Older man with dry eye rubbing his eyes while holding his glasses

Answer:

Certain supplements have shown benefit in alleviating symptoms of dry eye. These include fish oil, flaxseed oil, and, possibly curcumin (from turmeric). However, these effects have only been shown in preliminary studies. Better studies are needed to confirm these benefits. For details, including formulas and doses that have shown benefit, sign in.

Can you comment on supplements like Preservision? Does that help with dry eyes?

There is no evidence that PreserVision can improve dry eye. Although another supplement similar to one of the PreserVision formulations used in clinical research (this formulation is not available in the U.S.) did show benefit for dry eye symptoms, the primary ingredient in this formulation was omega-3 fatty acids. Omega-3 fatty acids alone can improve dry eye (as noted in our answer above), but there is no evidence that added vitamin/antioxidant ingredients - such as those in PreserVision - provide additional benefit for dry eye.
