“Omega-3 helps maintain healthy tears,” says Ocuvite Adult 50+ Eye Vitamin & Mineral Supplement. Can omega-3s cut your risk of dry eye disease?

Researchers randomly assigned 23,523 men aged 50 or older and women aged 55 or older to take either fish oil (460 mg of EPA + 380 mg of DHA) or a placebo every day.

After five years, the omega-3 takers had no lower incidence of dry eye disease or severe dry eye symptoms than the placebo takers.

What to do

Don’t expect omega-3s to cut your risk of dry eye disease. And daily omega-3s (650 mg of EPA + 350 mg of DHA) didn’t lower the risk of cataract surgery or advanced macular degeneration in the AREDS 2 trial.
