Generally the bigger the objective lens the better you can see. Glass quality and size is the most important part of any piece of optical equipment, and cheap glass is going to be a mistake. Digital enhancement is going to help in a small way but is limited to exactly that, digital cannot make up for poor glass size and quality.
ok thanks, I had googled and saw a few things that said the opposite from each other. I knew that as far as a regular scope goes, the bigger the lens the more light can be gathered which mean the longer you can see in low light but wasn't sure about the night vision since you can in essence switch to night vision in low light. the reason I'm asking is I'm looking into a sightmark wraith 4k 4x32 scope. academy sports has a 40mm and a 50mm lens. I'd rather go with the 50mm but it's out of stock. I can get the 40mm around the 1/24. what do you think?

You are correct that 50mm is supposed to be better for low light conditions and a wider field of view. However I can always see better in the middle of the day with 50mm vs 40 mm, I think it's got something to do with "a brains ability to perceive and process what we're seeing" better because of the wider angle and the better light. I think I'd be ok with the 40mm if that's what's available, but the 50mm would be worth holding out for if you can find it.
In night vision the price increases drastically for higher power scopes but IMO they are worth every penny. I go coyote hunting sometimes with a 50X ATN Thermal and it's an amazing piece of equipment, you can identify an eight point buck in the middle of the night at 800 yards.

Hopefully you go thermal, vs. NV. ATN is an entry level optic, but they don't get rave reviews from experts in the field. I've used one, it wasn't bad. I opted for a clip on. It mounts ahead of your day scope. So your Leupold or other scope that is already on your rifle is your sighting device, the clip on just allows you to see at night with your scope. The beauty is you are able to switch it from rifle to rifle, no need to "sight in", can be used stand-alone as a monocular or for searching for wounded game, etc. The negative is expense (like all of them) and the mounting solution for some rifles is complicated. An AR style rifle with a quad rail is easy, but a standard bolt action, takes a special mount to get a rail ahead of the day scope.
I have a Burris, it's pretty descent.

Could you post a link to the one you use? Thanks.
will do. I checked on the sightmark website and they're out of stock on the 50MM.

It uses CR123 batteries. I have 8 rechargable ones I carry. It takes 2 to run it. If you leave it on, it will run about an hour on 2, non-stop. I can get 4 hours out of my 8 rechargables, plus or minus.
