I don't see any good scopes that are "better" for ageing eyes. Just don't buy crap optics. Will a 50 mm objective help you see better than a 42 mm objective? NOPE!
The "A big objective gathers more light." B.S. is something optics experts laugh at.
Sorry, I would have to disagree.
High power scopes require a larger objective lens than a low power scope. You don't see a 25x scope with a 1'' objective because there is a reason. just like you don't need a 2x scope with a 50 mm objective lens.
I have many 1'' to 40 mm scopes and none of them are any good for poor light. A larger objective has the ability to gather more light, but the scope quality has an effect on how well the scope transfers the light through the entire scope. A "big poor quality lens" doesn't do any better than a "small good quality lens" so quality of the glass plays a major role in the ability to transmit the available light. But if you get a quality glass in a large objective and a quality scope, it will Work better in poor light.
With all things being the same quality and magnification, the larger the objective, the better it's ability to gather light. In simple terms a 30 mm objective is better than a 20 mm lens. A 40 mm is better than a 30 mm and a 50 mm is better than a 40 mm and so on.
On some rifles I prefer the smaller objective for many different reasons but on rifles that are intended to be used for poor/low or night use the bigger the objective the better. I have one such set up on a night hunting rifle (For Hogs) I can use a green illuminator that has a 8' circle of light at 100 yards that does not spook the hogs because it is very subtle and with the 55 mm scope the target is very clear. I don't have to use a night scope and can use the scope for day or night.
Nothing personal, just simple physics.
