Nutrition and Eye Health: Tips from Your Glenview Optometrist
Corner Optical in Glenview knows that good vision isn’t just about regular check-ups—it’s also about what you eat. Patients often ask for eye health tips, and one of the biggest eye health tips we share is to maintain a balanced diet. As a local optometrist in Glenview, we’ve seen firsthand how proper nutrition can improve eye health over the long term. In fact, there’s truth to the old saying about carrots being good for your eyes – carrots are rich in vitamin A, which your eyes need to see in low light and to keep the cornea (front of the eye) moist (Vitamin A Deficiency: Causes, Symptoms, Treatment & Prevention) (Vitamin A Deficiency: Causes, Symptoms, Treatment & Prevention). In this blog, we’ll explain the link between diet and healthy vision, highlight key nutrients (like vitamins A, C, and E; omega-3s; lutein; and zeaxanthin), and give examples of foods that keep your eyes strong.
Why Nutrition Matters for Eye Health
The health of your eyes is closely tied to your overall nutrition. Just as a healthy diet benefits your heart and bones, it also benefits your vision. Certain vitamins and antioxidants help protect the eyes from damage and age-related changes. Researchers have found that eye-friendly nutrients such as lutein, zeaxanthin, vitamin C, and vitamin E are linked to a lower risk of serious eye diseases like age-related macular degeneration (AMD) and cataracts (Diet and Nutrition | AOA). In other words, good nutrition for vision isn’t a myth—it’s a crucial part of maintaining Glenview eye care for patients of all ages. Eating plenty of fruits, vegetables, and omega-3-rich foods can keep your eyes functioning at their best and even help prevent common eye problems down the road.
Essential Nutrients for Healthy Vision
(10 Foods That Are Good for Your Eyes)Leafy greens like kale (pictured below) and spinach are great examples of vision-boosting foods. They contain high levels of lutein and zeaxanthin, antioxidants that concentrate in the retina and help protect your eyes from harmful light. Many studies show that lutein and zeaxanthin can reduce the risk of chronic eye diseases, and people who get the most of these nutrients have a much lower risk of developing new cataracts (Diet and Nutrition | AOA). Of course, lutein and zeaxanthin are just two of several key nutrients for eye health. Here are some of the most important vitamins and nutrients — and how they help your eyes:
Vitamin A: Often known as the “vision vitamin,” vitamin A is critical for low-light vision and maintaining a clear cornea. Getting enough vitamin A can help prevent night blindness and dry eyes. Foods rich in vitamin A (or its precursor, beta-carotene) include carrots, sweet potatoes, butternut squash, and cantaloupe. Even eggs and dairy products provide some vitamin A. If you include these in your diet, you’re giving your eyes the tools they need for sharp vision at night and comfortable, moist eyes during the day (Vitamin A Deficiency: Causes, Symptoms, Treatment & Prevention) (Vitamin A Deficiency: Causes, Symptoms, Treatment & Prevention).
Vitamin C: This antioxidant powerhouse supports the blood vessels in the eye and helps slow down the progression of cataracts and AMD. Vitamin C is also essential for collagen formation, which is important for the cornea and sclera (the white of the eye). You can find vitamin C in citrus fruits like oranges, lemons, and grapefruit, as well as in strawberries, bell peppers, broccoli, and tomatoes. Snacking on an orange or adding bell peppers to your salad is an easy way to get your daily dose of C (Diet and Nutrition | AOA).
.
Vitamin E: Vitamin E protects the cells of the eyes from damage by free radicals (unstable molecules that can break down healthy tissue). In doing so, it may help prevent age-related damage like cataracts. Nuts and seeds are fantastic sources of vitamin E – just a handful of almonds, sunflower seeds, or hazelnuts provides a large portion of your daily requirement. Other sources include wheat germ, avocados, and sweet potatoes. Including a mix of these healthy fats in your diet can help keep the tissues of your eyes resilient (Diet and Nutrition | AOA).
Lutein & Zeaxanthin: Lutein and zeaxanthin are antioxidants found in high concentrations in the macula (the central part of the retina responsible for detailed vision). They act like natural sunblock for your eyes, filtering harmful blue light and reducing oxidative damage. You’ll get plenty of lutein and zeaxanthin by eating dark, leafy greens such as spinach, kale, and collard greens. Other sources include broccoli, peas, kiwi, and eggs (the yolk contains these nutrients). Eating a spinach omelet or a kale salad a few times a week can boost your intake of these vision-protecting pigments (Diet and Nutrition | AOA).
