One of the most frequently asked questions is the difference between Areds and Areds 2. Actually the original formula is quite powerful and helpful for AMD to lower the blurry vision. However Areds 2 is the newer version and without the beta carotene formula it is also suitable for smokers. In the Ared formula there was no Lutein or Zeaxanthin but beta carotene. In the newer version of Ared 2, the lutein and Zeaxanthin are included.
