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 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. Fish oil does not seem to help prevent or treat dry eye when used alone, although it might have some benefit when used with other fatty acids or vitamins. There is no strong evidence that supplementing with caffeine or drinking coffee is beneficial for dry eye.

For details, including formulas and doses that have shown benefit, and to find out if drinking extra water (i.e., more than what's needed to stay hydrated), following a gluten-free diet, or using eye drops containing castor oil, N-acetylcarnosine or aloe seems to help, sign in as a member.