Omega-3 Fatty Acids: Omega-3s are essential fatty acids that play a big role in eye health. DHA, a type of omega-3, is a major component of the retina. Getting enough omega-3s supports proper visual development in children and helps keep the retina healthy in adults (Diet and Nutrition | AOA). Omega-3s are also known to reduce inflammation and support the oily outer layer of the tear film, easing symptoms of dry eye (Diet and Nutrition | AOA). You can get omega-3s by eating fatty fish like salmon, tuna, sardines, and mackerel. If you’re not a fan of fish, flaxseed, chia seeds, and walnuts are also good (plant-based) sources of omega-3. Just two servings of fish per week can make a difference in your omega-3 levels and help keep your eyes lubricated and comfortable.
These nutrients work together to maintain healthy vision. A diet rich in colorful fruits and veggies, whole grains, and lean proteins will naturally provide a good mix of these eye-friendly vitamins. And the good news: taking care of your eyes can be delicious! Swapping in more of these foods—like a spinach salad with oranges and walnuts, or grilled salmon with a side of sweet potato—will benefit your eyes (and the rest of your body, too).
Nutrition and Age-Related Eye Concerns
Eating a nutrient-rich diet isn’t just about day-to-day vision; it can also protect your eyes as you age. Many common eye conditions that come with age can be delayed or mitigated with the help of the vitamins and minerals mentioned above. Let’s look at a few age-related eye concerns and how nutrition can help:
Macular Degeneration (AMD)
Age-related macular degeneration is a leading cause of vision loss in older adults. It affects the macula (the central part of the retina), causing blurred or lost central vision. A healthy diet can play a role in preventing or slowing AMD. Studies have shown that people who eat diets high in antioxidants (like vitamins C and E) and carotenoids (like lutein and zeaxanthin) have a lower risk of developing AMD (Diet and Nutrition | AOA). In fact, a landmark study by the National Eye Institute found that a high-dose combination of vitamin C, vitamin E, beta-carotene (a form of vitamin A), and zinc reduced the risk of advanced AMD by about 25% in high-risk patients (Antioxidant Vitamins and Zinc Reduce Risk of Vision Loss from Age-Related Macular Degeneration | National Eye Institute). This means that eating foods rich in these nutrients (or taking supplements if recommended by your doctor) can help protect the macula. Leafy greens, orange fruits/vegetables, and nuts are all excellent choices for AMD prevention. If you have a family history of macular degeneration, paying attention to your diet now is a smart step to maintain your vision later.
Cataracts
A cataract is a clouding of the eye’s lens that leads to blurry vision and occurs mostly in older individuals. While cataracts are very common, especially after age 60, good nutrition may help delay their development. Antioxidant vitamins like C and E are thought to protect the lens from oxidative stress that can lead to cloudiness. For example, some research suggests that getting plenty of vitamin C can lower the risk of developing cataracts (Diet and Nutrition | AOA). Similarly, vitamin E and the carotenoids lutein/zeaxanthin may help slow the progression of cataracts (Diet and Nutrition | AOA). You can support your eyes by eating citrus fruits, berries, bell peppers (for vitamin C) and almonds, sunflower seeds (for vitamin E). And again, those leafy greens pull double duty here – their lutein and zeaxanthin content not only supports the retina but also the lens. While a healthy diet can’t completely prevent cataracts (factors like age and genetics also play a big role), it can certainly help keep your lenses clear for longer.
Dry Eye Syndrome
(10 Foods That Are Good for Your Eyes)Have you ever experienced stinging, burning, or a scratchy sensation in your eyes? Dry Eye Syndrome becomes more common with age (and with long hours of screen use). Diet can offer some relief for dry eyes as well. Omega-3 fatty acids, found in fish like salmon, flaxseed, and walnuts, are known to improve dry eye symptoms by supporting a healthy tear film. In one study, omega-3 supplements significantly reduced dry eye symptoms by increasing the eyes’ natural oil production for tears (8 Nutrients for Eye Health). These healthy fats reduce inflammation and help your tears lubricate the eye effectively. Vitamin A is also important here: severe deficiencies in vitamin A can cause dryness by damaging the glands that produce tears (Vitamin A Deficiency: Causes, Symptoms, Treatment & Prevention) (though such deficiencies are rare in developed countries). To combat mild dry eye through diet, make sure you’re staying hydrated (drink plenty of water) and include omega-3-rich foods weekly. If your eyes often feel dry, talk to your eye doctor – in addition to dietary tips, we can recommend treatments like artificial tears or prescription therapies.
Next Steps for Healthy Eyes
Nutrition is a powerful tool for maintaining healthy vision. By incorporating the vitamins and nutrients above into your daily meals, you’re doing your eyes a big favor.
