Having been to UCI Irvine, I was told to prepare for diminishing eyesight. Reading is my passion and I noticed that it was getting harder to keep the printed lines straight. Night driving was scary, the oncoming lights blinded me, I read the reviews on Astaxanthin and used one bottle, not really sure if it would help. Well last night I had to drive From Sun City to Chino, Friday eve. traffic, and I COULD SEE! I told the wife, "I can see the lines on the pavement". I just couldn't believe I could see against all that outbound traffic. Needless to say I am ordering more! For me this is a MUST HAVE product. My father is 92 and has perfect eyesight, My hope, with Astaxathin, is to see untill at least 98 yrs. (or more) Only 65 now. Thanks so much.
