The Claim
Current smokers have a higher risk of age-related macular degeneration than past smokers, with pooled relative risk estimates of 1.76 for current smokers versus 1.61 for ever smokers, indicating that smoking cessation reduces but does not eliminate the risk of age-related macular degeneration.
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.
People who currently smoke have a higher risk of age-related macular degeneration than people who used to smoke but have quit. Quitting smoking lowers the risk but does not remove it entirely.
See the scientific wording
Current smokers have a higher risk of age-related macular degeneration than past smokers, with pooled relative risk estimates of 1.76 for current smokers versus 1.61 for ever smokers, indicating that smoking cessation may partially reduce but not eliminate AMD risk.
Toxins from cigarette smoke build up in the back of the eye, damaging cells that support the light-sensitive layer. This damage causes constant inflammation and oxidative stress, which slowly kills the cells needed for clear vision. Even after quitting, some toxins remain and keep causing damage, so the risk never fully goes away.
What the research says
1 studyStudy: Smoking and the risk of age-related macular degeneration: a meta-analysis.
People who still smoke now are more likely to get a serious eye disease called AMD than people who quit smoking, but even those who quit still have a higher risk than people who never smoked. So quitting helps, but doesn’t make the risk go away completely.
