Do you often experience dry, stinging eyes, or even blurred vision and fatigue after a full day of screen time? Don’t assume this is only an issue for older adults—more and more young people are now struggling with dry eye syndrome. According to a clinical study published in Antioxidants in January 2025, nutritional supplements may offer new hope for those suffering from dry eyes, but experts stress that choosing supplements wisely and taking them in the correct dosage is crucial—don’t rely on them excessively.
Dry Eye Doesn’t Just Affect the Elderly: The 3C Generation Is Also at Risk
Modern life is inseparable from smartphones and computers. Staring at screens for long periods without blinking leads to advancing onset of dry eye syndrome. Simply put, it results from insufficient or poor-quality tear production, causing symptoms such as dryness, itching, redness, or a gritty sensation. Research shows that 5%–50% of the global population is affected by dry eye syndrome. Taiwan is no exception, and the incidence among individuals aged 20 to 40 has been rising year by year.
Traditional Treatments Have Limitations; Nutritional Supplements Are an Emerging Trend
Historically, relief for dry eyes has come from artificial tears, medications, or topical treatments—methods that mainly offer temporary symptom relief without addressing underlying causes. In recent years, scientists have begun exploring the effects of nutrients on eye health. They have found that fish oil (EPA, DHA), lutein, and zeaxanthin possess antioxidant and anti-inflammatory properties that may benefit individuals with dry eye symptoms.
In this latest study, 52 participants with dry eye were divided into two groups: a control group and a supplement group. The supplement group took a daily formulation containing 45 mg EPA, 30 mg DHA, 30 mg lutein, and 1.8 mg zeaxanthin for 12 weeks. Tear production was assessed using the Schirmer test, and symptoms were measured via the Ocular Surface Disease Index (OSDI). Inflammatory markers and oxidative stress levels were also monitored in both blood and tear samples.
After 12 weeks, the supplement group showed a notable increase in tear production and a decrease in OSDI scores—indicating reduced dryness and stinging. Most importantly, levels of inflammatory markers like IL-6 and IL-8 also decreased, suggesting reduced ocular surface inflammation. These findings imply that such nutritional supplements may not only alleviate symptoms but also address underlying physiological factors.
Daily Care Tips for Dry Eye Relief
Take a 3–5 minute break every 30 minutes of screen time
Maintain indoor humidity; avoid prolonged exposure to air conditioning
Blink frequently to reduce tear evaporation
Stay hydrated to support overall moisture balance
Eat a varied diet rich in fruits, vegetables, fish, and whole grains
Have regular eye check-ups and seek professional advice promptly
Expert Insights: Safety Is Paramount
Although supplements show promise, nothing works universally. Yoana, Food Technologist, advises:
“Before supplementing with fish oil or lutein, consult a professional—especially if you have chronic conditions or take medications. Choose products with proper certifications and clear labeling, and never exceed recommended dosages.”
Nutritionist Sharon adds:
“Eating whole foods like fatty fish, leafy greens, corn, and egg yolks regularly provides these nutrients. Supplements should only complement—not replace—a healthy diet and lifestyle.”
For personalized guidance, consult an ophthalmologist or licensed nutritionist.
