The eye is a sensitive organ that requires many essential nutrients.<br />Many eye diseases are linked to poor nutrition; therefore, good nutrition plays a vital role in preventing chronic eye diseases.<br /><br />How does nutrition affect vision?<br />- Food provides the eye with energy and essential nutrients.<br />- Nutrient deficiency leads to impaired eye functions.<br />- Oxidative stress affects the lens and retina.<br /><br />Key nutrients for eye health:<br />- Vitamin A: Essential for night vision, maintains the cornea and conjunctiva. Its deficiency causes night blindness and dry eyes.<br />- Vitamin C and Vitamin E: Antioxidants that support retinal health.<br />- Zinc and Omega-3: Help maintain retinal function and reduce the risk of Age-related Macular Degeneration (AMD).<br />- Lutein and Zeaxanthin: Concentrated in the macula, reduce the risk of AMD.<br /><br />Poor nutrition and eye diseases:<br />- Vitamin A deficiency → Night blindness.<br />- Antioxidant deficiency → Cataract (lens opacity).<br />- Omega-3 deficiency → Dry eye and increased risk of AMD.<br />- Chronic malnutrition → Overall weak eye health.<br /><br />Conclusion:<br />A healthy and balanced diet is a powerful tool to maintain eye health and protect against chronic vision disorders.
