PHILADELPHIA (CBS) - Dry eye syndrome is a problem which affects more than 8 million people in this country. For many people, eye drops that adjust the lipid layer can be of help. That’s because dry eye syndrome is associated with a decline in the quality of tears that bathe the eye and keep them moist.

Symptoms include pain, irritation, and dry or a sandpaper-like sensation.

There are many causes, or suspected causes. A surprising one is diet — in particular, omega-3s.  Fish and walnuts are high in the omega-3s.

It clearly shows that our diet and nutrition can have a role in just about everything in our body.
