Health literacy is defined as “the degree to which individuals have the capacity to obtain, process, and understand basic health information needed to make appropriate health decisions.”1 Health literacy is involved in performing most health care tasks, including, for example, finding the Ophthalmology Department to get an eye exam, communicating effectively with health care providers, and filling out medical and insurance forms to receive health care services. A growing body of evidence shows that, compared to those with adequate health literacy, individuals with low health literacy are more likely to inappropriately or infrequently use health care services,2,3 face difficulty following medical instructions,4–6 have worse physical and mental health,7 and have a shorter life expectancy.8
