Really great solution that leaves your contacts clean and your eyes feeling refreshed after using it. This is a leading brand and I think that's for good reason. The solution is simple to use, you just pour it onto your contacts, rub them a little bit if you want to get off extra dirt, and then place them into a contact case with the solution to soak. The replenish solution does a fantastic job at keeping your contacts clean of excess debris and dirt that might build up over regular daily use of your contacts, and irritate your eyes giving you infections and things like that. While using this solution, I haven't really suffered from things like eye infections or scratches like I used to in the past. I also think that this solution hydrates your contacts really well, thus keeping your eyes from drying out too quickly as well. My eyes are normally pretty dry and I find that using this solution helps greatly to alleviate those dry eye symptoms.
