They work, and are convenient.
These really helped when other solutions didn't.  I have problems with chronic dry eye after a facial surgery.  I love that the vials are resealable, and each one contains plenty for a day or more.<br /><br />Every so often (maybe every 3 days) my eye feels a little "goopy" from this stuff, but it clears out easily and is so worth it.
