Anyone over 65 should seriously consider not driving, at least at night. Reaction times slow, night vision is poor/glare from oncoming headlights is worse. I'm not even 60 yet and I don't like driving at night anymore. The insanely bright, white, pinpoint headlights on modern cars make it that much worse.
I'm 50 and I can see just as well at night as I can in the daytime. Presbyopia means I cannot clearly read the instrument cluster without my glasses on, but I can read the text message the guy three cars in front is sending. Not that you should really need to read much on the gauges anyway - all the things that are going to get you into an accident are outside the car, and that's where your attention needs to be.

Not always. If you don't spot that your engine temperature is rising, or your fuel level is low, you might suddenly find yourself sitting in a non-running car on a busy expressway, as opposed to having a least a few minutes to find a safe place to pull over.
Best to develop a habit of continually scanning the gauges, mirrors, while your primary focus is on the road ahead. That way you are aware of the operating condition of your car and the traffic all around you, not just in front of you. You only need quick glances at the dashboard and mirrors to stay on top of things.
