Helped first but no longer
I gave it 3 stars as I'm not sure it helps.  Even though the seller says it would take time to notice the effect, my Mom, who I bought it for, felt it already after a week, so we were very happy at first.  Unfortunately, at 3 weeks her eyes went back to extremely dry and painful.  I'm not sure at this point why this happened and whether we should continue or not.  These supplements are quite expensive to use without real effect.
