This study is looking at how well different vision tests work for people with certain eye conditions like Retinitis Pigmentosa, Choroideremia, Stargardt Macular Dystrophy, Stargardt Disease, and Geographic Atrophy from Age-related Macular Degeneration. Researchers want to see how these tests relate to daily activities and how accurately they measure changes in vision over time. You could be eligible if you have one of these conditions and your best-corrected vision is between 20/70 and Hand Motion (HM) in at least one eye. This study does not involve any new treatments or medications; it focuses on improving how we measure vision in people with low vision. The goal is to make sure vision tests are as helpful and accurate as possible.
