Or, will it prevent it from becoming worse?

Only if you're deficient in Vitamin A.

Only if you are deficient in Vitamin A (look in the Merck online manual) How to know if you are deficient? you would have a lot of other symptoms that would have driven you to the doctor before you got on here.
The idea that Vitamin A helped improve vision was a rumor started in WWII because the British didnt want the germans to know that they had developed radar. It was on the front page of the London Times that they had started to feed thier pilots carrots to help them hit targets.
High doses of A is toxic.
Eat more veggies and fruits. Eat the Rainbow - Produce of all colors, and you wont have to worry about your Vitamin A intake.

Vitamin A is a key component to a compound in the eye called visual purple, or rhodopsin. This is involved with the retina being able to respond to low light levels. A vitamin A deficiency will thus lead to night blindness. Adaquate intake of vitamin A will prevent night blindness but will not affect vision in any other manner.

It depends on your particular vision problem, and what the cause is.
Vitamin A is used by your body to make the photosensitive pigment that your eyes use for night vision. Therefore, if you are low on Vitamin A (and therefore don't have enough of that pigment), taking the supplements might improve your night vision. If you have a vision problem that is caused by something else, Vitamin A wouldn't necessarily help.
If you are worried about your vision, please see your eye doctor and ask his/her advice.

Take your vit. A if you want to improve your vision. Years ago in villagers in nepal especially children suffer greatly from blindess. It wasn't long for the WHO (world health organization) to act and immediately organized a campaign encouraging villagers to take the supplement (vit. A). In the end people where happy that their vision improved significantly within a year.

vitamin A has a trophic effect on the retina. If it improves vision depends on the cause of vision loss, but it prevents age related degeneration of retina.

It, along with some other supplements, (Lycopene from tomato catsup/ketchup and Billberry Supplements and Beta Carotene) should help. I forgot where I read it, but I read somewhere that people with blue eyes have a tendency to go blinder quicker (because, I'm guessing, the lighter color makes it more succeptible to damage)... Us poor people with blue eyes... I take my Billberry Supplements almost every day. Maybe this will help you :)
