According to the American Optometric Association, more than 25 million people across the globe are affected by age-related macular degeneration and cataracts, which are the leading cause of blindness in people over the age of 55.
Researchers have proven that food rich in the nutrients lutein and zeaxanthin can reduce the risk of chronic eye diseases. Other studies have shown that a diet rich in vitamins C and E, beta carotene, zinc and omega-3 fatty acids can also prevent age-related eye diseases. Here are five foods that can help improve your eyesight naturally:
As eggs are loaded with protein, they are especially beneficial to the eyes. Two antioxidants, lutein and zeaxanthin, are also present in eggs and have been linked to preventing damage in eyes from UV exposure. Egg yolks have lots of vitamin A, which keeps your eyes healthy. Consuming eggs may also lower the risk of cataracts and other common eye disorders.
Carrots contain both beta-carotene and lutein. These compounds can be found concentrated in our retinas, which protect vision.
Studies have shown that avocados contain more lutein than any other fruit, which is important for improving your eyesight since the lutein has the ability to reduce the risk of macular degeneration and cataracts.
Packed with lutein and zeaxanthin, spinach improves eyesight by reducing your chances of cataracts and other eye diseases. Add spinach to sandwiches and wraps, and use it as a salad starter or make smoothies with it. Cooking the greens helps your body better absorb the lutein.
