Background: Prevalence of refractory errors has been increasing in community especially among medical students. Various studies in Asian population demonstrate a dramatic rise in prevalence of refractive errors (RE) namely myopia in school and college students.

Objective: This study aims to measure prevalence of refractive errors and its association with various factors which affect their progression among the medical students in Gujarat, India.

Materials and Methods: It is a cross sectional study among medical students studying in their first year. Students were categorised as group A and B respectively depending on absence or presence of refractive errors. Group B students were further investigated regarding their age of detection of refractive errors, progression of refractive errors during school and after entering medical college and family history of refractive errors. Data analysis: Chi-square and z-test is used as appropriate.

Results: Prevalence of refractive errors among medical students in our study is 59.16. Positive family history is strongly associated with presence of refractive error and its progression. Watching TV or computer/mobile phone use and reading in bright light longer time isnít associated with higher prevalence of refractive errors. Recommendations: Habits like computer/TV use, mobile use, reading in very bright or very dark light should be taken care of especially in those with a family history in order to delay the onset and progression of refractive errors.

Key words: Medical students, Refractive errors, Family history, Mobile phone use, Bright light reading
