Thirty-three optometry students, unfamilar with the purpose of the study and with no general binocular dysfunctions, were tested to assess the effect of 7 PD and 5 PD base-in prism on reading comprehension. Subjects wore control and experimental spectacles (no prism and prism, respectively). In a pre-determined time period, the subjects were required to read standardized testing materials and answer comprehensive, multiple-choice questions. Due to a lack of test packet to packet homogeneity, data was rendered inadequate for analysis. However, tendencies were found in which prism does effect reading comprehension. Suggestions regarding improvement in experimental design are discussed.
