Unfortunately, eyesight cannot be improved naturally and there is no way to change a refractive error, such as myopia, hyperopia, astigmatism, or presbyopia. These types of visual conditions can be treated with glasses, contact lenses, or refractive surgery.
However, there can be other reasons for diminished eyesight. Macular degeneration causes diminished eyesight but can respond favourably to nutritional changes. In that instance, there are foods that may improve eyesight without glasses.
Fish: Fatty fish contains essential fatty acids, specifically omega-3s. Omega-3s are a part of every cell membrane and therefore play a key role in every cell in the body. In the eyes, omega-3s have been found to be beneficial for dry eye and meibomian gland dysfunction. They also may help with macular degeneration.
Nuts: Nutrition varies depending on the type, but most nuts are powerhouses, containing high levels of protein, essential fatty acids, and fibre. Some nuts, such as almonds and hazelnuts, are particularly rich in the antioxidant vitamin E.
Citrus Fruits: Citrus fruits are rich in vitamin C, another key antioxidant for the eye. Refreshing sources include lemon, lime, grapefruit, and orange.
Leafy Greens: When it comes to foods that help vision, leafy greens receive a high score. They are rich in key vitamins to improve eyesight. Not only do they contain the antioxidant vitamin C, but they are also packed with lutein, a very important carotenoid for the eyes. That spinach won’t just make your muscles stronger; it’ll also strengthen your vision!
Sweet Potatoes: Sweet potatoes are rich in a few key ocular nutrients: vitamin A, vitamin C, and lutein. Substituting white potatoes for the sweet variety not only decreases glycaemic load, but it’s also food for eyesight.
Eggs: Eggs are a great source of vitamins C, E, and lutein. They also contain another carotenoid related to lutein, called zeaxanthin. When it comes to foods that help eyesight, eggs score well. Their combination of nutrients is optimal for fighting macular degeneration.
Beef: Beef is another good food for eyesight improvement. It’s rich in Zinc, which has been shown to slow the progression of macular degeneration.
Legumes: Legumes are a great source of Zinc as well, and offer a great alternative to meat, with their high protein content. When it comes to foods that improve vision, lentils are some of the healthiest, with no saturated fat and high fibre content.
