With advancing age, most organs start to lose their functional effectiveness. The eyes are prime examples of this statement as vision loss is common in older adults. While some cases can be treated with medications and surgery, some may lead to complete blindness. Even simple changes in your daily food routine can help prevent major eye-health problems to a significant extent. Here are three food types that have proven eye benefits in the long run.

Foods rich in vitamins A, C, and E
The lack of vitamin A in daily nutrition is known to cause blindness. Vitamin A mainly helps the retina convert incident light into perceived images to complete your vision. Carrots and sweet potatoes can help replenish this vitamin requirement for better eye health. Moreover, fruits that are rich in vitamin C and antioxidants, like blueberries, help repair damaged tissue. Orange, grapefruits, tangerines, and lemons are excellent citrus-rich options that can delay the effect of certain age-related eye diseases. Nuts and seeds rich in vitamin E can further help keep the cells in the eyes healthy and promote better vision.

Foods rich in carotenoid antioxidants
Lutein and zeaxanthin are examples of carotenoid antioxidants that help protect the eyes from harmful UV and blue-light emissions. Foods that are rich in such carotenoids can help reduce the risk of age-related macular degeneration. Several leafy green vegetables can naturally provide this nutrient. Popular picks include Kale, spinach, Swiss chard, parsley, romaine lettuce, collard greens, turnip greens, broccoli, and peas. Avocados, sweet corn, and even eggs can supplement this requirement to promote better eye health.

Foods rich in omega-3 fatty acids
Omega-3s are the essential good fats that the body must process to maintain proper eye function. The retina contains a compound called docosahexaenoic acid (DHA), and any deficiency linked to this DHA can increase the risk of getting macular diseases. Different types of oily fish are rich in natural DHAs to prevent the risk of vision impairment triggered by a deficiency. Salmon, halibut, tuna, sardines, and trout are excellent omega 3 healthy fatty fish that can be used to promote better eye health.

Note that changes in food habits can significantly reduce or even delay the risk of cataracts, diabetic retinopathy, dry eye diseases, glaucoma, and general age-related macular degeneration. Consult your doctor for the right treatment options.
