A cataract is one of the common diseases that cause blindness in the world. As one of the risk factors for cataracts, smoking is associated with an increase in cataract prevalence. This study aimed to determine the relationship between smoking with cataracts.  This study was analytical survey research using cross-sectional methods. The population of this study was taken from 265 cataract patients at the Eye Polyclinic, Pirngadi Hospital Medan, North Sumatra, from the period of 01 January to 31 December 2017. Among them, 73 respondents were recruited in this non-probability sampling. A Chi-square test was used to determine the relationship. There were 41 respondents out of 73 who smoked >20 cigarettes had cataract (OR: 6.788, p = 0,00). Smoking more than 20 cigarettes had six times more likely to get cataracts than those non-smokers.
