Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this project is to test two different types of health messages, one that is developed for a specific group (targeted) and the other that is more personalized to individuals (tailored), to see which is better at changing how often people have their eyes examined. We hypothesize that people who get the tailored messages will be more likely to get a dilated eye exam than people who receive the targeted messages.
