Materials and Methods: In this cross-sectional study, the files of the patients examined in optometry clinic in 2008/2009 were reviewed. Variables included age, sex, rate and type of refractive errors and health of anterior and posterior eye segments. Results: The prevalence rates of myopia, hypermetriopa, astigmatism and emmetropia were 11.83%, 15/38%, 45%, 27/34% respectively. The respective prevalence rates of refractive errors in men and women were: 10/3% and 13/1% for myopia, 16.7%, 15.1% for hypermetropia, 45.6% and 44.5% for astigmatism, and 27.4% and 27.3% for emmetropia. The mean ages of the patients with myopia, hypermetropia and astigmatism were 36.1±19.36, 41.27±22.06 and 32.16±20.98. Respectively Difference of the ratios of the patients with different ages suffering from refractive errors was significant (P SP - 99 EP - 107 AU - Akhgary, Mohsen AU - Tabatabaee, Seyed Mehdi AU - Ghasemi Bromand, Mohammad AU - Aghazadeh Amiri, Mohammad AD - KW - Refractive error KW - Myopia KW - Hypermetropia KW - Astigmatism KW - Age and sex.
