The prevalence of dry eye among older ages (≥60 years) was 49%, which was higher than younger ages (<60 years). The dry eye had a higher percentage in males than females (44.7% and 39.1%, respectively). Those who had diabetes mellitus for <10 years recorded 36.6% dry eyes, however, those who had diabetes mellitus for ≥10years showed 50.7% dry eyes.
