Fish-oil capsules are a top pick for dry eye, so a large trial deserves attention.
Retina ClearThe DREAM study
In the 2018 DREAM trial, about 500 people with moderate to severe dry eye took high-dose omega-3 or an olive-oil placebo for a year. Both groups improved, and omega-3 did not do better than placebo.
What that means
It does not prove omega-3 is useless for everyone, and milder dry eye was not tested. It does show that a supplement is not a sure fix.
What tends to help
- Artificial tears, used as directed.
- Warm compresses for oil-gland blockage.
- Screen breaks and humidity.
- An eye exam, since dry eye has several causes.
Retina Clear does not list omega-3, so this is background for readers comparing eye products.
