You can't improve your eyesight, but you can maintain it. I'm sure you've heard carrots are good for your eyesight. Yes, this is true along with any form of vitamin A, but only for maintaining vision. Kinda like hearing; if you expose yourself to loud sounds for long periods of time, you start to damage your ears permanently and can't get it back.
However, if you are suffering from a serious vision problem due to Vitamin A deficiency, there is a good chance you can regain some vision. But I doubt you have that problem.1
