Investigation of the Relationship between Myopia and Intelligence in a Sample of Undergraduate Students

In a sample of undergraduate students, myopia was associated with higher Math and Total SAT score, and males had higher Math and Total SAT scores than females. The association between myopia and higher Math and Total SAT scores was significant only among males, and the gender differences in Math and Total SAT scores were significant only among allergic participants. There were also significant associations between ethnicity and both myopia and SAT scores, but regression analyses revealed that ethnicity, gender, and myopia each made significant independent contributions to Math SAT scores. The findings provide support for Storfer’s theory of myopia and brain growth.
