Eyesight degeneration is something that naturally happens to everyone during the process of aging. Prescription or over-the-counter treatments can help slow or remedy this process and laser eye surgery has been increasing in popularity recently but there are less expensive ways to prevent or even reverse sight loss.
Refocusing your eyes at regular intervals, wearing sunglasses when in the glare, and refraining from unnecessarily straining your eyes are ways to keep them healthy— but proper nutrition is also key. The different parts of the eye and specifically the retina, the macula, and the lens all require a range of different nutrients to function properly and here are a few of the essential ones.
The three main vitamins necessary for maintaining good eyesight are vitamins A, C, and E. Vitamin A improves vision during the nighttime and in low-light. A concentrated amount of vitamin A can be found in carrots, spinach, broccoli, sweet potatoes, squash, eggs, cheese, and butter. Next, vitamin C, an antioxidant that aids the prevention of cataracts, can be found in most fruits.
Then there is vitamin E, another antioxidant that prevents cell damage and aging in the eyes. Asparagus, avocado, milk, eggs, spinach, nuts, vegetable oils, and whole grain foods are all high in vitamin E.
Another substance, known as lutein, is found in many green vegetables and eggs and is important to preventing macular degeneration. Lutein is one of many types of cartenoids that can be found in vegetables, all of which help preserve eye health. Aside from fighting cataract development, lutein also slows macular degeneration in the eye that happens normally through aging.
For retinal health, omega-3 fatty acids found in fish oil play an important role. One particular omega-3 fatty acid known as DHA has been found to improve color and depth perception. These oils can be integrated into any diet either by eating fish or by taking fish oil supplements.
Even if you are at the point where your eyesight may be getting worse due to age, you don’t have to worry too much or opt for expensive laser eye surgery. Glasses or contacts may become necessary, but to slow down the process of eye detriment— in addition to refocusing your eyes often and avoiding straining the eyes— having a diet that supplies you with the proper vitamins and nutrients can make seeing things clearly a little bit less of a hassle.
