Decreased health literacy and accessibility to medical information negatively affect patients and well-informed patients are more likely to experience better health outcomes (1).

Most patients research their disease process using online sources and many reference this material before their initial ophthalmologic consultation. Considering that more than half of Americans read below the equivalent of a sixth-grade level and that the AMA/NIH recommend all patient-intended materials to be written above this level, there is a health literacy disconnect. This limits patients' ability to educate themselves about their medical conditions and participate in informed conversations regarding their healthcare. Patients who are unable to interpret health information accurately have increased rates of hospitalization, develop more medical conditions, and experience a higher rate of mortality. This preventable impediment to informed healthcare care magnifies the urgency for easily readable online resources that are formatted in a manner that is clear to understand and suitable for patients with lower health literacy.</p>","PeriodicalId":51700,"journal":{"name":"Strabismus","volume":" ","pages":"1-8"},"PeriodicalIF":0.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142332088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
