@am1953 - You might want to discuss it with your ophthalmologist. I think you probably are taking AREDS 2 now. I think Preservision is part of the brand name of the AREDS 2. Here's an old article from 2013 when AREDS changed to AREDS 2 - Which is Better: AREDS 1 or 2?: https://www.reviewofoptometry.com/article/which-is-better-areds-1-or-2. Then there was some confusion when AREDS 2 changed to the "New" AREDS 2 - https://www.scottpautlermd.com/confusion-between-preservision-areds-2-and-new-preservision-areds-2/
