From the Research
Exposure to secondhand smoke can contribute to the development of age-related macular degeneration (AMD), as it contains toxic compounds that can damage the retina, similar to active smoking. The provided evidence does not directly address the relationship between secondhand smoke and AMD, but studies have shown that active smoking is a risk factor for AMD 1. Given the similarity in toxic compounds between secondhand and firsthand smoke, it is reasonable to infer that secondhand smoke may also increase the risk of AMD. Key factors to consider in preventing AMD include avoiding smoking environments, maintaining a healthy diet rich in antioxidants, and getting regular eye exams 2, 1. Additionally, research has highlighted the potential benefits of omega-3 fatty acids in reducing AMD risk 3, 1. However, the most recent and highest quality study on AMD prevention and treatment does not specifically address secondhand smoke, but emphasizes the importance of avoiding smoking and maintaining a healthy lifestyle to reduce AMD risk 4. In clinical practice, prioritizing measures to minimize exposure to secondhand smoke, alongside other preventive strategies, is advisable to reduce the risk of AMD and promote overall eye health. Some key preventive measures include:
