Although the prevalence of smoking has decreased in the last decades, it remains frequent in adults aged 20 to 40 years, who typically are parents of young children. A considerable proportion of children are thus exposed to parental smoking, with well-demonstrated associations with their current and future cardiovascular health.1 Smoking also has strong associations with ocular health, with increased risks of age-related macular degeneration, cataract, ischemic and inflammatory eye diseases, and possibly glaucoma.2,3 However, nearly all studies have been conducted in elderly or middle-aged individuals, and they have only investigated the outcomes of active smoking (duration, quantity smoked, and smoking cessation). Little is known of the effects of exposure to smoke during childhood on ocular health.
