It's a bit hard to explain where this is from.
About 10 years ago, my parents who knew I was interested in optometry, gave me the "magazine" which is essentially an advertorial for some naturopathic pills. Inside, for some reason, there was 5 pages on eye health. Because of the quality of the overall Q&A, I kept it on my bookshelf. I was just cleaning things up this weekend, when I decided to look at it again.
