This study tests whether taking daily supplements of lutein, zeaxanthin, and fish oil can improve the protective pigment in your eyes. It may help people with low macular pigment and good vision who are not already taking high doses of these nutrients.
This study tests if taking a carotenoid supplement (MacuHealth) can improve or protect retinal health in healthy adults. You might join if you have normal vision and no major eye or health problems.
This study measures a pigment in the eye and also looks at other body tissues in people who have a specific inherited eye condition called adult vitelliform dystrophy. It may help researchers better understand the disease and how it can be confused with early age-related macular degeneration.
This study tests whether taking a supplement containing carotenoids (natural pigments found in foods like carrots and leafy greens) can improve visual function in Chinese adults with good vision. Participants will take the supplement and have their eyes checked over time to see if there is a benefit.
This trial tests a new way to deliver lutein, a nutrient that may help with eye health, directly into the eye using a mild electrical current (called iontophoresis). It is for people with intermediate age-related macular degeneration (AMD), a common cause of vision loss in older adults.
This trial tests whether eating more fruits and vegetables for 12 weeks can improve your skin and how you feel physically. It uses a special light scanner to measure skin health.
