Can daily eye vitamins sharpen your vision?

This study aims to see if taking a daily supplement containing specific eye nutrients (lutein, meso-zeaxanthin, and zeaxanthin) for one year can improve contrast sensitivity—how well people see details in low-contrast situations—in healthy Chinese adults. Researchers will compare 220 participants taking either the real supplement or a placebo pill to determine if these nutrients benefit vision in people without existing retinal disease. The goal is to understand if these supplements might help protect against future vision problems like age-related macular degeneration.
