The Claim
Non-smokers exposed to passive smoking for five or more years have an 87% increased odds of developing end-stage age-related macular degeneration compared to non-smokers with no passive exposure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Non-smokers who breathe in secondhand smoke for five or more years are 87% more likely to develop end-stage age-related macular degeneration than non-smokers with no secondhand smoke exposure.
See the scientific wording
Non-smokers exposed to passive smoking for five or more years have an 87% increased odds of developing end-stage age-related macular degeneration compared to non-smokers with no passive exposure, indicating that secondhand smoke is a significant environmental risk factor for AMD.
Toxic chemicals from secondhand smoke enter the bloodstream and damage the layer of cells behind the retina, causing waste to build up and weaken the barrier that controls blood vessels. This damage triggers abnormal blood vessels to grow into the retina and kills the light-sensing cells, leading to severe vision loss.
What the research says
1 studyEven if you never smoked, living with a smoker for five or more years nearly doubles your risk of developing severe vision loss from AMD, according to this study. The numbers show a clear link between secondhand smoke and this eye disease.
