Switching to Vapes May Raise Eye Disease Risk, Major Study Finds
A large Korean study of 32,316 matched former smokers followed for about 4.6 years found that those who switched to electronic cigarettes or other smokeless nicotine products had a higher risk of major eye diseases than those who quit nicotine entirely. Specifically, switchers had a 24% higher risk of diabetic retinopathy and a 7% higher risk of refractive/accommodation disorders, with quitters showing 41.1 vs 44 cases per 1,000 person-years. The study observed 6,328 eye-disease events overall. Authors caution that the retrospective, self-reported data cannot prove causation, but the findings suggest substituting nicotine products may not eliminate eye-disease risk.
