What factors could cause distance vision to worsen with age?

Change in power: While most people complain of worsening near vision with age, distance vision can also be affected. This is usually the result of changes in the optics of the eye (lens and cornea). You can become more nearsighted or develop more astigmatism over time, even if your prescription has been stable for years or you have never worn glasses. I recommend you see your eye doc to be sure.
