Not sure what type of scope you have. I would say you would be better off spending on better glass vs bigger. Maybe a different reticle.

I have a Leupold vx3i 3.5x10x40 and Zeiss 3x9x40 and a two Vortex Diamondbacks 3x9x40.Was wandering if 50mm would make a difference.

Now that my eyes are older do you think I would gain much moving up to 50mm on a scope/

Here's what you'll gain: weight and bulk
Some good advice below about going with better glass. Sucks that it is more expensive, but can be worth it.
 
50 mm.......higher rings.....weird cheek weld to the stock.......been there and done it............no advantage other than spending more money IMO.
 
It all depends on the magnification. 50mm objective only makes a difference on the high end. The exit pupil needs to be about 7mm for young eyes. A larger objective keeps the exit pupil at or above 7mm at higher magnification levels. As we get older our pupils no longer dilate to 7mm, so a large objective loses it's value because we can't make use of the larger exit pupil anyway.

The biggest advantage I found with a larger objective scope was easier / faster target acquisition.
Especially for a deer that was walking at a steady pace through heavy timber.
Just made it easier for me to make the transition of watching with my naked eye to getting it in the crosshairs.

I much prefer the 50 mm to the smaller ones.

That's just me though.

As for lighter, they say it don't matter.
