Abstract
Age-related macular degeneration (AMD) is the third leading cause of blindness worldwide1and the leading cause of legal blindness in the United States, where 8% of people older than 65 years have intermediate AMD and 12% of people older than 80 years have advanced AMD.2With increasing longevity, and with the projected doubling of the population 65 years or older by 2020, advanced AMD is expected to increase in prevalence by 50%.3For this reason, it is important to identify modifiable aspects of lifestyle that can lower the impact of this condition.
