This study links very low vitamin D to a higher risk of mid-stage macular degeneration.
Older adults with very low vitamin D were more than twice as likely to develop mid-stage macular degeneration, a leading cause of vision loss. Researchers followed 429 people over 65 for up to 18 years, tracking blood levels and detailed eye scans. Deficient people also showed slow thickening of a retinal layer tied to the disease, which matters for anyone tracking their vitamin D. No link showed up for advanced AMD, and the study shows only an association, not proof that supplements protect the eyes.
