Vitamin A (beta-carotene) is important because its deficiency can lead to dry eye and night-blindness. Its antioxidant effects protect the eye from developing diseases or from macular degeneration. Studies have shown that vitamin A combined with other antioxidants helps slow the progression of neuropathy.
Vitamin E – also an antioxidant – protects eye cells from free radicals.
Vitamin C is important for defending against free radicals and for collagen synthesis; it also slows down the degenerative processes in the eye.
Lutein and zeaxanthin are antioxidants with anti-inflammatory effects. These protect the eye tissue, lenses and the macula, which reduces sensitivity to light and prevents diseases such as cataracts. The body cannot synthesize them on its own, so it needs to be ingested through food (by eating green leafy vegetables) or through supplements.
Omega-3 fatty acids reduce inflammatory processes.
Zinc is one of the most important nutrients because it helps absorb other vitamins and minerals. In combination with other vitamins, it protects the retina and reduces the risk of macular degeneration.
A balanced diet rich in vitamins and minerals, which we find in foods such as carrots, green leafy vegetables; beans, fish and seafood; sweet potatoes, nuts and eggs, is key to maintaining better vision. These vitamins work by strengthening the eye tissue, reducing the sensitivity of the eyes to light, reducing the risk of macular degeneration and cataracts and protecting against the effects of free radicals.
