5 Eye-Healthy Foods in Season This June

If you're hitting the farmers markets around Edmonds this month, you're in luck. June produce happens to be packed with the nutrients your eyes use every single day. Lutein, zeaxanthin, and beta-carotene are natural plant pigments that show up in a lot of what's coming into season right now, and they play a real role in protecting your eyes from oxidative stress and inflammation, while also supporting long-term vision health, especially as you get older. You don't need to overhaul your diet to take advantage of this, just know what to look for at the market. Here are five eye-healthy foods worth grabbing this June, along with what each one actually does for your eyes.

1.  Eye Healthy Foods: Leafy Greens: Kale, Spinach, Chard, and Collards

Dark leafy greens are some of the richest food sources of lutein and zeaxanthin available. These two carotenoids are unique because your body deposits them directly into the macula, the small area of your retina responsible for sharp, central vision, like the kind you need for reading or recognizing faces. The macula is sometimes called the eye's natural sunglasses, since lutein and zeaxanthin increase macular pigment density, which helps filter out harmful UV light, something especially useful during long summer days outside. Research has linked higher dietary intake of lutein and zeaxanthin with a lower risk of age-related macular degeneration later in life. One practical tip: lutein and zeaxanthin are fat soluble, so pairing your greens with a drizzle of olive oil or some avocado actually helps your body absorb more of them. A simple sauté with garlic and olive oil, a massaged kale salad, or a handful blended into a smoothie are all easy ways to work them in.

2. Carrots

Carrots have been the go-to eye-health food for generations, and the science holds up. They're loaded with beta-carotene, which your body converts into vitamin A, a nutrient that's essential for healthy night vision and for keeping the surface of your eye, the cornea, properly lubricated and functioning. Severe vitamin A deficiency is actually one of the few diet-related conditions that can cause real vision problems, which is part of why this connection became so well known in the first place. You don't need to eat a pound of carrots a day to get the benefit. Roast them with a little honey and thyme, blend them into a carrot ginger soup, or just snack on them raw with hummus.

3. Corn

Fresh, local corn is one of the few vegetables that's particularly high in zeaxanthin specifically, alongside orange bell peppers and egg yolks. That matters because of how these pigments actually arrange themselves in the macula: about half the lutein you eat converts into a related compound called meso-zeaxanthin, which sits at the very center, surrounded by a ring of zeaxanthin, with lutein filling in the outer edge. Grilled corn on the cob with butter and a squeeze of lime is a classic summer side or cut it off the cob and toss it into a black bean and corn salad for an easy lunch.

4. Peas

Sweet peas bring a combination of lutein, zeaxanthin, and vitamin C to the table, plus a good amount of fiber. The vitamin C is worth noting on its own, since it supports collagen production and the health of the small blood vessels throughout your eyes. Toss fresh peas into a pasta salad, blend them into a quick pea pesto, or just eat them straight out of the pod as a snack while you're prepping dinner.

5. Cherries

Cherries have one of the shortest growing windows of anything on this list, so it's worth enjoying them while they last. They're rich in anthocyanins, the antioxidant compounds responsible for their deep red color, which help your body manage everyday oxidative stress from UV exposure, screen time, and general aging. They're also a solid source of vitamin C, plus smaller amounts of beta-carotene, lutein, and zeaxanthin. Try them fresh, pitted and tossed into a salad with arugula, also in season this month, and a little goat cheese, or simply eat them by the handful as a snack.

Frequently Asked Questions

Can eating these foods actually prevent macular degeneration?

Diet alone can't guarantee you'll never develop macular degeneration or other eye conditions, since genetics, age, and other health factors play a role too. But a growing body of research links diets rich in lutein, zeaxanthin, and other antioxidants to a lower risk of AMD and slower progression in people who already have early signs of it. Food is one piece of a bigger picture that includes regular eye exams and managing things like blood pressure and smoking.

How much lutein and zeaxanthin should I aim for each day?

There's no official daily requirement. The 10 mg lutein and 2 mg zeaxanthin figure you'll sometimes see is the supplement dose used in the AREDS2 clinical trial, a major study on people who already had risk factors for advanced macular degeneration, not a general target for the average person. Some more recent research and many eye health supplements use a higher combined range, closer to 20-25mg of lutein and zeaxanthin together, since the eyes tend to be slower than other tissues to take up these nutrients. For most people, eating a variety of colorful produce regularly matters more than hitting a specific number, and a cup of cooked spinach or kale alone gets you in that general range.

Is it better to eat these foods raw or cooked?

It depends on the food. Leafy greens hold onto their lutein and zeaxanthin well whether raw or cooked, and pairing them with a fat source like olive oil helps either way. Some nutrients, like the lycopene in tomatoes, actually become easier for your body to absorb after cooking.

Should I just take a supplement instead?

Whole foods are generally the better starting point, since they come with fiber, water, and other nutrients that work together, and there's less risk of overdoing any one nutrient. If you have an eye condition like AMD, ask Dr. Wong whether a specific supplement makes sense for your situation.
