Carotenoid supplements for better vision in Chinese adults
Part of Brain & nervous system, Eyes & vision clinical trials.
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.
