I use Genteal eye products all the time. An ophthalmologist recommended them to me and I'm hooked. There's several different types of Genteal products that are great for different levels of dry eyes. My everyday favorite it the Genteal Gel Drops. It's a moderate level of moisturizing and I really notice that they last a very long time. The Genteal Gel is great, but my only advice is to use at night before you go to bed. It make it a little hard to see since the gel is so thick. But the bonus is that you wake up with refreshed eyes!!
