魚油 / Omega-3 Omega-3 / Fish Oil × 乾眼症
結論：證據分歧
證據呈現高度分歧：2019 Cochrane（Downie）與 2023 O'Byrne 更新版整合分析認為證據異質性高、客觀指標不一致；2019 與 2023 另兩篇 MA 則支持主觀症狀改善。

關鍵 DREAM 試驗（n>500）為陰性結果，NIH ODS 亦明確列為 no consistent relationship。
雖有機轉（強化瞼板腺油脂層）與部分小型 RCT 支持，但高品質試驗多為陰性或僅見主觀改善，符合 C（弱證據／結果不一致）等級。

Research studies looking into the benefits of omega-3 fatty acid supplements have found fewer dry eye symptoms in people who take the supplement. It appears that omega-3 fatty acids can improve the eye's oil film that's produced by small glands on the edge of the eyelid, called the meibomian glands. That improves dry eye symptoms and reduces the need for artificial tears. The dose of omega-3 fa… 來源↗

Fish oil supplements do not appear to benefit patients with dry eye. There's no strong evidence that this is true, unfortunately... Long-term supplementation with marine omega-3 fatty acids does not decrease the incidence of dry eye diagnosis or severe dry eye symptoms. This study, therefore, does not support use of omega-3 fatty acids to prevent dry eye disease. 來源↗

TW 社群普遍認為魚油（Omega-3）對乾眼症「有幫助但非萬靈丹」，多搭配葉黃素一起補充；重度乾眼者單靠魚油常感不足，仍需配合人工淚液、熱敷或脈衝光治療。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實以為魚油可以單獨『治癒』乾眼症，但實際上只是輔助保養
✓
事實認為所有魚油效果都一樣，忽略 rTG/TG/EE 型式與 Omega-3 濃度差異
✓
事實誤以為吃越多越好，但高劑量可能造成腸胃不適或出血風險
✓
事實把魚油和魚肝油混淆（後者主要是維生素 A/D）
✓
事實以為短期吃 1-2 週就會有感，實際上多數人需連續補充 2-3 個月以上
🩹 社群通報的副作用
- 打嗝有魚腥味
- 腸胃不適、輕微腹瀉
- 服用過量可能延長凝血時間（術前或服用抗凝血藥需停用）
- 部分人反映吃完有反胃感
