Probably the only thing thats going to put everything out is going to be lighting. If your in the dark your pupils will be naturally bigger.So I still can’t figure out how to safely post this pic but I found one of me from like 2013 or so with pupils huge.
I blew it up and then measured the grainy picture best I could with a ruler lol. I measured at two different zooms to try and get a better read.
Both measured in at around 80%.
But jeeze 80% is unreal hey ! Certainly dinner plates
