I believe it was Soulful that noticed improved vision (among other benefits of iodine)...I am now too.
It's been happening for maybe a month? I noticed myself squinting really hard to see a friend that was walking towards me. Even watching TV, I have noticed the difference. So I took my contacts and/or glasses off and could tell I wasn't as blind as I used to be. I will get my validation at the eye doc next month.
