vitamin/mineral supplementation and deficiency
"I was told to take PreserVision AREDS 2 after an eye exam where the Dr. thought he saw early possible macula degeneration   in one eye. I took them every day and was noticing that my sight seems to be deteriorating and I had more floaters. My eyes seemed tired more after playing piano or reading. Then I ran out and spent a few days without them. My vision improved greatly! Less floaters and more able to focus on different tasks. I just played piano without my glasses! Go figure. Gotta talk at my appointment in June but I don't think my body Likes them."
