The Relationship Between Subtle Visual Defects and Reading Difficulties

Historical Significance: Trevor Sandy was an optometrist in private practice, who was particularly interested in the relationship between defects of binocular vision and reading difficulties. He was of the view that even minor binocular vision defects could have significant impacts on reading ability and were the causes of severe headaches. Sandy developed idiosyncratic theories and modes of treatments that were not generally accepted by other optometrists or experts in the field. This document was prepared for the National Health and Medical Research Council in an effort to explain his theories and treatments. It contains letters to and from Sandy in regard to his treatements of dyslexic children and reprints of two journal articles
