Zinc is a vital mineral concentrated in the retina, essential for maintaining eye structure and function, particularly in protecting against age-related macular degeneration (AMD). Supplementing zinc, often combined with antioxidants and copper, can slow the progression of advanced AMD and reduce vision loss risk by about 25% in high-risk individuals. However, zinc balance is important, as both deficiency and excess may harm retinal cells, so consulting a healthcare provider before supplementation is advisable. Including zinc-rich foods like seafood, eggs, and legumes supports preventive eye health naturally.
