Determining Effective Factors on Uncorrected Refractive Errors of High School Students in Zahedan using Statistical Logit Model

Uncorrected refractive errors are some of common diseases worldwide and in particular Iran. Although heredity is one of the most important factors of this sickness, this factor cannot be alone depended on because many various factors are involved in. The most important types of uncorrected refractive errors are Myopia, Hyperopia, and Astigmatism.
