Diet And Eye Health

diet and eye health

Diet and eye health refers to how the foods and nutrients you consume can affect the function and long-term condition of your eyes. Certain vitamins, minerals, and fats support different parts of the eye: for example, vitamin A is important for the surface of the eye and night vision, antioxidants like vitamins C and E protect tissues from damage, and nutrients such as lutein and zeaxanthin concentrate in the retina and help filter harmful light. Omega-3 fats from oily fish or plant sources help maintain tear quality and may reduce dry eye symptoms. Eating a variety of colorful fruits and vegetables, leafy greens, whole grains, lean proteins, and healthy fats gives your eyes the nutrients they need to work well. A healthy diet also supports overall health — controlling blood sugar and blood pressure through diet helps prevent diabetes-related eye disease and other circulation-related eye problems. Foods high in processed salt and unhealthy fats can indirectly harm eye health by promoting conditions like high blood pressure and poor blood vessel health. For many people, focusing on whole foods rather than supplements is the best first step, though supplements may be recommended in specific cases by an eye care professional. Simple habits like adding spinach, carrots, nuts, and oily fish to meals, staying hydrated, and avoiding excessive processed foods can help protect vision over time. Regular eye exams combined with a healthy diet give you the best chance to maintain good vision as you age.
