This thread makes me laugh.
I'm an eye doctor and I would tell the original poster to go see an eye doctor. you ned glasses! There is no supplement or any eye exercises that will help. At all. Period.
Those eye exercises is called "The See Clearly Method" and it is not only an outrageous lie but a waste of time and money. The only eye exercises that work to improve vision is when people have Vision Therapy, but those patients have an issues that needs to be corrected (amblyopia, strabismus, etc...).
Vitamin A is fat soluble so you don't want to be taking a lot of Vitamin A. All it does is improve your rod sensitivity for night vision (very slightly). Not worth it.
Betacarotene is the same as Vitamin A except it can cause cancer if you smoke. So bottom line is if you smoke stay the f**k away.
Blueberries. LOL. Never heard that one.
Lutein is in something called "ICaps". More for preserving vision rather than "gaining" or recovering lost vision. Don't take until you are over 50.
Bottom line: See your eye doctor and get glasses or contacts.
