Ana is right. I had the worst dry eye symdrome imaginable and did everything opthomologists recommended. It was so bad that my lid stuck to my eye ball and caused cornea errosion. After a friend recommended flax seed oil and an optomitist recommended Lutein I used both and in a few months hardly had dry eye at all. Still use preserative-free drops several times a day and sometime Genteal Gel at night. Stay out of wind, and away from smoke. Eat foods rich in Lutein and take the softgel caps. It also helps prevent Macular Degeration. I forget for hours that I had dry eye, then remember to use a couple drops of Tears Natural Free. Good luck, protect your eyes for life. Mary
