Dry eye can be eased with fish oil supplements, according to new research from India.
In a three-month study, 478 people with dry eye as a result of excessive computer use were given either two omega-3 pills a day, or placebo pills that contained olive oil.
The results, published in the journal Contact Lens & Anterior Eye, showed that those taking fish oil experienced a greater reduction in symptoms than the olive oil placebo.
They also had more conjunctival goblet cells on the surface of the eye – these cells are responsible for lubrication.
Omega-3, which is also found in walnuts, is thought to help by reducing inflammation and promoting circulation to improve eye health and increase tear production.
