The study results refute the long-held belief that EPA and DHA -- types of Omega-3 -- reduce dry eye symptoms.
Even the highest dose of Omega-3 supplements ever tested, did not show significant difference than placebo in outcomes for participants, the researchers said.
"Our findings provide evidence that, contrary to a long-held belief in the ophthalmic community, Omega-3 supplements are not significantly better than a placebo at reducing dry eye symptoms," said Maureen Maguire, Professor at the University of Pennsylvania, US.
"The results are significant and may change the way a lot of ophthalmologists and optometrists treat their patients," added Vatinee Y. Bunya, Assistant Professor at the varsity.
For the clinical trial, published in the New England Journal of Medicine, the team enrolled a total of 535 participants with at least a six-month history of moderate to severe dry eye.
After 12 months, the researchers found that participant's symptoms had improved substantially in both groups, but there was no significant difference in the degree of symptom improvement between the groups.
