Summary
This study is testing a smartphone app called eyeFusion that measures how fast your eye can detect flickering lights. The goal is to see if the app can help doctors quickly find blind spots (scotomas) in people with eye disorders. About 500 people, including healthy volunteers and patients with known blind spots, will use the app during their clinic visit.
