Omega-3 for Dry Eye
Omega-3 fatty acids improve meibomian gland function and tear film lipid layer quality, reducing evaporative dry eye that exacerbates eye strain. DHA also supports retinal photoreceptor membrane fluidity for efficient visual processing.
How strong is the research?
No Benefit evidence
A rigorous 12-month randomized trial of 535 adults with moderate-to-severe dry eye disease found that high-dose omega-3 fish oil supplements provided no meaningful improvement in symptoms or any objective eye measure compared to placebo.
How much to take
1000–2000 mg
Omega-3s support tear film quality which reduces eye strain symptoms. DHA is particularly important for retinal health.
When to take it
Best taken: with food
