None of the things you mention will have any real effect in either improving or protecting your vision.
I take Lutein. It is a supplement used to slow aging, treat cancer, and to prevent cataracts and macular degeneration.
carrots...........
Vitamin A is definitely indicated for eyes. Don't OD on it though, as it can make you sick.
I took an herb called Ging Quae (or something like that) which is supposed to be for depression, but for some reason it made my vision sharper.
I don't think any of these things will change your glasses prescription, though. Get lasic surgery.
