Whilst luckily I don't have issues, an old riding buddy of mine is a good example. A specs wearer since his teens & now 73, he had been suffering with halos, dazzle & was feeling downright unsafe at night. As other have found, turned out to be cataracts developing, although not yet considered sufficiently 'ripe' for a lens replacement.
However, he was having none of that talk, so had both lens done last Spring - what a difference. Excellent vision at distance, peripheral restored; still needs reading glasses though as he decided against the cost of torics. No capsule problems, night vision pretty well restored. The strangest thing for him was no longer needing specs most of the time - glasses had become part of his life for 60 years, something to hide behind perhaps & look through like a window on the World. His message is go with the lens replacement route if you are developing cataract issues - there is a rsik factor, but it remains small if you are otherwise healthy.
