Dual use of cigarettes and e-cigarettes can result in blurred vision

Nguyen AX, Gaiha SM, Chung S, et al. Ocular Symptoms in Adolescents and Young Adults With Electronic Cigarette, Cigarette, and Dual Use. JAMA Ophthalmol. Published online August 31, 2023. doi:10.1001/jamaophthalmol.2023.3852

“This cross-sectional study of 4351 individuals aged 13 to 24 years noted that users of both e-cigarettes and cigarettes have a higher likelihood of experiencing more severe and frequent ocular symptoms than users of a single tobacco product. Cigarette users experienced more ocular symptoms than e-cigarette users, and those who used these products more recently reported more symptoms than others.”

Comment: Use of e-cigarettes can have both immediate vision effects and next-generation effects with adolescent smoking (epigenetic conditions for offspring).
