The Claim
Ever smoking is associated with a 61% increased risk of age-related macular degeneration in prospective cohort studies and a 76% increased risk in case-control studies.
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 have ever smoked have a higher risk of developing age-related macular degeneration compared to those who have never smoked, based on findings from multiple types of studies.
See the scientific wording
Ever smoking is associated with a 61% increased risk of age-related macular degeneration in prospective cohort studies and a 76% increased risk in case-control studies, indicating a consistent association across study designs despite differences in methodology and population selection.
Toxic chemicals in cigarette smoke enter the bloodstream and create harmful molecules that damage cells in the back of the eye. This damage triggers lasting inflammation that weakens the layer supporting the light-sensitive cells and clogs the blood vessels that feed them, leading to vision loss.
What the research says
1 studyStudy: Smoking and the risk of age-related macular degeneration: a meta-analysis.
People who have ever smoked are about 60–75% more likely to develop a serious eye disease called AMD than people who never smoked, and this study confirms that exact range using data from many large studies.
