Dry eye can impact your vision. You need that layer of moisture to properly focus. My optometrist recommended OTC saline eye drops in individual little containers. They help. I had no idea I had dry eye until he told me...I just knew that I found myself blinking a lot when night driving to try to see. It was the dry eye.
I have ALWAYS had trouble with night time driving, particularly in the rain, but its mostly related to having little or no distance vision - it is way harder to estimate how far away something is in the dark when you have no depth perception to speak of.
That said, if your vision has changed, there is a problem and you should see an ophthalmologist.
Also you need not vitamin A, but its precursor, beta carotene. Vitamin A builds up in the liver and can cause damage if you over do it. Beta carotene will convert to Vitamin A in the body and the excess beta carotene is easily shed. Way harder to over do it. Look for a beta carotene supplement. Or eat more carrots and sweet potatoes.

I posted in Alt Med about night vision support. Vit A is something I've never thought about but over many years heard "eat your carrots, they are good for your eyes"....that's the beta carotene.

One of the studies that led to this conclusion was conducted in Finland by the U.S. National Cancer Institute (NCI) and the National Public Health Institute of Finland. It found 18 percent more lung cancers and eight percent more overall deaths among 29,133 male smokers given a supplement containing 20 mg of beta carotene and 50 mg of vitamin E.
A second NCI-funded study found 28 percent more lung cancers and 17 percent more deaths among adults taking supplements of beta-carotene and vitamin E. This study included 14,254 men and women between the ages of 50 and 69 who were smokers or former smokers as well as 4,060 men between 45 and 69 who had been exposed to asbestos at work.
A third study, involving 22,071 male U.S. physicians, 11 percent of them smokers, showed neither benefit nor harm in the group that took beta-carotene.
None of these results suggests that beta-carotene supplements cause lung cancer, but they do indicate that they don’t help to prevent it where smoking is a risk factor.
My night vision has never been very good. It has always taken me 25 minutes or more for my eyes to adapt to a sudden change in lighting. I have never heard of any generally successful remedy for poor night vision except for cataracts, but that's not always the cause. Usually, you just have to adapt to it. Avoid driving after dark if need be. I do.
Basically when I drive at night I find it harder to see than I use to, and I have to drive slower, cause I'm afraid I'm going to something or afraid a car might come out of the dark, that I won't see coming since I feel my sight of distance isn't as good.
I guess I could go do the doctor about it, but I'm worried, is it just matter of something happening when one gets older? I'm in my early 30s now.
It does without saying to get an eye exam. You probably need glasses or a glasses prescription change. A good anti-reflective coating in your glasses can do wonders in improving night driving. Glare from the headlights of oncoming cars, fluorescent street lights, and other objects can negatively affect your night driving. Photochromic coatings (i.e. Transitions) will not reduce glare at night. It only reduces daytime glare.
Oh okay. I don't think glare is the problem, things just look darker. But I will get it checked and see...
