I use the recipe from the Master-Cleanse book. It uses ACV, raw honey and distilled water. I use it daily, sometimes twice a day. I like it. It seems to take the red out and improves my vision when it starts to feel "cloudy". I swim alot and I always use it when I come home. I have been using it for over 6 months. It stings, but just momentarily. Hope this helps. Aloha
