Urban dwellers often strain their eyes through constant phone scrolling and screen time, leading to blurry vision, dry eyes, and presbyopia. Pistachios, widely praised as an “eye-protecting snack,” have shown promise in supporting vision. Research has shown that eating 2 ounces of pistachios daily for 12 weeks can significantly increase macular pigment optical density, which helps protect against macular degeneration and related vision loss.

However, pistachios are just one piece of the eye health puzzle. A wide variety of lutein-rich superfoods can also offer powerful support for eye health and protection against screen-induced damage.

At the core of this protection is the macula, a crucial part of the retina responsible for sharp central vision. It depends on pigments such as lutein and zeaxanthin, two carotenoids that absorb harmful blue light, provide antioxidant defense, and reduce oxidative stress in both the eyes and brain.

Who Needs Lutein Supplementation Most

Yiling Huang, founder and lead nutritionist at the Koii Nutrition Counseling Center, shared her advice on the “Health 1+1” program on NTD, a sister outlet of The Epoch Times. She recommended lutein supplementation for these groups:

• Heavy Device Users: Extended screen time increases eye strain.


• Older Adults: Aging reduces the body’s ability to digest and absorb nutrients, making additional supplementation beneficial.


• People With Low Intake of Produce: Insufficient intake of fruits and vegetables contributes to a deficiency in antioxidants.

Lutein-Rich Foods for Eye Health

Although pistachios provide valuable vitamin E and essential fatty acids for eye health, moderation is key. The recommended amount of 2 ounces (57 grams) daily provides nearly 30 grams of fat, more than half the recommended daily intake. When combined with cooking oils, this can lead to excessive fat and calorie intake. Huang said limiting pistachios to 1 ounce (approximately 20 to 30 grams) per day, paired with lutein-rich dark green vegetables and orange-yellow fruits, offers optimal benefits.

Dark green vegetables and orange-yellow fruits and vegetables are primary sources of lutein and zeaxanthin. The high chlorophyll content in dark green vegetables masks the color of lutein. Common lutein-rich foods include:

• Dark Green Leafy Vegetables: Sweet potato leaves, baby bok choy, spinach, kale, broccoli, and Swiss chard


• Yellow and Orange Vegetables: Corn, pumpkin, carrots, and bell peppers


• Fruits: Kiwi, papaya, oranges, and tangerines

Huang said that to ensure sufficient intake of eye-protecting nutrients, she recommends eating at least one-half to one bowl of dark green vegetables daily, which provides approximately 6 to 12 milligrams of lutein. She also suggested pairing these with corn or citrus fruits to boost lutein and zeaxanthin intake.

Heavy screen users may benefit from up to 30 milligrams of lutein. However, as health and dietary needs vary, consulting a nutritionist for personalized adjustments is advised.

Maximizing Lutein Absorption

Many people find lutein supplements ineffective because they are taking them incorrectly. Since lutein is fat-soluble, timing matters. Huang recommended taking it after meals—especially those that include healthy fats—to improve absorption.

Taking it on an empty stomach is discouraged.

Additionally, the effectiveness of lutein is influenced by overall dietary intake. Pairing it with other antioxidants can create a synergistic effect, helping preserve lutein levels in the body and enhancing its ability to protect the macula.

Targeted Nutrition for Specific Eye Conditions

Supplementing with lutein alone may not address all eye conditions. Different eye issues require specific nutrients for effective relief:

• Dry Eyes: Vitamin A, docosahexaenoic acid from fish oil, and astaxanthin—found in shrimp, salmon, and seaweed—can help relieve dryness.


• Eye Fatigue: Astaxanthin and anthocyanins help relax the eye muscles, making them suitable for people who frequently use digital devices up close.


• High Intraocular Pressure (Glaucoma): Anthocyanins improve blood circulation within the eyes and support the health of tiny blood vessels, while astaxanthin also provides support.


• Cataracts: Taking vitamin B1, along with managing blood sugar, blood pressure, and cholesterol, can help prevent cataracts.


• Presbyopia (Farsightedness): Beta-carotene, vitamin E, lutein, zeaxanthin, and vitamin C provide antioxidant protection that may help with presbyopia.

Huang said her eye care routine includes eating carrots for their beta-carotene, as well as eating dark green vegetables such as spinach, sweet potato leaves, and amaranth. At times when she has not eaten enough fish, she takes fish oil to boost her docosahexaenoic acid intake, which helps keep her eyes moisturized and prevents dryness.
