM)), but not in moderate astigmats (p=0.193, mean improvement 1.87 WPM). Effects of spectacle wear were observed in students who read smaller text stimuli (older grades). Conclusions ORF is significantly reduced in students with bilateral astigmatism (≥ 1.00D) when uncorrected, but not when best-corrected, compared to their non-astigmatic peers. Improvement in ORF with spectacle correction is seen in high astigmats, but not in moderate astigmats. These data support the recommendation for full-time spectacle wear in astigmatic students, particularly those with high astigmatism.

“…Hyperopic refractive error has been found to be strongly correlated with delayed reading skills and lower academic performance in children . In addition, a recently published study also found a correlation between astigmatism and reading difficulties . Our purpose was to determine eye movement differences between good and poor readers, not to investigate subtle optometric differences.…”

“…Other studies examine whether or not variability in visual tasks predict non-visual abilities or performance. Orlansky et al (2015) found that variability in astigmatism measured in preschool-aged children predicted various forms of reduced academic readiness in various developmental and educational domains, and Wilmer and Buchanan (2009) found that nearpoint phorias after near work predict ADHD symptoms in college students.…”

Individual differences in visual science: What can be learned and what is good experimental practice?

We all pass out our lives in private perceptual worlds. The differences in our sensory and perceptual experiences often go unnoticed until there emerges a variation (such as ‘The Dress’) that is large enough to generate different descriptions in the coarse coinage of our shared language. In this essay, we illustrate how individual differences contribute to a richer understanding of visual perception, but we also indicate some potential pitfalls that face the investigator who ventures into the field.
